I'd recommend one of the 7.0.90.xxxx sources: ftp://sourceware.org/pub/gdb/snapshots/branch/ I've been using them to try and get Python working for MinGW. > If I can remember, the gdb.exe built from snapshot of 20100302, 20100301 > always get crashed on startup either. What do you see when gdb crashes? > I would prefer some gdb gurus can help. Thanks. I'm no guru by any means, but in order to create a profiling gdb one way is to specify CFLAGS at configuration time: $ CFLAGS="-pg" ../configure .... Once you have a gdb binary with profiling enabled, it should produce a profile file (a.out if memory serves), which you can then view using 'gprof a.out'. Cheers!
