I tried to install =dev-lang/ispc-1.9.2, which failed with error reported in bug #652442 and bug #656632. Therefore, I was trying to use the live ebuild to install it, but first got a compile error on an invalid conversion from int to enum, which I could patch, but then it failed with a linker error with undefined references to llvm::{Value,Module}::dump.

Searching for this issue, I found a question on https://stackoverflow.com/questions/46367910/llvm-5-0-linking-error-with-llvmmoduledump# which states, this is due to llvm compiled in release mode. I then tried to compile llvm:6[debug], which didn't succeed.

After reporting the issue upstream at https://github.com/ispc/ispc/issues/1355 I tried using clang to compile the package, which didn't work out for clang:6, getting the very same linker error. Following their advice, I then installed clang:5[debug] and llvm:5[debug] which finished building, after adapting the ebuild to use them.



$ emerge -pqv =dev-lang/ispc-9999::gentoo
[ebuild   R   ] dev-lang/ispc-9999 [9999] USE="examples"

Patch to resolve gcc compile error.

[Comment 5 Bernd 2018-11-17 07:37:23 UTC]

Upstream has included https://bugs.gentoo.org/attachment.cgi?id=554452 into the sources. The package compiles fine against gcc now.
After having successfully installed llvm:6[debug] and clang:6[debug] it also compiles against them.

So this bug can be closed.
