Ok, so the libs are supposed to be under /usr/lib64. Just wanted to make sure.
I have both 32 and 64-bit packages for llvm and devel files installed.
/usr/lib64/llvm contains: BugpointPasses.so libclang.so, libLLVM-3.3.so,
libLTO.so, libprofile_rt.so, and LLVMgold.so.
No *.a files there? After an installation of LLVM 3.3 from source I
get a bunch of static libraries along with libLLVM-3.3.so, and I guess
that these are what llvm-config --libs lists. If you have the -devel
packages installed then you should have these as well, if LLVM is
properly packaged on Fedora, and then the linker would be able to find
those libraries, too. It certainly does on my Arch system. Maybe the
static libraries are in a separate package?
Anyway, since you have libLLVM-3.3.so, that's all you need to link
against. You just need to fix up the linker command in the Makefile
accordingly. Here's how the corresponding target in
compiler/Makefile.unix (line 83) should look like in your case:
faust : $(objects) main.o libmain.o global.o scheduler.ll
$(CXX) $(CXXFLAGS) $(objects) main.o libmain.o global.o
`$(LLVM_CONFIG) --ldflags` -lLLVM-3.3 -ldl -o faust
Or try the patch against Makefile.unix attached to this post. This
should work whenever the shared LLVM lib is installed. Just tried this
over here (using LLVM 3.4, however) and it seems to work fine.
Stephane, I'd suggest to have the Makefile check for a shared LLVM lib
before relying on `llvm-config --libs`. The attached patch against
Makefile.unix does the trick for me. Ok to commit? (You should first
give this a whirl on OS X, though, to see if it works there as well.)
HTH,
Albert
