breakpoints being ignored(freebsd9)...HELP!!!

Just installed v3.5.5375 and trying to compile and debug a small 'hello world' application. Any breakpoints I set are being ignored. The code is below..
I have tried: Going into debug settings and having it load all breakpoints after main and also automatically stopping at main. Doesn't help.
My config is the following:
OS: FreeBSD-9.0-RELEASE-i386
Machine: MacBook Pro running paralell's
Gnome-2x
CodeLite was built from source from the ports tree.
Please advise.
Thanks,
Jeff
Code: Select all
#include <iostream>
int main(int argc, char **argv)
{
char c;
printf("hello world\n");
std::cout << "press any key to continue..." << std::endl;
c = getchar();
return 0;
}

Hi Eran...looks like there is an options that is being set ( 'f' ) that gdb is not recognizing...maybe version issue with gdb? or settings in codelite?

Hi Jeff,
GNU gdb 6.1.1 [FreeBSD]
Copyright 2004
Wow! There've been a few gdb releases since then...
DEBUG>>&"mi_cmd_break_insert: Unknown option ``f''\n"
-f is the gdb MI-interface way of saying: "if necessary, create a pending breakpoint". Presumably it wasn't available 8 years ago.
The good news is, you can turn off pending breakpoints in the Debugger Settings dialog. The bad news: though unchecking that option stops CodeLite doing 'set breakpoint pending on' during initialisation, the -f is hard-wired into the break-insert command. That's a bug that, though normally harmless, clearly isn't to you. I'll fix it.
Meanwhile, is it possible on FreeBSD to upgrade your gdb? (On Linux at least, it's not difficult to build your own.) If it is, that will be a slightly good idea for other reasons too. If not, you can fix your CodeLite by removing the '-f' from the several instances of 'break-insert -f' in Debugger/debuggergdb.cpp, then rebuilding.
Regards,
David

Fixed in trunk, r5439, so another alternative would be to build from svn.

Thank you David! - Everything is working now.
I upgraded to gdb7.4 and also seems to be working well!
