That's not what I asked... .h files do not get compiled, only .cc files are compiled. What is the name of a .cc file which fails to compile (any one of them is fine)? I.e. run the make and see where it dies. On my local system, it all compiles fine. If you give me the name of a failing file I can dig deeper.
EDIT: Actually looked at the README file. Looks like a statistical translator trained on example bitexts. Cool! I've done a bit of NLP programming myself.
