The RPM packaging has been a bit of a problem for me as well, with
binaries or srpms.
First of all, libmysqlpp.so itself (the symlink) doesn't show up as a
file owned by the package, because it's only created and destroyed
during %post & %postun stages of the installation. This had two effects:
1) installing two different versions did not create a conflict; this
could be considered handy, if you had some reason to link to two
different versions of the library, but I think that's kind of far
fetched. More likely, it gave us some difficult-to-detect bugs, but I'm
not completely sure.
2) doing rpm -Uvh new.i386.rpm ... deleted the symbolic link without
recreating it. honestly, that seems like a bug, to me, in the upgrade
process to run %postun for the old version before doing %post for the
new one.
I don't yet completely understand the -soname option to gcc (is that
what it's from? I'll read up on it soon, I suppose), but what I did in a
locally modified .spec file is take out the ln and rm commands from
%post and %postun (respectively), and added
pushd $LIBDIR && ln -sf libmysqlpp.so.%{version} libmysqlpp.so && popd
to the %install area, and
/usr/lib/libmysqlpp.so
to the %files area.
Also, I've read that RPM automatically detects dependencies, but it did
not appear to do so, when I was using rpmbuild (RPM version 4.2.3).
What do you think is wrong with writing a patch for the Makefile (i
presume to add -soname to the gcc options)?
