Instructions for building on macOS using CMake.
  
:http://developer.apple.com/downloads
+
Building on macOS has been made much simpler with the Audacity 2.4.0
 +
release. Still, read this document throughly before starting.
  
Xcode 3.2.6 is the last version that (officially) supports the PPC architecture and the macosx10.4u SDK.  Unless you're building release versions, the PPC support isn't absolutely necessary, but the SDK is required.
+
1) Get and install the latest Xcode version available your macOS version:
  
Enter “Xcode 3.2.6” in the search box on the left, press enter, and download the “Xcode 3.2.6 and iOS SDK 4.3” dmg:
+
      MacOS                  Xcode Version (as of Mar 2020)
 +
      Catalina - 10.15        11.3
 +
      Mojave - 10.14          10.3
 +
      High Sierra - 10.13    9.4.1
 +
      Sierra - 10.12          9.2
 +
      El Capitan - 10.11      8.2.1
 +
      Yosemite - 10.10        7.2.1
  
:[[File:Bom xcode 326 download.png|780px]]
+
2) Clone the Audacity repository:
  
== Download Xcode 4.5.2 ==
+
      git clone https://github.com/audacity/audacity
  
Snow Leopard users may skip this step.
+
3) Clone wxWidgets 3.1.3:
  
NOTE: You may choose to install other versions of Xcode, but at the time this guide was written, 4.5.2 was the latest and other versions may not work as outlined here.
+
      git clone --recurse-submodules https://github.com/audacity/wxWidgets.git
  
Enter “Xcode 4.5.2” in the search box on the left, press enter, and download the “Xcode 4.5.2” dmg:
+
  Ensure that you clone with the "--recurse-submodules" option, and do not
 +
  just download the Zip package, otherwise there will be required components
 +
  missing.
  
:[[File:Bom xcode 452 download.png|780px]]
+
  Don't be tempted to use wxWidgets already installed by a package manager
 +
  such as Homebrew because this will cause problems.
  
Enter “Command Line Tools” in the search box on the left, press enter and download the “Command Line Tools” dmg that corresponds to your version of OS X:
+
  We have applied some Audacity specific patches to wxWidgets to better
 +
  support VoiceOver, so please use the audacity-fixes-3.1.3 branch. It's
 +
  the default branch on our GitHub copy:
  
:[[File:Bom tools 452 download.png|780px]]
+
      https://github.com/audacity/wxWidgets/tree/audacity-fixes-3.1.3
  
== Download MacPorts ==
+
  You can be certain the correct branch is active with:
  
Two build utilities, cmake and pkgconfig, will need to be installed and MacPorts or Fink are the easiest way to get them. This guide will use MacPorts so you will need to make adjustments if you choose to use Fink or other source.
+
      git checkout audacity-fixes-3.1.3
  
Download the version of MacPorts which matches your OS X version from:
+
4) Change directory to the folder where wxWidgets was cloned and build it using:
  
:http://www.macports.org/install.php
+
      sudo <path to Audacity source>/mac/scripts/build_wxwidgets
  
:[[File:Bom macports download.png|780px]]
+
5) The config command should return "3.1.3" if the install was successful:
  
== Download wxWidgets ==
+
      /usr/local/x86_64/bin/wx-config --version
  
You must download the wxMac version 2.8.12 of wxWidgets from:
+
6) Now that you have wxWidgets installed, edit your ~/.bash_profile or
 +
  ~/.zprofile and add:
  
:http://www.wxwidgets.org/downloads/
+
      export WX_CONFIG=/usr/local/x86_64/bin/wx-config
  
[[File:Bom wxwidgets 2812 download.png|780px]]
+
  Log out and back in again (or reboot) for this to take effect.
  
