[LLVMdev] Kaleidoscope-tutorial: Fails to create the JIT

[Garrison Venn]

Change your g++ build to:

g++ -g -O0 toy-example26.cpp -o toy-example26  `/Users/albert/NoTimeMachine/LLCM_Clang/llvm-trunk/BUILD/Debug/bin/llvm-config --cppflags --ldflags --libs core jit interpreter native`

After you get this working, try it with the source interpreter include removed, and minus the above interpreter llvm-config addition.
