[LLVMdev] Getting Kaleidoscope to compile

[Russell Wallace]

Hi all,

I've started work on a new programming language for which I am
considering using LLVM as the backend,  and trying to experiment with
it using the Kaleidoscope demo compiler.

Taking the full source listing from
http://llvm.org/docs/tutorial/LangImpl3.html#code and trying to
compile it with the provided instructions gives me the following
errors:

a at a-desktop:~$ g++ -g -O3 toy.cpp `llvm-config --cppflags --ldflags
--libs core` -o toy
toy.cpp:5:30: error: llvm/LLVMContext.h: No such file or directory

Am I doing something wrong?

Operating system: Ubuntu 9.04
LLVM was obtained with: apt-get install llvm
