Hi all. We are migrating from: - SCO Unix OS5.02 - SCO cc compiler 5.02 - INFORMIX-4GL Version 6.04.UC1 to: - Solaris 2.6 - gcc compiler 2.8.1 - INFORMIX-4GL Version 7.20.UD7. The following simple C program did work on the old server, and dumps a core on the new one: # cat TEST.c main() { int fgl_svstk, fgl_nret; /* start log file */ fgl_svstk = mark_stack(); pushquote("/tmp/informix.log", 17); fgl_nret = startlog(1); rest_stack(fgl_svstk); /* test log file */ fgl_svstk = mark_stack(); pushquote("test", 4); fgl_nret = errorlog(1); rest_stack(fgl_svstk); } The program is compiled with c4gl: - Version 6.04.UC1: # c4gl TEST.c -o TEST cc -I/usr/informix/incl/tools -I/usr/informix/incl/esql TEST.o -o TEST -L/usr/informix/lib/tools -l4gl -lnforms -lfesql -los -lasf /usr/informix/lib/tools/netlib.a -los -lasf -lgen -lnsl_s -lprot -lsocket -l x -lcurses -lm -lcrypt_i -lm -lcurses - Version 7.20.UD7: # c4gl TEST.c -fwritables-strings -o TEST /usr/local/bin/gcc -DASIAN -I/usr/informix/incl/tools -I/usr/informix/incl/e sql -fwritable-strings TEST.o -o TEST -L/usr/informix/lib/tools -l4gl -lnforms -lfesql -los -lasf /usr/informix/lib/tools/libasf.a -los -lasf -lgen -lnsl -lsocket -laio -lm - ltermlib /usr/informix/lib/tools/libgls.a /usr/informix/lib/tools/libglx.a gdb indicates that the program stops when executing the 'fgl_nret=startlog(1);' statement. Please should you have suggestions to fix that ? Thanks in advance for any help. Philippe

ummm....I am not certain if I should be asking this...but are the permissions on "/tmp/informix.log" right ? It should be writable cheers In article <81bjlq$deh$1@wanadoo.fr>, "Ph.

By default gcc places these in a read-only segment. This may be your problem. Art S. Kagel Sent via Deja.com http://www.deja.com/ Before you buy.
