Tips on debugging

[WEREMSOFT]

I'm trying to use a 3d library called small3dlib https://codeberg.org/drummyfish/small3dlib but can not make it work.

The library does not have dependencies. It's a single header library that requires the user to implement the "putPixel" function.

I used graphics.app demo as a starting point, but if I #include the library, the application stops working.

Any tips for debuging this king of problem? Where should I start looking when the application just don't run? Is there a troubleshooting checklist I can use?

Thanks.

There is a doc here but it likely needs to be updated.
