OK, I can understand that ... but what if you do not want -m32 support on your
system ... whatever.
Anyway, what I really don't completely understand is how to install additional
packages without screwing things up. OK, the rpm -ivh glibc-devel... did the
right thing and installed and I am now building gcc.
I just completed building glibc 2.3.2-101.4 for the x86_64 and have downloaded
the i386/i686 packages also. I plan to put these into a single (local)
repository and then do an upgrade on the x86_64 system using up2date.
Hopefully up2date will know how to do things "right".
But what if I wanted to do this "manually" with just rpm? How do I do this
"safely" so that I do not wind up with a system with 64 bit applications and
32 bit libraries. Right now my x86_64 system is pure testing so if I screw
it up it is not a big deal. But this will be an issue later. Whether it has
been big iron mainframes or small microcomputer, I am more familiar (more
comfortable) with single architecture systems. Yes, the IA32 systems have
i686 and athlon packages but they are few and easily understood. If I do not
do things "right", I could replace stuff in /usr/bin, etc/ with 32 bit
versions.
Before I started porting nessus to the 64 bit environment, I tried to install
the 32 bit version. I soon found that the requires 32 bit libraries and it
was like pulling on a bowl of spaghetti with more and more 32 bit libraries
required. It became easier to do the port (which has been successfully BTW).
Fedora Core is fairly lean and mean with respect to the 32 bit libraries it
installs (compared to the two dvd system that SUSE has). So how do we
install additional 32 bit libraries "safely"? And how do we then maintain it
when i386/i686/x86_64 packages are updated?
Any guidance will be appreciated.
