</I>I know, that's why it's strange to me why when the package is built on the
BS the links end up on /usr/lib64 on the i586 package.

</I>><i>
</I>Well, that was just a suggestion from someone on this thread and it looked
to me like the right place too. On this particular case what I'm doing here
is not installing some files but creating some symlinks that the other
warsow package needs.

</I>><i>
</I>
The "warsow-data" package contains the data files of the game which are
arch independent. The "warsow" package contains all the binaries and libs,
but to be able to run the game, the binary expects to find the data files
on the same directory where the libs are, if not then the angelscript
module will fail loading. So, what I'm trying to accomplish is that when
warsow-data is installed, symlinks of the files in the data directory
(/usr/share/warsow/basewsw/*) are created on
/usr/lib{64}/games/warsow/basewsw/. It works on x86_64 but on i586 is
creating the links on lib64 instead of lib and I don't get why, you saw the
code in the spec, I'm not hardcoding any path on it:
%define gamelibdir %{_libdir}/games/warsow
%post
#Add symbolic links of the contents of basewsw to the directory were the
#package warsow install the libs, if not then angelscript fails to load.
for i in %{_datadir}/warsow/basewsw/*;
do
file=`basename $i`
ln -sf $i %{gamelibdir}/basewsw/$file
done
%postun
rm -rf %{gamelibdir}/basewsw

</I>><i> If you want to use /usr/lib all the time then do so (if that's what the
</I>><i> game binary expects) via %{_prefix}/lib not via %_libdir.
</I>><i>
</I>
That's not the case, as explained before, the symlinks have to be created
at /usr/lib for i586 and at /usr/lib64 for x86_64, but on i586 for some
reason isn't doing it.

</I>
I'll check this too.
