Question

Dub assumes default installation path for LLVM on Windows

GoaLitiuM opened this issue 5 years ago · comments

Building dstep on Windows fails when LLVM is installed to somewhere else than the default installation directory.

The build instructions should be corrected for Windows builds as there seems to be no attemps to discover where the LLVM is installed, it is only assumed to be installed under C:\Program Files\LLVM (which is also a hardcoded path, "/LIBPATH:$PROGRAMFILES\\LLVM\\lib" should be used instead for lflags-windows).

I can't get $PROGRAMFILES to work. It contains spaces and the linker doesn't seem to like that: https://ci.appveyor.com/project/jacob-carlborg/dstep/build/job/d75tsc612x7sb2aj.

It seems to be a bug in DMD, LDC passes the fully quoted LIBPATH to linker just fine, but DMD seems to drop them somewhere in the way.

I reported a bug: https://issues.dlang.org/show_bug.cgi?id=19821.

There was actually an existing report about the same bug dated few years back: https://issues.dlang.org/show_bug.cgi?id=16677

I could use $PROGRAMFILES for LDC, if that's useful?

I think the mention about the installation path in README should be enough for now, until the bug gets fixed in DMD.
