.so interdependencies

Hello,

I would like to load a .so on Linux that I made myself (g++ -shared
*.o -o libmytest.so).

I can compile and run C programs against this .so, but when I try to
load it using ctypes:

test = cdll.LoadLibrary('libmytest.so')

I get an error:

libmytest.so: undefined symbol: slamch_

which is a function in a different library .so that is used by a
function in my library.

They are both in LD_LIBRARY_PATH. Is there a way to resolve this? I
have the freedom of creating the library, if that helps, but I don't
know much about shared libraries and how the dependencies between
libraries get resolved. Did I build my .so correctly given that it
works fine in other C programs that use it?

I have read one other post describing a similar problem but it didn't
seem to have gotten resolved.

Thanks,
Pål