Download the "[[Media:Build wxwidgets.gz|Build wxwidgets.gz]]" script that will be used to build wxWidgets for use with Audacity.  Make sure you save the file as "build_wxwidgets.gz".  Safari will automatically uncompress the file, others may not.
+
7) Download the CMake 3.16.4 DMG from:
  
== Install Xcode 3.2.6 ==
+
      https://cmake.org/download
  
Locate the Xcode 3.2.6 dmg, xcode_3.2.6_and_ios_sdk_4.3.dmg, on your system and double click it to have Finder verify and mount it:
+
8) Double click the DMG, follow the prompts and drag the CMake app to the
 +
  Applications folder.
  
[[File:Bom xcode 326 mount.png|center|480px]]
+
  If you will be building from the command line, open the CMake application
 +
  and click the "Tools -> How to Install For Command Line Use" menu. It will
 +
  give you additional instructions on making CMake available to the command
 +
  line.
  
The “Xcode and iOS SDK” installer checks the version of OS X that is currently running and it will not work on any version above Snow Leopard.  However, this version check can be bypassed by starting the installation from the command line.
+
  You are now ready to start building Audacity.
  
NOTE:  It is advisable to have all OS X updates applied to your system before installing Xcode 3.2.6.  This is especially important for Lion users as the installation will fail.
+
BUILDING USING THE CMAKE GUI
  
Open a Terminal window and start the installation by entering the following commands:
+
  NOTE: Building with the GUI interface will result in the downloading of
 +
        another copy of wxWidgets from Audacity.
  
:export COMMAND_LINE_INSTALL=1
+
1) Open the app.
:open "/Volumes/Xcode and iOS SDK/Xcode and iOS SDK.mpkg"
 
  
[[File:Bom xcode 326 install.png|780px]]
+
2) Click the "Browse Source..." button and locate the top of your Audacity
 +
  source tree, then click the "Open" button.
  
This will start the installation while bypassing the version check:
+
3) Click the "Browse Build..." button and find the location where you want to
 +
  put the build (use the "New Folder" button at the bottom left to create a
 +
  new folder).
  
[[File:Bom xcode 326 installer.png|780px]]
+
  This folder does not have to be in or even near the source tree, but it
 +
  must not be the same as the source tree. However, it is common to make it
 +
  a subdirectory of the Audacity source tree.
  
Proceed through the various installation pages until you get to the “Custom Install” page:
+
4) Click the "Configure" button and when the dialog pops up, select "Xcode" for
 +
  the generator, then click the "Done" button.
  
[[File:Bom xcode 326 custom install.png|780px]]
+
5) Click the "Generate" button to create the Xcode project.
  
Open the Essentials item by clicking the arrow:
+
6) Now you can either click the "Open Project" button or go to your "Build" folder in
 +
  Finder and open the Xcode project as normal.
  
[[File:Bom xcode 326 options.png|780px]]
+
BUILDING FROM THE COMMAND LINE
  
The minimum required options are “Unix Development” and “Mac OS X 10.4 SDK”, but if you're running Snow Leopard, you may elect to install everything.  On Lion or above, you will not be able to use “System Tools” and may choose to use the “iOS SDK” and “Documentation” from Xcode 4.5.2:
+
1) Change directory to your Audacity source tree.
  
[[File:Bom xcode 326 selected options.png|780px]]
+
      cd audacity
  
Continue through the pages to start the installation and close the installer when complete:
+
2) Create the "build" folder (name it anything you like):
  
[[File:Bom xcode 326 complete.png|780px]]
+
      mkdir bld
  
This completes the Xcode 3.2.6 installation.
+
3) Change to the "build" folder:
  
== Install Xcode 4.5.2 ==
+
      cd bld
  
Snow Leopard users should skip this step.
+
4) Configure and generate the Xcode project:
  
Locate the Xcode 4.5.2 dmg, xcode4520418508a.dmg, on your system and double click it to have Finder verify and mount it:
+
      cmake -G Xcode ..
  
