Hi, I am working with kdevelop 3 that comes with FC2. When I want to debug and use the debugger inside kdevelop I have this error: (gdb) break serial.c:65 Breakpoint 1 at 0x8048685: file /home/rrodrigues/TRIVial/serial/src/serial.c, line 65. (gdb) run Error while mapping shared library sections: : Success. (gdb) backtrace Error while reading shared library symbols: : No such file or directory. Stopped due to shared library event #0 0x0054e480 in _dl_debug_state () from /lib/ld-linux.so.2 #1 0x00543961 in dl_main () from /lib/ld-linux.so.2 #2 0x00550e14 in _dl_sysdep_start () from /lib/ld-linux.so.2 #3 0x00542ac0 in _dl_start () from /lib/ld-linux.so.2 #4 0x005427c7 in _start () from /lib/ld-linux.so.2 (gdb) frame 0 #0 0x0054e480 in _dl_debug_state () from /lib/ld-linux.so.2 I went to the /lib directory and the ld-linux.so.2 is there (it is a symbolic link). But if I use KDbg there is no problem. I can debug. What can I do? I read some posts from other people but I did not find a solution. Can someone help me? Thanks, Rui Rodrigues
