The Windows page may have more information: see Build Instructions with Mono

• Run \Setup\BuildInstallers.Mono.cmd

Mono 4.4.0 or later is required, because it uses C# 4.6.1 compiler by default. Refer to Git Extensions on Linux for details on how to build and debug on Linux.

Not all image formats are supported on Mono. PNG images with a color depth of 48 bpp will cause compiler errors. If you run into this problem you should convert all PNG images to 8 bpp.

This can be done using the following Linux commands:

sudo apt-get install imagemagick
mogrify -depth 8 $(find -iname '*.png')
mogrify -depth 8 $(find -iname '*.PNG')

Tests use NUnit under Mono.

• openSUSE: http://software.opensuse.org/package/GitExtensions
  • which is currently fed by https://build.opensuse.org/package/show/home:codeminister/GitExtensions.

macOS Mono support for Git Extensions is unknown.

Note specifically though that you at least in 5.4 must run tMono in 32bit version as the 64bit WinForm support is incomplete. Start with --arch=32. http://www.mono-project.com/docs/about-mono/supported-platforms/osx/
