Prolog and C code works on PowerPC, fails on Intel

[Miguel Arroz]

Hi!

  I'm working on a project on Linux for PowerPC. I have a prolog file
linked with a (really big) project in C. It works perfectly on my PowerPC
machine.

  When I move it to an Intel machine, it fails on the first C call to
prolog. I do it like on the example on page 204 of the manual. First, I
call Start_Prolog, then Find_Atom (and it returns a positive int, not -1,
so it whould be working fine). Then, Pl_Query_Call. Here's the problem: it
returns an exception.

  First, how can I print that exception, to know what's happening? I
tried to read the PlTerm as String, but it fails and crashes.

  Second, why is this happening? When I test the example on that page on
the Intel machine, it works. It does not work on my project, but the C
code is mostly the same on the two machines...

  Yours

Miguel Arroz
