Debugging Tutorials
These tutorials are aimed at people who know C and programming, but are just starting out with Wine development. They're meant to show you how to debug problems when apps don't work.
Firstly read the quickstart guide.
Debugging Reason 3 - a simple "Unhandled exception" error message. Introduces debug tracing, the shell DLLs and SEH/exception tracing.
Debugging the PE Explorer file open dialog - fixing a simple hang (yet another shell bug). Introduces backtracing using winedbg and different types of result codes.
Debugging 'Wild Metal Country' - finding why a game crashes (due to DirectPlay) and how to confirm the bug.
Source Code Management
Wine development is done with GIT, see this page on how to do wine development with GIT.
