It's now failing with -lLLVM_3.3svn. I was looking for where the llvm
version stuff was read in the Makefiles. I decided against that and I
tried rebuilding llvm again, modifying the cmake package version in
the llvm sources to be set to 3.3 instead of 3.3svn.
That got the compile to work with the Makefiles unmodified (with the
exception of changing LLVM_CLANG to use CXX). However, I still get an
error with -lLLVM_3.3 not found. I realized that's due to llvm
building static libs. I modified compiler/Makefile.unix to use
`$(LLVM_CONFIG) --libs` instead of -lLLVM-`$(LLVM_CONFIG) --version`
that it would just statically compile in llvm into libfaust.dylib.
Note: it seems compiling with system clang instead of LLVM_CLANG
compiled alright.
Other notes: LLVM doesn't build shared libs when building from source
by default. LLVM's documentation for Cmake mentions:
Flag indicating is shared libraries will be built. Its default value is
OFF. Shared libraries are not supported on Windows and not recommended in the
other OSes.