[[File:Bom xcode 452 mount.png|center|480px]]
+
5) Build Audacity using the CMake command or xcodebuild:
  
The Xcode folder will open when it's mounted:
+
      cmake --build . --config Release
  
[[File:Bom xcode 452 folder.png|780px]]
+
      xcodebuild --configuration Release
  
You may choose to drag the Xcode app to wherever you like, but this guide expects it to be located in the Applications folder:
+
  The "Audacity.app" bundle will be in the "bin/Release" subdirectory of your
 +
  "build" folder, so you can start it via Finder or:
  
[[File:Bom xcode 452 copy.png|780px]]
+
      open bin/Release/Audacity.app
  
Locate the Command Line Tools dmg, xcode452cltools10_76938212a.dmg, on your system and double click it to have Finder verify and mount it:
+
Notes:
  
[[File:Bom tools 452 mount.png|center|480px]]
+
  - If you'd like to get a completely clean build, just delete "build" folder
 +
    and return to step 2 above.
  
The Command Line Tools folder will open:
+
  - Once the Xcode project is generated, you shouldn't have to "configure" or
 +
    "generate" again as it will be done for you automatically after pulling
 +
    updates and building.
  
[[File:Bom tools 452 folder.png|780px]]
+
    For example:
  
Start the installation by double clicking the installer, “Command Line Tools (Lion).mpkg” in this case:
+
        cd <audacity> directory
 +
        git pull
 +
        cd bld
 +
        cmake --build . --config Release
  
[[File:Bom tools 452 installer.png|780px]]
+
  - Instructions on optional signing of DMGs, showing languages other than English,
 +
    and other useful information can be found on our wiki at:  
 +
    http://wiki.audacityteam.org/wiki/Building_On_Mac
  
Once the installation completes, close the installer:
+
</pre>
  
[[File:Bom tools 452 complete.png|780px]]
+
== CMake Build ==
  
Open a Terminal window and enter:
+
<pre>
 +
1) Change directory to your Audacity source tree.
  
:sudo xcode-select -switch "/Applications/Xcode.app/Contents/Developer"
+
      cd audacity
  
[[File:Bom xcode 452 switch.png|780px]]
+
2) Create the "build" folder (name it anything you like):
  
You will be asked to enter your password:
+
      mkdir bld
  
[[File:Bom xcode 452 switched.png|780px]]
+
3) Change to the "build" folder:
  
To make it a little easier to use Xcode 3.2.6 from the command line, create a link to the 3.2.6 version of xcodebuild.  You make change the "xcodebuild3" to whatever you like, just remember when building Audacity from the command line to use what you specify here:
+
      cd bld
  
:sudo ln -s /Developer/usr/bin/xcodebuild /usr/bin/xcodebuild3
+
4) Configure and generate the Xcode project:
  
[[File:Bom xcode 452 xcodebuild3.png|780px]]
+
      cmake -G Xcode ..
  
This completes the Xcode 4.5.2 installation.
+
5) Build Audacity using the CMake command or xcodebuild:
  
== Install MacPorts ==
+
      cmake --build . --config Release
  
Locate the MacPorts installer and double click to start the installation:
+
      xcodebuild --configuration Release
  
[[File:Bom macports installer.png|780px]]
+
  The "Audacity.app" bundle will be in the "bin/Release" subdirectory of your
 +
  "build" folder, so you can start it via Finder or:
  
Click through the installation pages and close the installer when installation completes:
+
      open bin/Release/Audacity.app
 +
</pre>
  
[[File:Bom macports installer complete.png|780px]]
+
== For a Release CMake build ==
  
Open a Terminal window and install the cmake and pkgconfig packages:
+
Additionally:
  
:sudo port install cmake pkgconfig
+
<pre>
 +
6) Add the help files
  
[[File:Bom macports packages install.png|780px]]
+
  Open contents of bin/Release/Audacity.app
 +
  Add in files with directory help/manual/ and then the 5 top level items
  
You will be prompted to enter your password:
+
7) Notarize Audacity
  
[[File:Bom macports packages password.png|780px]]
+
  ../mac/scripts/build_dist.sh ../mac ../bld/bin/Release
 +
</pre>
  
The packages will be downloaded and installed:
+
For Notarization to work, you'll need to have already jumped through the Apple hoops, and have set up your signing file.  There are two stages to notarization, one for the bundle, one for the dmg.
  
