[vlc-devel] Re: Compile VLC for debugging

[Andrew Stone]

Ok. How do you debug the code then? GDB is pretty useless with optimized code. Do you guys use tracing of some sort? I'd really like to be able to step through the code. Any help would be appreciated.

Thanks for the info,
Andrew

That's correct. The debug flag works as expected (it adds debug info,  
etc.), but -optimizations is a bit useless, as VLC's code is always  
being optimised with our current build system without having the  
possibility to change the level by hand. You can only specifically  
disable the usage of AltiVec optimisations (for PowerPC CPUs) and  
additionally, you may optimise for memory usage (--enable-optimize- 
memory).

We recommend you to use gdb for debugging VLC. Simply running VLC in  
it, is straight forward: "$ gdb ./vlc" (or similar; depending where  
your VLC binary is actually located). Using gdb is a bit more  
complicated, so please have a look at gdb's documentation.
