Instructions for building on Windows. Fuller instructions that include * Portable Settings * Building an Installer can be found on our wiki at http://wiki.audacityteam.org/wiki/Building_On_Windows 1. MSVC 2017: Download and install Microsoft Visual Studio 2017 https://docs.microsoft.com/en-us/visualstudio/install/install-visual-studio?view=vs-2017 2. Git: Download and install Git, for example by installing: Git for Windows: https://git-scm.com/download/win and optionally GitExtensions: http://gitextensions.github.io/ download and run the .msi installer. GitExtensions has a GUI interface, includes Git for Windows and has a Git bash command line in the bottom panel of the screen. 3. wxWidgets: 1) Clone wxWidgets and checkout 3.1.1 from the Audacity fork of the wxWidgets project: https://github.com/audacity/wxWidgets/ for example, in the git-bash command line mkdir ./wxWidgets cd ./wxWidgets git clone --recurse-submodules https://github.com/audacity/wxWidgets/ IF you forgot the --recurse-submodules, you can correct that later by: git submodule update --init 2) Follow instructions for building at https://github.com/audacity/wxWidgets/blob/v3.1.1/README-GIT.md https://github.com/audacity/wxWidgets/blob/v3.1.1/docs/msw/install.txt DO set WXWIN to the appropriate directory where you installed wxWidgets. To do that, open a cmd.exe window, and type: set WXWIN=C:\wxWidgets-3.1.1 You will be building a dll version with MSVC2017 IDE, so... In MSVC 2017 open wx_vc15.sln, and select dll, release. Then build. 3) Having got this far, it is well worth trying out building some wxWidgets examples to confirm that building has worked OK 4. Audacity 1) Clone Audacity from the Audacity GitHub project. https://github.com/audacity/audacity/ for example, in the git-bash command line mkdir ./audacity cd ./audacity git clone https://github.com/audacity/audacity/ Audacity itself does not use/need git submodules. 2) in MSVC 2017 open audacity.sln Choose Release or Debug. Click compile.
Defaulting to Portable Settings
UH? These instructions are for Mac. 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"
Some functionality in Audacity is currently turned on in its default configuration, but requires that extra libraries be downloaded separately to use it. To change the libraries enabled in Audacity, edit "win\configwin.h" and comment or uncomment the entries. You might also try modifying the features enabled in "src\experiemntal.h"
ASIO (from Steinberg) is a sound card interface protocol that is faster than standard WMME. Unlike WMME, not all soundcard drivers support it. Because ASIO is a proprietary, closed standard, we (or any third party) cannot distribute its SDK. That means we cannot distribute builds of Audacity that support ASIO, because Audacity is licensed under the GPL (http://audacityteam.org/about/license), which requires we distribute all source code. So, although you can build your own copies of Audacity with ASIO support, for personal use, you cannot distribute them without violating the Audacity license and the ASIO license. If you build ASIO support into Audacity, do not distribute that build. For ASIO support, get the ASIO SDK from Steinberg (http://www.steinberg.net/en/company/developers.html), install at C:\ASIOSDK, then define an environment variable called ASIOSDK_DIR. The value should be the full path to the base directory of the ASIO SDK, e.g., set ASIOSDK_DIR=C:\ASIOSDK
Official Full Releases
Official full releases:
- Have a GitIdent, visible in the about box build information, that says what branch was used in building.
- Come with translations
- May be as a zip file
- No manual provided
- May be as a windows installer.
- These come with help files in html format.
- Are signed.
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/ using the git-bash command line bash 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
Fetching The Manual
We have instructions for fetching the manual on another page.
1. In the MSVC project, click on 'locale' project and build.
1. Open the "gl_ES", "ko_KR" and "pt" folders in turn and move the "wxstd.mo" file in each to the "gl", "ko" and pt_PT folders respectively. 2. Delete the "gl_ES", ko_KR and "pt" folders. 3. COPY (do not move) wxstd.mo from "eu" into "eu_ES".
Building the Installer
The Inno setup installer requires certain files in certain places to be able to produce the installer.
1. Copy msvcp140.dll and vcruntime140.dll from C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Redist\MSVC\14.14.26405\x86\Microsoft.VC141.CRT to \win\release The 64 bit version will not work on 32 bit machines.
Now to actually make the installer...
1. Install the latest Unicode Inno Setup (http://www.jrsoftware.org/isinfo.php). 2. Open the Inno Setup script: \win\audacity.iss 3. Click 'Compile'.
Making the Zip File
Do this step after making and testing the installer.
Having installed from the installer 1. Use 7-zip to create a new archive from the installed files excluding: - The manual - The unins* files - FirstTimeInit.txt
Note that the .exe in this zip file and dlls are not code signed. Audacity loads dlls dynamically at run time, possibly unsigned ones, so signing the exe itself is misleading for security. The integrity and security of the zip file is provided by its published checksukm. The situation is different for the installer where the code signature protects the entire bundle.
Signing the Installer
Codesigning uses a USB dongle (smart card reader) and a timestamp server at certum:
signtool sign /n "James Crook" /t http://time.certum.pl/ /fd sha256 /v <path-to-audacity-git>\win\Output\audacity-win-2.3.0.exe