[[File:Bom macports packages complete.png|780px]]
+
To test the Notarization, upload the dmg to dropbox and then download it again.  Then double-click to
 +
install and drag across to /Applications. When you launch Audacity, you now get a warning about having downloaded from the internet, rather than being prevented from running...
  
Add links to Xcode 3.2.6 so cmake and pkg-config can be located:
 
  
:ln -s /opt/local/bin/cmake /Developer/usr/bin/cmake
+
== Optional Extras ==
:ln -s /opt/local/bin/pkg-config /Developer/usr/bin/pkg-config
 
  
[[File:Bom macports packages link.png|780px]]
+
{{tip|'''FFmpeg and LAME'''
 +
For these, see [[Building Extras on Mac]]}}
  
This completes the MacPorts installation.
+
== Variations ==
  
== Install wxWidgets ==
+
{{note|1=These instructions for variations on building aren't in mac/build.txt in the Git repo.  They're actually mostly obsolete instructions.  The CMake building now takes care of the GitIdent and mod-script-pipe.  Languages should not be an issue if you are already set up with gettext.  The signing has been replaced by Notarization.  We no longer declutter the dmg, and no one has complained or commented about it on the forums.}}
  
Open a Terminal window and extract the wxWidgets source:
+
===Fetching The Manual===
  
:tar xf ~/Downloads/wxMac-2.8.12.tar
+
We have [[Building The Manual|instructions for fetching the manual]] on another page.
  
[[File:Bom wxwidgets 2812 extract.png|780px]]
 
  
Change to the newly created directory:
+
===Defaulting to Portable Settings===
  
:cd wxMac-2.8.12
+
<pre>
 +
1. Within audacity.app/Contents add the directories:
 +
    Portable Settings
 +
    Portable Settings/AutoSave
  
[[File:Bom wxwidgets 2812 cd.png|780px]]
+
2. Set permissions on these two directories to 777
 +
    chmod 777 "Portable Settings"
 +
    chmod 777 "Portable Settings/AutoSave"
 +
</pre>
  
Start the build. This assumes you downloaded the build_wxwidgets script to your Downloads directory:
+
These steps should of course be done before signing.
  
:sh ~/Downloads/build_wxwidgets
+
== Official Full Releases==
  
[[File:Bom wxwidgets 2812 build.png|780px]]
+
Official Audacity full releases:
  
After all configurations are built, you will be prompted for your password:
+
* Have a GitIdent, visible in the about box build information, that says what branch was used in building.
 +
* Include a copy of the manual.
 +
* Include other languages.
 +
* Have a de-cluttered .dmg (the folders in it are dragged outside the visible area)
 +
* Are signed with a signing key.
  
[[File:Bom wxwidgets 2812 install.png|780px]]
+
<s>
 +
===Updating GitIdent===
  
All configurations have been built and installed:
+
<pre>
 +
The Audacity "About" box can contain a link to the git commit at which
 +
Audacity was built. To create this, run this batch script in /mac/scripts/
 +
 +
  get_gitident.sh
 +
 +
If you do this, you are responsible for making sure the ident is correct
 +
in future builds.  The script overwrites RevisionIdent.h in the src directory.
 +
If you make further changes to your local copy after this step, or merge a
 +
more recent version from git, this file, and hence the ident in the build,
 +
stays the same, and so would be misleading.
 +
 +
To reset RevisionIdent.h you could do:
 +
 +
  git reset --hard origin/master
 +
</pre>
  
[[File:Bom wxwidgets 2812 complete.png|780px]]
+
===Include mod-script-pipe===
  
To verify, list the installed configurations:
+
Build this within the Xcode project ON THE SAME DAY as you built audacity.  You can click on the .so in the IDE to find out where Xcode put it (it will have some weird long temporary path).
  
