Re: libpng.so.3 Dependency Issues - Swarm installation

[Paul E Johnson]

Yes, there is an easy fix.

I only run RH7.2 now, but on my system, the libpng is updated compared 
to the standard distribution. In the same directory where I offer the 
hdf5 package, you can see the libpng too.

I bet that RH7.3 does not have the updated libpng. Ah, I see it does 
not. So in addition to the hdf5 rpm, you need these:

http://lark.cc.ukans.edu/~pauljohn/Swarm/miscSupportSoftware/libpng-1.2.0-1.i386.rpm
http://lark.cc.ukans.edu/~pauljohn/Swarm/miscSupportSoftware/libpng-devel-1.2.0-1.i386.rpm
(and this one supports legacy programs)
http://lark.cc.ukans.edu/~pauljohn/Swarm/miscSupportSoftware/libpng10-1.0.12-1.i386.rpm

If that does not get it, I'll check it out.

Could be I'll upgrade to a RH7.3 system over the weekend and then I will 
make you some new RPMS.  But you will still have the libpng problem.

In order to use the new Emacs, one must have the new libpng. Or at least 
it was necessary 3 months ago.

Building swarm from tarball is not a terrible thing anymore, but it is
still demanding and would require some care/study.  The best thing for 
you to do is to get the spec file I use to build the rpm and then use 
that to build a new RPM for yourself.  Much better than building the old 
fashioned way because it is easy to install/remove. Beware you need 
several devel packages that rh does not install by default.
