Hallo!
How do you get gdb to find the sources for externals? It seems to find the Pd source fine, but not the source the objects I am working on.
hm ... you are right, break file:nr also doesn't work for me ... I just read somewhere that maybe you can set "break main" and then when the program stops set the breakpoints for the libraries ... but I don't know ...
What platform are you on? I am on Mac OS X.

Get ready to laugh... when I need to run gdb on an extern, I just link the thing into Pd, debug it, and then take it back out. Easier than figuring out how to get gdb to see dlopen()-ed code...

type this in gdb:
add-symbol-file my_blah.pd_linux
it's the second line when you type this other gdb command:

It worked, breakpoint and all. Now I need to learn gdb. Anyone know a good, quick gdb intro? Its been 10+ years since I used it.
Here's a little transcript:

it should be possible to run an embedded gdb in about every editor, that's designed for writing source code ... i've been running gdb within emacs and eclipse and i guess, other ide's like vi(m), kdevelop offer similar features (well, maybe not nano or pico) setting a breakpoint in emacs/gud is as simple as typing C-x space ....

I started a wiki page to start documenting this and filled in my session. More info would be greatly appreciated.