[[File:Bom wxwidgets 2812 list.png|780px]]
+
Just before code signing, add it in to the Audacity bundle, into a subdirectory called 'modules'.
 +
</s>
  
Make sure you see 1 default configuration and 3 alternates:
+
===Include Languages===
  
[[File:Bom wxwidgets 2812 installed.png|780px]]
 
  
wxWidgets installation is now complete.
+
{{alert|1=Beware!  Audacity needs a clean and then a recompile if it is to include languages.<br>
 +
For some reason yet to be investigated, incremental compiles will not include the language files in audacity.app.<br>
 +
''(Check by looking inside the app and looking in 'Resources')''}}
  
== Building Audacity ==
+
<pre>
 +
If you need Audacity to show languages other than English, install the gettext
 +
suite of tools (to get the msgfmt command).  The source can be downloaded from:
  
Now that everything is in place, we finally get to the whole purpose of this exercise, building Audacity. But first, you must decide if you want to use the source for the current stable version of Audacity or if you want to get the absolute latest development source. Remember that the latter may not build (usually does) due to active development.
+
  ftp://ftp.gnu.org/gnu/gettext/gettext-latest.tar.gz
  
Make your choice when downloading from here:
+
Untar it:
  
:http://audacity.sourceforge.net/download/source
+
  tar xf gettext-latest.tar.gz
  
[[File:Bom audiacty_build_download.png|780px]]
+
And install:
  
Once you have the source downloaded and extracted, you may use either the xcodebuild command line utility or the Xcode 3.2.6 IDE.
+
  cd gexttext-latest
 +
  ./configure
 +
  sudo make install
  
The Audacity xcode project has 4 configurations defined:
+
Then clean and recompile.
 +
Incremental compiles will NOT include the language files.
  
:Debug Static - disables optimization, enables debugging code, and links to static libraries
+
</pre>
:Debug Shared - disables optimization, enables debugging code, and links to shared libraries
 
:Release Static - enables optimization, disables debugging code, and links to static libraries
 
:Release Shared - disables optimization, disables debugging code, and links to shared libraries
 
  
You'll need to select which one you want to use in the following steps, but "Debug Static" will be used for this guide.
+
<s>
 +
===Decluttering the dmg===
  
To use the command line utility, open a Terminal window, change to the Audacity mac directory, and start the build. If you didn't install Xcode 4.5.2 above, then use "xcodebuild" here:
+
<pre>
 +
  1. Open the dmg
  
:cd audacity/mac
+
2. Drag the right border wider.
:xcodebuild3 -configuration "Debug Static"
 
  
[[File:Bom audiacty_build_xcodebuild.png|780px]]
+
3. Drag all folders that should not be visible into that area.
  
When it completes, you should get a "Build Successful" message:
+
4. Drag right border narrower again.
 +
</pre>
 +
 
 +
 
 +
===Signing the DMG===
 +
 
 +
<pre>
 +
1) Comment out the last line of mac/scripts/build_dist.sh so that it reads
 +
 +
  #rm -rf ${DMG} TMP.dmg
 +
 +
  This will prevent deletion of TMP.dmg
 +
 
 +
2) Delete any previous /private/tmp/TMP.dmg and /private/tmp/Audacity.dst
 +
    (otherwise, the rebuilt plug-ins folder will contain an unnecessary duplicate
 +
    of itself).
 +
 
 +
    Then clean and build Audacity normally.
 +
 +
3) Navigate to /private/tmp/ and type
 +
 +
    hdiutil resize -size 200m TMP.dmg
 +
 +
    This step is needed as codesigning takes some temporary space, more than is
 +
    available in the dmg.
 +
 +
4) mount the dmg
 +
    hdiutil mount TMP.dmg
 +
 
