There shouldn't be. What does gdb show you for other files? Maybe check if the 
.so are stripped. This will tell you:

   file /opt/darktable/lib/darktable/libdarktable.so

Apart from that there is no magic involved, it always just worked for me.

Ok. Is there then something I am missing or doing wrong since gdb cannot 
debug into other files than main.c? Is there a special trick?

It's not designed to be runnable without installation.
You may want to
$ sudo mkdir -p /opt/darktable
$ sudo chown youruser:yourgroup -R /opt/darktable

And now when you do  ./build.sh --install  it will end up in there.

(Of course, you can pick any other directory, but then you need to
pass it e.g. via --prefix to build.sh)

[darktable-dev] Debugging of darktable.

[Jørn Villesen Christensen]

Hi there,

I have been trying to debug darktable (with gdb) but without any luck.

My main problem of running darktable from the build directory is that it 
will not load any modules. I have tried to play with --datadir, 
--moduledir, and symlinks, but without any luck. I can get the UI up 'n' 
running - but no modules are loaded.


Alternatively I have tried to install darktable in a temporary directory 
next to the build dir, but that fails as well. It launches well, but 
then gdb fails to debug any other files than main.c and I suspect it is 
due to the changed file structure.


So... is it possible for any of you to sketch up how you debug darktable?
