What does this mean, and how to fix it

I'm trying to compile a snex wave shaper to dll, and this error message pops up.

The following build commands failed:
	CompileC /Users/ulrikboden/Music/Hise/HISE\ PROJECTS/EGNA/FX/FX\ Lanes/DspNetworks/Binaries/Builds/MacOSX/build/FX\ Lanes.build/Release/FX\ Lanes\ -\ Dynamic\ Library.build/Objects-normal/arm64/Main.o /Users/ulrikboden/Music/Hise/HISE\ PROJECTS/EGNA/FX/FX\ Lanes/DspNetworks/Binaries/Source/Main.cpp normal arm64 c++ com.apple.compilers.llvm.clang.1_0.compiler (in target 'FX Lanes - Dynamic Library' from project 'FX Lanes')
(1 failure)

Anybody knows what it means and how to fix it?
