You need to use -O0 -g3 to switch on debug from a gcc compiler. HTH -- Derek Ramazan Girgin wrote: > Hi all, > I am writing with eclipse in linux( Pardus ).

Error accessing memory address 0x3b24481778: Input/output error." It's not related with SELinux, as I disabled selinux (SELINUX=permissive in /etc/selinux/config) and the problem persist. If you need any more info, please tell me.

A reproducer would be the best one. Otherwise I need at least: (gdb) info breakpoints 1 and either (gdb) info proc mappings or (preferred) cat /proc/PID/maps where PID is the _debugged_ process, either from `ps axwf' or from (gdb) p getpid () Thanks. > It's not related with SELinux, as I disabled selinux (SELINUX=permissive in > /etc/selinux/config) and the problem persist. Have you rebooted afterwards? `setenforce 0' is both easier and IMO even safer method. You can verify the current status with `getenforce'.
