When trying to set a breakpoint on a compiled program for printf it just fails and doesn't stop. Kernel is : Linux frugalware 3.3-fw4 #1 SMP PREEMPT Mon Apr 23 02:41:52 CEST 2012 x86_64 GNU/Linux Glibc is : 2.15 ( tested with 2.14.1 and same result ) and gcc is 4.7. Here is what gdb says when it starts: GNU gdb (GDB) 7.4.1 ................. This GDB was configured as "x86_64-frugalware-linux". Program is this small test one: #include <stdio.h> using namespace std; int main() { printf("we have a printf\n"); return 0; } and it was compiled with : g++ -ggdb3 -o test main.cpp It works to set a breakpoint in for main but when trying to set one for printf I get: (gdb) break printf Function "printf" not defined. Make breakpoint pending on future shared library load? (y or [n]) y Breakpoint 1 (printf) pending. (gdb) run Starting program: /home/marius/proj/mariustry/test warning: Could not load shared library symbols for linux-vdso.so.1. Do you need "set solib-search-path" or "set sysroot"?
