OCaml binding to SRILM ngram works!

I’ve emailed it back to Andreas. My own version of pplFile redirects cerr to ostringstream instead of cout, then captures it, later it’s parsed by three_fourths in The Perp System -- since ngram -debug 1 outputs teh perplexities of the sentences on the 3rd, and then each 4th line after that.

I’m creating LM clients inside C++ and return integer handles to OCaml; one’s supposed to call lm_destroy for every lm_create, and in reverse order, and no creations after deletions. This corresponds to my use case, but surely can be generalized for better bindings, and switched from static LMClient *clients[] to std::vector<LMClient*>.
