Wrong!
:-)
Actually what you are doing *should* be unnecessary, because of the way
dynamic linking works, which I will endeavour to summarise:
Libraries have version information - major (the first digit), minor (the
rest).
The major versions can happily coexist. The minor versions should not -
they are simple incremental improvements, or bugs fixes, which do not change
the API. So there shouldn't be any reason to try to make them coexist.
For each major version there is a link
libxxx.<major> ---> libxxx.<major>.<minor>
For each library, there is a link
libxxx ---> libxxx.<newest-major>
Now, when you build a program, you don't normally specify the version. This
causes the latest versions to linked in. You shouldn't have to mess with
the symlinks - they should be maintained automatically for you (by ldconfig,
IIRC, on most machines).
So it is bizarre that this fixed your problem. I can only guess that maybe
you compiled the newest versions of the libraries *after* you compiled Imlib
and/or E. When compiling programs which depend on other shared libraries,
you must compile the newest versions first, and then run ldconfig.
Does that clear it up?
