Hi,

does anyone know how to make a static library, say libA.a, of a given shared library libA.so ? Is that possible at all? (needless to mention that I don't have the sources of libA.so)

Related to that question is how to merge two shared libraries libA.so and libB.so so that all references between libA and libB are internally resolved. That means later on, when linking something to libAB.so, no dependencies to libA.so nor to libB.so shall persist.

Obviously the naive approaches
and
do not solve the problem. I browsed the several man pages in the binutils package but could not find the answer there. Maybe objcopy could do the trick?

Hope someone can help me here.

Best,
vro

Static libraries aren't linked, whereas shared libraries are. You could make a shared library from a static one, but I don't believe you can go the other way. Since a static library is just an archive of object files, you would have to find a way to "unlink" the shared library. Additionally, some of the source files may have specified visibility attributes for functions or data which can prevent symbols from being exported, essentially making them unavailable.

I've tried incrementally linking an object file to a shared library to make a static library, but that hasn't worked for me. Do you have the source code for the shared library? You could tune the auto-tool files to force it to make a static library.

edit: Just noticed you don't have the sources. For your second question, have you tried using -rpath and -rpath-link?
