No, as far as I know, libtool is for me to create my own libraries and link them with my program. I cannot use libtool to link others libraries, mainly if I do not know how they were created, right?

Yes, it's wierd I know! This binary is for a competition. It'll have to run on system without the libraries I use installed out of the box, except of course, gcc and glib which are standard in Linux systems.

Don't really know about that... :) Seems it just knows more than I do on these matters!
Ah, I guess rather than special-casing those two libraries, you would like to link all non-Glibc (and maybe non-GCC) libraries statically, right? (The rest of my mail assumes this somewhat.)
Right!
> So in general I should do: > -Wl,-Bstatic <LIBS> -Wl,-Bdynamic Hmm. I did a small survey about this a little while ago, as a first step to implement per-deplib static/shared switches in Libtool[1]. Above settings are fairly portable, but there are important exceptions.
Still, I don't understand how to use them with automake and autoconf! I don't think I can use libtool since these are not my libraries and furthermore, I do not have the slightest idea on how they were created.

Libtool-1.5.24 will have -static-libtool-libs, which will allow you this functionality portably, but only for libraries created with libtool. Eventually, the per-deplib flags feature[2] will appear in mainline libtool in some way or other, which will allow this for all kinds of libraries.
