Hi Johannes,
I can't tell you immediately what's going wrong, but the first thing I'd
do is try running ldd on your .so to see which libs it's looking for,
and whether it's finding them all correctly. The process is slightly
complicated by Nuke adding its own rpath information, so I'm not sure
whether your plug-in's symbol resolution will check that first, but it
might give you a pointer.
You can also try using the LD_DEBUG environment variable (e.g. try
"export LD_DEBUG=help" and then run any command like "ls") to see which
libraries are being loaded from where at all times.
Hope that helps get you started.
Cheers,
- Chris

Hey dudes!
I have a silly question. I have a plugin that links against nuke and an
other lib ( houdini ). I compiled with Cmake and its default settings
regarding the rpath. If i use chrpath on the .so i see that the rpath is
set properly to the nuke and the houdini libs. If i use nuke.load() on
it i get an undefined symbol. I dont get this, i need to put houdini in
the LD_LIBRARY_PATH for it to work.
AFAIK the order is rpath, LD_...,runpath for dynamically linked libs. Is
there a reason why my .so with the right rpath still needs an LD_... path?
Maybe is an obvious C++ thing that i dont get :) Please help!
Thanks
Jo
