Debugging MegaTunix Tips
Posted: Thu Sep 23, 2010 11:25 am
For those fine strong adventurous souls, here's a simple set of steps to help debug megatunix issues.
NOTE:This applies only to the Unix Class of platforms (Linux, *BSD, OS-X), not Windows, as the Windows edition is actually cross-compiled under linux, even the self installer for windows is under linux.
Compile the sourcecode debugging enabled:
"cd" into the top level MegaTunix directory.
for regular tarball people:
or Git people:
To get a backtrace that is (hopefully) usable, do the following.
Make sure you have gdb installed (apt-get install gdb, yum install gdb, port install gdb, etc)
You should get a prompt something similar to the following:
type "run" at the prompt, and it'll start
Do what you can to make it crash, type "backtrace" at the gdb prompt then send the output to me, or open a thread on the Megatunix subforum for it.
If you run megatunix and get gtk+ warnings, those indicate a bug that could eventually cause a crash, though it'll most certainly make something not work right in the Gui.
in the gdb prompt use "run --g-fatal-warnings" and when it stops, type "backtrace" and send me the result or open a thread detailing WHAT IT TOOK TO GET IT TO CRASH, what version of MegaTunix it was, and so on.
