I'd rather avoid updating my OS at the moment or setting up a VM. But the cmake comments were a hint.. I suspect something is going wrong in there preventing it from adding the actual library files to the linker commandline. I added this to my CMakeLists.txt: set(CMAKE_VERBOSE_MAKEFILE on) Which shows no LLVM libs at all being passed in: [ 8%] Linking CXX executable ../bin/CBreakCompiler /usr/bin/c++ CMakeFiles/CBreakCompiler.dir/src/main.cpp.o CMakeFiles/CBreakCompiler.dir/src/Parser.cpp.o CMakeFiles/CBreakCompiler.dir/src/SourceTokenizer.cpp.o CMakeFiles/CBreakCompiler.dir/src/IRCompiler.cpp.o CMakeFiles/CBreakCompiler.dir/src/CompiledOutput.cpp.o CMakeFiles/CBreakCompiler.dir/src/JIT.cpp.o -o ../bin/CBreakCompiler If I change this: llvm_map_components_to_libnames(llvm_libs all) to: llvm_map_components_to_libnames(llvm_libs core) Then I start to see libraries being added: [ 8%] Linking CXX executable ../bin/CBreakCompiler /usr/bin/c++ CMakeFiles/CBreakCompiler.dir/src/main.cpp.o CMakeFiles/CBreakCompiler.dir/src/Parser.cpp.o CMakeFiles/CBreakCompiler.dir/src/SourceTokenizer.cpp.o CMakeFiles/CBreakCompiler.dir/src/IRCompiler.cpp.o CMakeFiles/CBreakCompiler.dir/src/CompiledOutput.cpp.o CMakeFiles/CBreakCompiler.dir/src/JIT.cpp.o -o ../bin/CBreakCompiler /usr/local/lib/libLLVMCore.a /usr/local/lib/libLLVMBinaryFormat.a /usr/local/lib/libLLVMRemarks.a /usr/local/lib/libLLVMBitstreamReader.a /usr/local/lib/libLLVMSupport.a -lrt -ldl -ltinfo -lpthread -lm /usr/local/lib/libLLVMDemangle.a Perhaps I can figure out which ones I need and manually specify them all, rather than using "all".

I've managed to get 10.0.0 working now.. there were a couple things I had
to adjust.
The Kaleidoscope example had me doing this before creating the object file:
llvm::InitializeAllTargetInfos();
llvm::InitializeAllTargets();
llvm::InitializeAllTargetMCs();
llvm::InitializeAllAsmParsers();
llvm::InitializeAllAsmPrinters();
It turns out I can get away with just this, since I'm not (yet) worried
about targeting other machines:
llvm::InitializeNativeTarget();
llvm::InitializeNativeTargetAsmPrinter();
Since "all" doesn't work anymore for some reason, I've managed
to (through
trial and error, guessing at different names shown from llvm-config
--components) end up with this set of libnames:
llvm_map_components_to_libnames(llvm_libs core executionengine support
nativecodegen)
That left me with 2 link errors referring to llvm::raw_ostream and
llvm::raw_pwrite_stream. After much more digging through similar
complaints on the internet.. the last fix turned out to be adding this to
CMakeLists.txt:
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fno-rtti")
I am a little worried that the rtti flag may come back and bite me later
when I get around to building this on windows again (since I do use
exceptions), but that's a problem for another day.
One last question.. is there a good way to know which libnames I need,
based on which #includes I pull in or which classes I'm using? I didn't
see anything obvious in the doxygen documentation.
