glibc-debug: glibc-debug (GNU C libraries with debugging symbols) glibc-debug: glibc-debug: This package contains versions of the GNU C libraries with debugging glibc-debug: information. These are needed only if you wish to be able to step glibc-debug: through C library routines while debugging programs. Most debugging glibc-debug: efforts will not require these. glibc-debug: To use these libraries, set LD_LIBRARY_PATH when calling the debugger: glibc-debug: LD_LIBRARY_PATH=/usr/lib/debug gdb glibc-debug: glibc-debug: Or, use this approach if you need to debug a setuid binary: glibc-debug: su user -c "LD_LIBRARY_PATH=/usr/lib/debug gdb "
