Description Ting-Wei Lan 2015-12-07 22:28:37 UTC
'llvm-config37 --libfiles' command shows a lot of .a files, but none of them exist, which causes build failure for WebKitGTK+ 2.11.2.

gmake[2]: *** No rule to make target '/usr/local/llvm37/lib/libLLVMSupport.a', needed by 'DerivedSources/JavaScriptCore/WebKitLLVMLibraryToken.h'.  Stop.
CMakeFiles/Makefile2:485: recipe for target 'Source/JavaScriptCore/CMakeFiles/llvmForJSC.dir/all' failed

Can we get these .a files in llvm37 package?
Comment 1 Brooks Davis freebsd_committer 2015-12-08 12:37:38 UTC
I looked into this.  It's possible to do so by disabling BUILD_SHARED_LIBS, but it makes the package really big (on disk >900MB vs < 200MB).  It also gets rid of the shared libraries so I'm disinclined to enable this.  We could potentially add an llvm36-staticlibs that only installs the static libraries, but that seems a bit hawkish and hard to maintain.

Copy bits from https://bugs.gentoo.org/show_bug.cgi?id=565358 to make llvm-config37 --system-libs .so files instead of .a.

I think upstream should fix this propperly.

I don't think it a good idea to wipe system-libs like the above bug mentions, since is might break other ports. I should note that no released beignet version supports llvm 3.7 yet.
