Re: Prolog and C code works on PowerPC, fails on Intel

[Daniel Diaz]

You dont give us enough information (which version do you use ?). 
However I suspect you dont use a wrapper to invoke the main() function. 
Last versions of GNU-Prolog need this. You have to invoke Start_Prolog() 
in another function than main(). So your main() calls an auxiliary 
function which invokes Start_Prolog().

You can find an example at:
http://gnu-prolog.inria.fr/manual/manual070.html

Good luck !
