failled to build ldc 1.15.0 with llvm/8.0.0 and clang++ #3063

Closed bioinfornatics closed 5 years ago

bioinfornatics commented 5 years ago

Dear,

I installed LLVM/8.0.0 with clang++ and tried to build ldc2.

But the phobos compilation imply a segmentation fault from ldc2

Did you build LLVM 8.0.0 yourself? With which clang version? And did you use the same clang version when compiling LDC? - I'm asking because the clang team f*cked up badly with clang v7.0.x (ABI bug, fixed in 8.x and 7.1.x).

bioinfornatics commented 5 years ago

Thanks @kinke for your quick answer. I am using LLVM 8.0.0 built myself. I think the problem comes from LLVM itself and not the ldc build procedure. So I will close this ticket and I will come back if I get more information.

Thanks and have a nice day

@kinke did you try to build this ldc release with llvm8 and clang?

kinke commented 5 years ago

All of our latest prebuilt packages ship with LLVM 8.0.0. clang (v8.0.0) is used for the prebuilt Windows packages (LLVM + LDC), and the macOS packages use AppleClang v10.0.0. The Linux packages use gcc.
