It seems that, for an unknown reason while testing my app, all predicates are redefined or removed. Indeed when problem occurs, my predicates raises unknown errors. And all subsequent calls do the same. If I look at exe file, it is untouched (same date than install time). Exe is build with swipl-ld with prolog and C files. It runs fine... until the problem occurs. > > --- Jan > > On 10/11/2013 10:48 AM, Olivier Sallou wrote: >> Hi, >> I have generated a swi-pl executable from my C and prolog files. >> >> Everything was working fine. >> >> I executed a script that went wrong (don't know what, but well... this >> is my problem to fix).
