Priority: medium Bug ID: 75929 Assignee: dri-devel@lists.freedesktop.org Summary: Configuring Mesa to use shared libLLVM.so fails Severity: normal Classification: Unclassified OS: Linux (All) Reporter: rankincj@googlemail.com Hardware: x86-64 (AMD64) Status: NEW Version: git Component: Drivers/Gallium/r600 Product: Mesa
Created attachment 95379 --> https://bugs.freedesktop.org/attachment.cgi?id=95379&action=edit 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.

--- Comment #1 from Emil Velikov emil.l.velikov@gmail.com --- 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.

--- Comment #2 from Dave Witbrodt dawitbro@sbcglobal.net --- 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 (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.)

--- Comment #3 from Emil Velikov emil.l.velikov@gmail.com --- 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.

--- Comment #4 from Dave Witbrodt dawitbro@sbcglobal.net --- 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.
