Building SV v3.1 on Windows¶

Versions 3.0+ of Sonic Visualiser are primarily 64-bit for Windows, although the 32-bit version is still supported.

• Both builds can be run from Qt Creator, or from a command prompt using batch build scripts provided.

• The 64-bit version is built using the Microsoft Visual C++ compiler. Install 64-bit Microsoft Visual Studio 2017 Community Edition and then Qt 5.11 (or latest 5.x).

• The 32-bit version is built using the MinGW compiler. Install Qt 5.11 (or latest 5.x) with Qt Creator and ensure that the 32-bit MinGW option is available.

• The official 64-bit installer also includes some helper binaries from the 32-bit build, enabling it to use 32-bit Vamp plugins as well as 64-bit ones. So to make our official 64-bit installer, we actually have to complete both builds.

• The installers are built using WiX, so you must have that installed. The path to WiX is hardcoded in our script and at the time of writing it assumes WiX v3.11.

• We use the Repoint source dependency manager. Ensure the required SML runtime for this is available (either SML/NJ or Poly/ML), and then run .\repoint install in a command prompt or Powershell window before opening a build project or starting a build.

In both cases (32 and 64 bit) the dependent libraries we use are found in the sv-dependency-builds subrepo. Prior to the switch to using the Repoint dependency manager, this subrepo was checked out by Mercurial as a matter of course with the SV repo; after the switch to Repoint, it is one of the library modules that is installed by running .\repoint install. There should be no other external dependencies besides Qt and the runtime libraries it needs.

Which SV branch to use¶

Use the default branch of the SV Mercurial repo unless you have a particular reason to know otherwise.

32-bit build and installer¶

Build¶

This process is similar to that introduced in v2.1 (see WindowsBuild21), except that we now do use a shadow build.

• Check out the correct branch (probably default as described above)
• Run ./vext install to get the code dependencies
• Open the main sonic-visualiser.pro project in Qt Creator
• Set up a release build using Desktop Qt 5.7.0 MinGW 32-bit as a shadow build
• "Run qmake" and "Rebuild All"

There is still one unresolved manual step before you can run Sonic Visualiser:

• Go to the build directory (e.g. build-sonic-visualiser-Desktop_Qt_5_7_0_MinGW_32bit-Release) and copy the file checker\release\vamp-plugin-load-checker.exe to the top-level release directory

If the build was successful, you should now be able to run Sonic Visualiser from within the IDE. (You can't yet run the binary from the Windows Explorer, as Qt and other dependencies won't be found.)

You can also run individual unit test suites by selecting them as target executable in Qt Creator.

Installer¶

The principle here is:

1. Copy dependent libraries into the release directory within the build dir, so that Sonic Visualiser can be run directly without IDE support
2. Package up the installer using the build.cmd script that runs WiX

For the Qt 5.7 installation I'm currently using, this means:

• From C:\Qt57\5.7\mingw53_32\bin, copy the following files into the release directory: Qt5Core.dll Qt5Gui.dll Qt5Network.dll Qt5Svg.dll Qt5Widgets.dll Qt5Xml.dll libgcc_s_dw2-1.dll libstdc++-6.dll libwinpthread-1.dll
• From C:\Qt57\5.7\mingw53_32\plugins\platforms, copy the following files: qminimal.dll qwindows.dll
• Check that the Sonic Visualiser executable in that directory starts up properly when double-clicked
• In a command prompt window, cd to the deploy\win32 directory in the Sonic Visualiser source tree and run .\build.cmd

Note that the build.cmd script has the path to the shadow build folder hardcoded, so you may need to tweak that.

64-bit build and installer¶

Build¶

• Check out the correct branch (probably default as described above)
• Run ./vext install to get the code dependencies
• Open the main sonic-visualiser.pro project in Qt Creator
• Set up a release build using Desktop Qt 5.7.0 MSVC 64-bit as a shadow build
• "Run qmake" and "Rebuild All"

If the code is already checked out for a 32-bit build, then it should be possible to add or select the 64-bit MSVC "kit" as a target in Qt Creator and then build that from the same directory as a separate shadow build, rather than having to check out the code again.

And we have the same unresolved manual step as for the 32-bit build:

• Go to the build directory (e.g. build-sonic-visualiser-Desktop_Qt_5_7_0_MSVC2015_64bit-Release) and copy the file checker\release\vamp-plugin-load-checker.exe to the top-level release directory

If the build was successful, you should now be able to run Sonic Visualiser from within the IDE. (You can't yet run the binary from the Windows Explorer, as Qt and other dependencies won't be found.)

You can also run individual unit test suites by selecting them as target executable in Qt Creator.

Installer¶

The 64-bit installer needs files from both the 64- and 32-bit builds.

The principle is:

1. Copy dependent 64-bit libraries into the release directory within the build dir, so that Sonic Visualiser can be run directly without IDE support
2. Copy helper programs from the 32-bit build into the release directory, renaming them to have -32 at the ends of their names
3. Copy (the smaller number of) dependent 32-bit libraries that the 32-bit helper programs need into the release directory
4. Package up the installer using the build.cmd script that runs WiX

For the Qt 5.7 installation I'm currently using, this means:

• From C:\Qt57\5.7\msvc2015_64\bin, copy the following files into the release directory: Qt5Core.dll Qt5Gui.dll Qt5Network.dll Qt5Svg.dll Qt5Widgets.dll Qt5Xml.dll
• From C:\Qt57\5.7\msvc2015_64\plugins\platforms, copy the following files: qminimal.dll qwindows.dll
• From the 32-bit build's release directory, copy the files vamp-plugin-load-checker.exe and piper-vamp-simple-server.exe, renaming them to vamp-plugin-load-checker-32.exe and piper-vamp-simple-server-32.exe respectively (so as not to overwrite the existing 64-bit versions of these files)
• From C:\Qt57\5.7\mingw53_32\bin, copy: libgcc_s_dw2-1.dll libstdc++-6.dll libwinpthread-1.dll
• (From the SV build directory's sv-dependency-builds/win64/lib directory: copy libsndfile-1.dll -- this is technically optional as the installer script will include it regardless, but it's necessary if you want to test SV by double-clicking)
• Check that the Sonic Visualiser executable in that directory starts up properly when double-clicked
• In a command prompt window, cd to the deploy\win64 directory in the Sonic Visualiser source tree and run .\build.cmd

Note that the build.cmd script has the path to the shadow build folder hardcoded, so you may need to tweak that. The WiX installer config file (sonic-visualiser.wxs) also has some hardcoded paths, for the Microsoft Visual Studio runtime libraries in C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\redist\x64\Microsoft.VC140.CRT, which may need to be updated.