 +
4a) Not part of the signing, but a good idea to de-clutter the dmg
 +
    per instructions in the section above.
 +
 +
5) Codesign the app (deep to make sure everything important is signed)
 +
   
 +
    codesign --deep -s <identity> -v "/Volumes/Audacity 2.2.0/Audacity.app"
 +
 
 +
    If you see errors like this, no matter what size you used in step (3):
 +
 
 +
        can't allocate code signature data for: /Volumes/Audacity 2.2.0/Audacity.app/Contents/MacOS/Audacity
 +
        (for architecture i386) because larger updated load commands do not fit (the program must be relinked
 +
        using a larger -headerpad value)
 +
 
 +
    Then in the XCode project, add -headerpad_max_install_names to Other Linker flags (OTHER_LDFLAGS)
 +
    for Release configuration of the Audacity target, and go back to step (2).
 +
 +
6) Check it is signed to gatekeeper's satisfaction:
 +
 +
    spctl -a -v "/Volumes/Audacity 2.2.0/Audacity.app"
 +
 +
7) unmount the dmg
 +
 
 +
    hdiutil eject "/Volumes/Audacity 2.2.0"
 +
 +
8) Make a compressed dmg
 +
 +
    hdiutil convert TMP.dmg -format UDZO -imagekey zlib-level=9 -o "Newname.dmg"
 +
 +
9) codesign that
 +
 +
    codesign -s <identity> -v Newname.dmg
 +

ToDo-2 Add
  • Instructions for building modules
These are instructions for building on Mac

The build family of pages:

Instructions in mac/build.txt

These instructions for building on mac are in mac/cmake_build.txt in the Git repo.
Instructions for building on macOS using CMake.

Building on macOS has been made much simpler with the Audacity 2.4.0
release. Still, read this document throughly before starting.

1) Get and install the latest Xcode version available your macOS version:

      MacOS                   Xcode Version (as of Mar 2020)
      Catalina - 10.15        11.3
      Mojave - 10.14          10.3
      High Sierra - 10.13     9.4.1
      Sierra - 10.12          9.2
      El Capitan - 10.11      8.2.1
      Yosemite - 10.10        7.2.1

2) Clone the Audacity repository:

      git clone https://github.com/audacity/audacity

3) Clone wxWidgets 3.1.3:

      git clone --recurse-submodules https://github.com/audacity/wxWidgets.git

   Ensure that you clone with the "--recurse-submodules" option, and do not
   just download the Zip package, otherwise there will be required components
   missing.

   Don't be tempted to use wxWidgets already installed by a package manager
   such as Homebrew because this will cause problems.

   We have applied some Audacity specific patches to wxWidgets to better 
   support VoiceOver, so please use the audacity-fixes-3.1.3 branch. It's
   the default branch on our GitHub copy:

      https://github.com/audacity/wxWidgets/tree/audacity-fixes-3.1.3

   You can be certain the correct branch is active with:

      git checkout audacity-fixes-3.1.3

4) Change directory to the folder where wxWidgets was cloned and build it using:

      sudo <path to Audacity source>/mac/scripts/build_wxwidgets

5) The config command should return "3.1.3" if the install was successful:

      /usr/local/x86_64/bin/wx-config --version

6) Now that you have wxWidgets installed, edit your ~/.bash_profile or
   ~/.zprofile and add:

      export WX_CONFIG=/usr/local/x86_64/bin/wx-config

   Log out and back in again (or reboot) for this to take effect.

7) Download the CMake 3.16.4 DMG from:

      https://cmake.org/download

8) Double click the DMG, follow the prompts and drag the CMake app to the
   Applications folder.

   If you will be building from the command line, open the CMake application
   and click the "Tools -> How to Install For Command Line Use" menu. It will
   give you additional instructions on making CMake available to the command
   line.

