It's hard to tell without more information. You might need to compile with
debugging and set a break point in lt_dlopen() to see what is happening. As
best as I can tell, libltdl thinks that the .so object is a libtool .la file,
and is trying to parse it as such. This might be due to the way it is
called, or a logical error inside the library. Part of the sequence for
lt_dlopen("libfoo") is indeed to try "libfoo.la", though it is not supposed
to be a fatal error, and should only be tried after opening "libfoo" (without
the suffix) has already failed.
If you are able to provide a minimal program that demonstrates the problem
you are experiencing, I would be happy to debug it from libltdl and down.
Cheers,
Gary.
