Well, to be specific, it is a gcc/gdb question. In order for gdb to trace
a function, it needs to have debugging symbols. And, there is a command
line switch "-g" in gcc which generates the debugging symbols, and there
is a program ("strip") that is commonly used to remove all these symbols
from a library before installing it.
But this question is relevant to the list because the answer is that you
need a "debugging build" of libav. You need to tell libav's makefile to
add "-g" to all calls to gcc, and tell the makefile not to run "strip" on
the library when you are done. Also, its handy not to get lost in
assembly code and you want your debugger to generally follow the source
line-by-line, so might as well disable optimizations while you're at it.
And, you do this with the configure command, which generates the makefiles
for you.
So your answer:
configure --enable-shared --disable-static --disable-optimizations
--disable-mmx --disable-stripping
You can look at ./configure --help for details.
Also, I had a post back on Nov 26 where I explained how to build a debug
version of libav and install it to a separate directory than the one that
is part of your system. Check the archives if that sounds like what you
need.