   You are now ready to start building Audacity.

BUILDING USING THE CMAKE GUI

   NOTE: Building with the GUI interface will result in the downloading of
         another copy of wxWidgets from Audacity.

1) Open the app.

2) Click the "Browse Source..." button and locate the top of your Audacity
   source tree, then click the "Open" button.

3) Click the "Browse Build..." button and find the location where you want to
   put the build (use the "New Folder" button at the bottom left to create a
   new folder).

   This folder does not have to be in or even near the source tree, but it
   must not be the same as the source tree. However, it is common to make it
   a subdirectory of the Audacity source tree.

4) Click the "Configure" button and when the dialog pops up, select "Xcode" for
   the generator, then click the "Done" button.

5) Click the "Generate" button to create the Xcode project.

6) Now you can either click the "Open Project" button or go to your "Build" folder in
   Finder and open the Xcode project as normal.

BUILDING FROM THE COMMAND LINE

1) Change directory to your Audacity source tree.

      cd audacity

2) Create the "build" folder (name it anything you like):

      mkdir bld

3) Change to the "build" folder:

      cd bld

4) Configure and generate the Xcode project:

      cmake -G Xcode ..

5) Build Audacity using the CMake command or xcodebuild:

      cmake --build . --config Release

      xcodebuild --configuration Release

   The "Audacity.app" bundle will be in the "bin/Release" subdirectory of your
   "build" folder, so you can start it via Finder or:

      open bin/Release/Audacity.app

Notes:

   - If you'd like to get a completely clean build, just delete "build" folder
     and return to step 2 above.

   - Once the Xcode project is generated, you shouldn't have to "configure" or
     "generate" again as it will be done for you automatically after pulling
     updates and building.

     For example:

        cd <audacity> directory
        git pull
        cd bld
        cmake --build . --config Release

   - Instructions on optional signing of DMGs, showing languages other than English,
     and other useful information can be found on our wiki at:

CMake Build

1) Change directory to your Audacity source tree.

      cd audacity

2) Create the "build" folder (name it anything you like):

      mkdir bld

3) Change to the "build" folder:

      cd bld

4) Configure and generate the Xcode project:

      cmake -G Xcode ..

5) Build Audacity using the CMake command or xcodebuild:

      cmake --build . --config Release

      xcodebuild --configuration Release

   The "Audacity.app" bundle will be in the "bin/Release" subdirectory of your
   "build" folder, so you can start it via Finder or:

      open bin/Release/Audacity.app

For a Release CMake build

Additionally:

6) Add the help files

   Open contents of bin/Release/Audacity.app
   Add in files with directory help/manual/ and then the 5 top level items

7) Notarize Audacity

   ../mac/scripts/build_dist.sh ../mac ../bld/bin/Release

For Notarization to work, you'll need to have already jumped through the Apple hoops, and have set up your signing file. There are two stages to notarization, one for the bundle, one for the dmg.

To test the Notarization, upload the dmg to dropbox and then download it again. Then double-click to install and drag across to /Applications. When you launch Audacity, you now get a warning about having downloaded from the internet, rather than being prevented from running...

Variations

These instructions for variations on building aren't in mac/build.txt in the Git repo. They're actually mostly obsolete instructions. The CMake building now takes care of the GitIdent and mod-script-pipe. Languages should not be an issue if you are already set up with gettext. The signing has been replaced by Notarization. We no longer declutter the dmg, and no one has complained or commented about it on the forums.

Fetching The Manual

We have instructions for fetching the manual on another page.


Defaulting to Portable Settings

 1. Within audacity.app/Contents add the directories:
    Portable Settings
    Portable Settings/AutoSave

 2. Set permissions on these two directories to 777
    chmod 777 "Portable Settings"
    chmod 777 "Portable Settings/AutoSave"

These steps should of course be done before signing.

