I should add that the minimal example is precisely the code that I wrote:

GEXTEND Pcoq.Gram
GLOBAL: myproof_instr;
  myproof_instr :
    [[ c=Pcoq.Constr.operconstr ; "." -> MyInstr.my_constr c ]];
END

With Ocaml installed in /usr/bin it fails complaining about myproof_instr not being defined, while in .opam's Ocaml it fails at the preprocessor level.

Thanks,

Beta

Hi list,

I have the following issue that is driving me nuts. I have two Ubuntu boxes with practically the same setup. I have a plugin for Coq 8.5 beta 2. However, I can compile it in one machine but not on the other. In the machine where it works, I have OCaml installed in the system (as in /usr/bin), while on the other is in .opam.  The error in the second machine is:

File "src/myfile.ml4", line 92, characters 13-14:
Parse error: [global] or [entry] expected after uppercase identifier (in
  [gextend_body])
File "src/myfile.ml4", line 1:
Error: Error while running external preprocessor

That line is:
GEXTEND Pcoq.Gram
GLOBAL: myproof_instr;
  myproof_instr :
    [[ c=Pcoq.Constr.operconstr ; "." -> MyInstr.my_constr c ]];
END

When compiling Coq, the ./configure -local script outputs the text below, where XXX is replaced by specific locations for OCaml: /usr/bin (or lib) for one machine, and .opam in the other.

Any ideas?

Thanks!

Beta
