This might be an option for us...  Then I'll need to look up the list of
modules which really get linked into other things, and see if it still
works on other platforms.

So the semantic of that option would be to create all .so files with a
lib-prefix.  This helps those dynamic loaders.  But it should also help
linkers.  That might not have been the intention, but if it hasn't other
issues, it makes no difference if it was intented or not.

Hmm, what exactly is your problem with need_lib_prefix?  It sounds, as if
your current problem (without that), is, that libtool is feeding a -lbla
argument to ld, if you try to link in bla.la, but ld is refusing to find
it (which is correct).  Now, if need_lib_prefix forces the .so file to
have a lib prefix, and has no other effects (which you failed to show, at
least I can't find them), making ld find libbla.so, although the .la still
is called bla.la, what is it precisely, that you don't like about it?

Hmm, it already seems implemented, or I'm missing something crucial in
your posts.


Ciao,
