Msbuild: Building msbuild for mono built from source fails

[ratstache]

Problem

When building msbuild targeting mono built from source fails. Here is the error I got when trying to do this with all the dotnet prerequisites installed.

packages/Microsoft.DotNet.BuildTools/1.0.27-prerelease-00927-05/lib/tool-runtime/project.lock.json(1,0): warning NU1006: Dependencies in project.json were modified. Please run "dotnet restore" to generate a new lock file.
Done initializing tools.

That error doesn't fail the build but it's the first indication that something is not right. adding a dotnet restore command in the script didn't fix the issue either.

I will add the entire error output tomorrow when I'm back on my main computer, just wanted to log this now.

Did you set CscToolPath? I assume you have mono in PATH? And is that a recent one, with $mono_prefix/lib/mono/4.5/csc.exe ?

[ratstache]

yeah, csc.exe is in the location you specified, mono is in the PATH, but I did not set CscToolPath. Just set that to the location of the csc.exe?

Anything new on this?

Is there any solutions on this. I know, I know, this is not how I’m supposed to do it, but I can't think of something better. This is where it all begins...
