Perhaps the RPM dependencies are incorrect or irrelevant but when I
upgraded to Swarm1.2 on my Redhat5.0 box I upgraded gcc2.7.2.3 to
gcc2.8.1 because the Swarm binary build used it. Unfortunately I hit
the pow() bug and have had to use -fno-inline since. I looked into
egcs but the dependencies change re:

failed dependencies:
        binutils >= 2.8.1.0.15 is needed by egcs-1.0.3a-1

Redhat5.0 has binutils-2.8.1.0.1-1

There lies a quagmire that you enter at your peril since it's easier
to buy Redhat5.2! Anyway, I'll wait till I get a new machine (and
finish my thesis)!

However, during that period I had 3 gcc compilers installed and a
script that would link each one in as required. However, they were never
coexistent. When you suggest that's possible are you suggesting
renaming gcc to gcc2.7.2 and gcc2.8.1 etc. O.K. the gcc-lib libs will
be in subdirectories relevant to the release number but other things
(like the g++ include files for instance) aren't.

If you could advise me how it's possible to have gcc2.8.1 and gcc2.7.2
coexist I'd be appreciative. I have to use f2c since the g77 RPM will
not work with gcc2.8.1 and so I can't install octave. Hence I have to
drop into Windows to use MATLAB. Not that I have ANYTHING against
MATLAB of course ... it's contour graphs are the best in the
business. It's just the OS that gives me a sour taste!

Anyway, if there are any Redhat5.0 gcc2.8.1 (and probably 2.8.0) users
out there I installed Swarm1.4 O.K. The SantaFe R and NCSA HDF5
installed BUT only by setting compiler flags -fno-inline. This was
definitely the pow() bug at work. By the way, it might help to make a
note that HDF5 should be installed prior to R. The config script goes
by pretty quick ... I missed it.

Cheers.
