How would people feel about the addition of a new function
lt_dlhandle lt_dlopen_interface(const char *name, int interface_number);
which would return a handle to a library satisfying the given
interface_number or NULL if no such library is available in the search
path.
Without this, there's no way to (portably) make sure you get the
actual library you need. You just get first-available, which might be
the wrong one.
Further, the job this function is intended to handle is not one that
the calling code could easily implement, since only libtool is
supposed to know the architecture specific details regarding a given
library's filename, and since libtool should probably be solely
responsible for deciding which library versions satisfy which
interfaces.
So you would say:
lib = lt_dlopen_interface("libsomething" 4);
Trying to solve this problem outside libtool seems likely to involve
fairly awkward library filesystem placement, and LD_LIBRARY_PATH
tricks.
If people think this is a good idea, I'd be happy to help write the
code.
Thanks
