[Libcdio-devel] cd-info linking conflict

[plaum]

Hi,

I want to install the current CVS to /opt/gmerlin, but I have an older
libcdio in /usr/local (installed it for vcdimager I guess).

I get the error:

Normally, each library should allow installation of different versions in
under different prefixes, shouldn't it?

After using ldd a bit, it appears, that linking cd-info with -lvcdinfo
is doomed to failure, because if this dependency relation:

        /-> libcdio.so (newly installed)
cd-info
        \-> libvcdinfo.so -> libcdio.so.X (already installed)

How can one solve this?

IMO the only possibility is to remove any reference to libvcdinfo
from libcdio and move the vcdinfo related functionality from cd-info
to a similar tool in the libvcdinfo package. But maybe someone proves
me wrong :)
