GCC, the GNU linker and the -z extract option

[eoin]

Hi,
     I'm a new poster here. I am porting some Solaris code over to Linux and using the GNU compiler and linker. Now I have a "meta library"(creating a "master" shared object from mayny shared objects) which creates fine in Solaris but in Linux it doesn't create as a meta library - ldd suggests that it depends on the libraries which were previously used to produce the meta library on solaris.
     Looking into this I can see that with every .so we effectively lose the identity and so with a metalibrary what we need to do is to "unravel" the .sos to produce the meta library.
     I do this in Solaris using the -z extract option. I can't see how to do this in Linux using the GNU linker. Anyone any ideas?

Thanks

This has nothing to do with gcc. Please ask it on binutils mailing list with
an example.
