(More details at comment 2 of bug 75929.)

It > searches for a libLLVM-3.5.0.so but only libLLVM-3.5.so exists. Are you using cmake or autoconf to build LLVM? I use autoconf and on my system llvm-config --version reports 3.5.0 and llvm install libLLVM-3.5.0.so and also a symlink from libLLVM-3.5.0.so to libLLV-3.5.so.

I use packages from: http://llvm.org/apt/unstable/pool/main/l/llvm-toolchain-snapshot/ After a short look into it, I think that there is a small bug in it. One package populates link farm in usr/lib/llvm-3.5/lib/ and while it links usr/lib/@DEB_HOST_MULTIARCH@/libLLVM-3.5.so.1 usr/lib/llvm-3.5/lib/libLLVM-3.5.so it doesn't do the same for 3.5.0 variant. Mystery solved, time to poke the maintainer. It should be fixed soon. (In reply to comment #4) LLVM 3.5 packages for Debian at llvm.org/apt have been fixed for about a week. Looks like I need a patch from bug 70410 to build Mesa for RadeonSI, though. |

Created attachment 95368 [details] Is there even a point? llvm-config-3.5 --version now prints 3.5.0 instead of 3.5. config is unable to find a shared llvm library if there is only one so. It searches for a libLLVM-3.5.0.so but only libLLVM-3.5.so exists.
