sudo apt-get install mythtv-dbg
Modify /etc/default/apport to set "enabled" to 1
Start the apport service. "sudo start apport"
Ran this in terminal and created gdbcommands in my home directory:
cat << "EOF" | tee ${HOME}/gdbcommands handle SIGPIPE nostop noprint handle
SIG33 nostop noprint set logging on set pagination off set breakpoint
pending on break qFatal set args -l myth.log -v important,general run
thread apply all bt full set logging off EOF
Then I ran this command in terminal:
william at CI5:~$ gdb mythfrontend -x gdbcommands
