Hi Chris I have a similar patch [1] which also clears up the remaining messages. It's queued up and I'm planning to commit it shortly. Thanks for the heads up. [1] http://lists.freedesktop.org/archives/mesa-dev/2014-March/055316.html I've been having lots of trouble building Mesa for RadeonSI with recent LLVM 3.5 snapshots. I am happy to report that applying Emil's patch from comment 1, in combination with attachment 95368 [details] (from bug 75919), gets everything working for me again. (Without 95368, I get static linkage to LLVM instead of shared, which is comical since my build errors out unless I use the "--enable-llvm-shared-libs" config option.) Just committed the patch to master, so one should be able to enable/disable the option on demand. AFAICS one could do some clean-up wrt LLVM handling in configure.ac although I'd rather leave that to someone more experienced in that area. Emil's patch (now applied in Mesa 9.2.0-devel), along with an LLVM 3.5 build with the proper symlinks (bug 75919), nearly allows me to build Mesa for RadeonSI. In my scrambling about to get the build working again, I forgot that I also had to apply a patch from bug 70410 to get the build working. Anyway, glad to see this bug closed. |

Created attachment 95379 [details] Patch for configure.ac to fix building against libLLVM.so Configuring Mesa to build on Fedora 20 with the shared libLLVM.so is ignoring the new --enable-llvm-shared-libs option. It looks like two references to "with_llvm_shared_libs" were missed in configure.ac. I have attached a patch.
