Mr Kevin Turner, When I do just as you says : (gdb) attach 2029 Attaching to process 2029 0x40296121 in ?? () (gdb) l No symbol table is loaded. Use the "file" command. The source code is compiled as follow: gcc -DHAVE_CONFIG_H -I. -I. -I../.. -I/usr/X11R6/include -I/usr/lib/glib/include -I../.. -I/usr/local/include -g -g -O2 -Wall -c myread.c Thank you for reply.
