So I've been trying to debug this on my own for a few days now and just feel like giving up right now.
I have uninstall Mono-Complete, Mono-Devel, reinstalled both, attempted to locate MSBuild on its own but was told that was a bad idea, and am now stuck.
I am attempting to compile Ultimate DOOM Builder from source, as the Windows version is running horrendously under Wine and Proton (through Steam). Each time I try I am met with this error:
msbuild /nologo /verbosity:minimal -p:Configuration=Release BuilderMono.slnmake: msbuild: No such file or directorymake: *** [Makefile:14: builder] Error 127
msbuild /nologo /verbosity:minimal -p:Configuration=Release BuilderMono.slnmake: msbuild: No such file or directorymake: *** [Makefile:14: builder] Error 127
If anyone could tell me what I've done wrong or what I've missed, I beg you, please do. Thank you in advanced.
