X-BeenThere: freebsd-threads@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Threading on FreeBSD List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 21 Oct 2011 19:20:54 -0000 Hello all, I was wondering if gdb had support in FreeBSD to suspend one thread and run the rest. This is one flavor of an option called non-stop mode in gdb, and can be issued through the following commands: (gdb) set target-async 1 (gdb) set pagination off (gdb) set non-stop on (gdb) file foo Reading symbols from foo...done. (gdb) run -d The target does not support running in non-stop mode. In this case, the 'target' is FreeBSD. Does this mean that FreeBSD does not support this? Should I try using a different threading library? I am currently using the pthreads implementation in "lib_thr". Thanks! -- John Schumacher
