<pre>The change in <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - [CMake] Do not use LLVM static libraries for FTL JIT"
href="show_bug.cgi?id=151559">bug #151559</a> doesn't work for current versions of llvm on all platforms, and it won't work on platforms that don't use the .so file extension (eg: OS X and Windows)
The macro is doing:
set(LLVM_SONAME "LLVM-${LLVM_VERSION}")
if (EXISTS "${LLVM_LIBS_DIRECTORY}/lib${LLVM_SONAME}.so")
set(LLVM_LIBRARIES "${LLVM_LDFLAGS} -l${LLVM_SONAME}")
else ()
set(LLVM_LIBRARIES "${LLVM_LDFLAGS} ${LLVM_LIBS}")
endif ()
Recent versions of llvm don't include "-${LLVM_VERSION}" in the name of the library.
On OS X, the library is named libLLVM-${LLVM_VERSION}.dylib for llvm 3.7 and earlier and libLLVM.dylib for llvm 3.8 (release_38 branch) and 3.9 (trunk).
I suspect the library is named libLLVM.so on Linux and BSD for llvm 3.8 and later.</pre>
