neoeinstein/mono-llvm repository overview

⁠LLVM-enabled Mono (C#) Docker image

This image is based on the debian:jessie⁠ image and contains Mono⁠ compiled with LLVM integration enabled.

Total size of this image is:

⁠Notes

By default, the mono executable does not use the LLVM backend. You can enforce the use of LLVM by using the --llvm argument when invoking mono or by setting the MONO_USE_LLVM environment variable as in the below example.

If you would like to AOT-compile the Global Assembly Cache, execute /usr/local/bin/mono-gac-aot. This script will use the LLVM backend and attempt to perform a full Ahead-Of-Time compilation of mscorlib.dll and all assemblies in the GAC. This can take some time, and will likely compile several assemblies that you may not need, though you can follow its pattern to execute a targeted compilation of assemblies.

In order to save image space, the bugpoint, monodis, and mono-boehm executables have been removed from the installation.

⁠Usage Example

$ echo 'using System; class MainClass { public static void Main (string[] args) { Console.WriteLine ("Hello World from LLVM!"); } }' > qq.mono
$ docker run --rm -e MONO_USE_LLVM=1 -v "$(pwd)":/mnt neoeinstein/mono-llvm sh -c "mcs -out:/mnt/qq.exe /mnt/qq.mono && mono /mnt/qq.exe"

Once you have run these commands you will have qq.exe mono-executable in your current directory, and you will get printed 'Hello World from LLVM!' on Mono!
