Has anyone thought Yes, I discussed with Stefan about static lib dependency too, and don't have any conclusion about it. Here are the possible difficulties: For any missing symbol in one static lib, we can possibly find more than one matches in other static libs. Besides, searching through ALL static libs in one machine to find matches is very time consuming, and (unconfirmed) possibly give different results in different machines. This is not unsolvable, for example, by recording all missing symbols of static libs somewhere, and grep the lists of symbols instead. I have a conjecture: dependency of static libs must be a subset of dependency of dynamic libs. Will it be simpler if my guess is true?

Hi, it would be nice if the find_requires script would parse the dependancies of static libraries, but how to do this? It's easy to find out the dependant libs of shared libraries, but AFAIK shared libraries only contain information about which symbols are unresolved, but no information on where to get that symbols. Has anyone thought about using the libtool .la files to get the dependant libs? Or maybe it would be possible to use the dependany information from the shared libraries for static libs, that means if libfoo.so depends on libbar.so, does libfoo.a depends on libbar.a? -- What difference does it make to the dead, the orphans and the homeless, whether the mad destruction is wrought under the name of totalitarianism or the holy name of liberty or democracy?

[Cooker] find_requires script don't take to statically linked obj
[EMAIL PROTECTED] BUILD]$ urpmi vrb Some package requested cannot be installed: libvrb0-devel-0.4.0-1mdk.i586 (due to unsatisfied linked, due to unsatisfied statically) I just build this, i haven't take care, but this ugly script produce statically linked lib. I am fixing my package about this, but would be nice that find_requires take care to this. Somes apps can need static linkage, thinks to rescue apps. Thanks. -- Linux pour Mac !?