Official Full Releases

Official Audacity full releases:

  • Have a GitIdent, visible in the about box build information, that says what branch was used in building.
  • Include a copy of the manual.
  • Include other languages.
  • Have a de-cluttered .dmg (the folders in it are dragged outside the visible area)
  • Are signed with a signing key.

Updating GitIdent

 The Audacity "About" box can contain a link to the git commit at which 
 Audacity was built. To create this, run this batch script in /mac/scripts/
 
   get_gitident.sh
 
 If you do this, you are responsible for making sure the ident is correct
 in future builds.  The script overwrites RevisionIdent.h in the src directory.
 If you make further changes to your local copy after this step, or merge a
 more recent version from git, this file, and hence the ident in the build, 
 stays the same, and so would be misleading.
 
 To reset RevisionIdent.h you could do:
 
   git reset --hard origin/master

Include mod-script-pipe

Build this within the Xcode project ON THE SAME DAY as you built audacity. You can click on the .so in the IDE to find out where Xcode put it (it will have some weird long temporary path).

Just before code signing, add it in to the Audacity bundle, into a subdirectory called 'modules'.

Include Languages

Warning icon Beware! Audacity needs a clean and then a recompile if it is to include languages.

For some reason yet to be investigated, incremental compiles will not include the language files in audacity.app.
(Check by looking inside the app and looking in 'Resources')

If you need Audacity to show languages other than English, install the gettext
suite of tools (to get the msgfmt command).  The source can be downloaded from:

   ftp://ftp.gnu.org/gnu/gettext/gettext-latest.tar.gz

Untar it:

   tar xf gettext-latest.tar.gz

And install:

   cd gexttext-latest
   ./configure
   sudo make install

Then clean and recompile.
Incremental compiles will NOT include the language files.

Decluttering the dmg

 1. Open the dmg

 2. Drag the right border wider.

 3. Drag all folders that should not be visible into that area.

 4. Drag right border narrower again.


Signing the DMG

 1) Comment out the last line of mac/scripts/build_dist.sh so that it reads
 
   #rm -rf ${DMG} TMP.dmg
 
   This will prevent deletion of TMP.dmg

 2) Delete any previous /private/tmp/TMP.dmg and /private/tmp/Audacity.dst
    (otherwise, the rebuilt plug-ins folder will contain an unnecessary duplicate
    of itself).

    Then clean and build Audacity normally.
 
 3) Navigate to /private/tmp/ and type 
 
    hdiutil resize -size 200m TMP.dmg
 
    This step is needed as codesigning takes some temporary space, more than is 
    available in the dmg.
 
 4) mount the dmg
    hdiutil mount TMP.dmg

 4a) Not part of the signing, but a good idea to de-clutter the dmg
    per instructions in the section above.
 
 5) Codesign the app (deep to make sure everything important is signed)
     
    codesign --deep -s <identity> -v "/Volumes/Audacity 2.2.0/Audacity.app"

    If you see errors like this, no matter what size you used in step (3):

        can't allocate code signature data for: /Volumes/Audacity 2.2.0/Audacity.app/Contents/MacOS/Audacity
        (for architecture i386) because larger updated load commands do not fit (the program must be relinked
        using a larger -headerpad value)

    Then in the XCode project, add -headerpad_max_install_names to Other Linker flags (OTHER_LDFLAGS)
    for Release configuration of the Audacity target, and go back to step (2).
 
 6) Check it is signed to gatekeeper's satisfaction:
 
    spctl -a -v "/Volumes/Audacity 2.2.0/Audacity.app"
 
 7) unmount the dmg

    hdiutil eject "/Volumes/Audacity 2.2.0"
 
 8) Make a compressed dmg
 
    hdiutil convert TMP.dmg -format UDZO -imagekey zlib-level=9 -o "Newname.dmg"
 
 9) codesign that
 
    codesign -s <identity> -v Newname.dmg
