[llvm-dev] Compile issues with LLVM ORC JIT

Tue Aug 8 00:40:26 PDT 2017

Hi Ingmar

What version of LLVM are you building against?
Did you try building the original example from the LLVM sources in
llvm/examples/Kaleidoscope/BuildingAJIT/Chapter3?

There's quite a few differences actually (namespaces, class name,
include guard).

Did you configure your LLVM build with LLVM_ENABLE_CXX1Y=ON? It's
probably not the issue here, but sticking to one set of compile options
for all parts of a project saves headache.

That's two times the same ;)

If you are not sure about your toolchain configuration, did you consider
using CMake?
