[Gambas-user] How to compile with debugging information enabled - compiles but then a coredump

[Richard Terry]

Benoit,

I've wiped a hard drive this morning, installed just kubuntu 12.04, put 
on only gambas and its dependencies, compiled successfully with the 
debugging information and installed valgrind.

Can you tell me how to run the webcam example within this to give you 
the information you need to debug the V4L problem?
