problems getting gcc 4.6.1 going

[VibrantCascade]

Hi there, I'm running Redhat Enterprise 6. It's a fresh install with the default gcc installed, which is 4.4.5.

The problem is that I need gfortran 4.6 or later for the quad precision libraries and I've spent hours trying to both manually install a new copy of gcc by both downloading the 80 meg zip file and doing the 3 standard commands:
./configure
make
make install

Which always fails out on make. And I've also tried numerous RPMs off of the rpm sites to try to install either all of gcc or just gfortran. But those always fail as well with dependency problems, and when I try to install the dependencies they have more dependencies and sometimes the versions of the dependencies aren't compatible with each other it seems.

So, does anyone know a good RPM I could use to fully update gcc to 4.6.1? Or do you have some other advice on how to do this?

Thanks!

Sorry, this should be in the "application" forums I suppose. Feel free to move it.

Under fedora15 (and I suppose also under RedHat 6) there is a package gcc-gfortran.
If you install it with yum, it should resolve all your dependency problems (gcc, cpp, libgcc, ...).

$> yum install gcc-gfortran

and just run

$> gfortran --help

or

$> man gfortran

Yep tried that.

Package gcc-gfortran-4.4.5-6.el6.x86_64 already installed and latest version

The problem is redhat only has 4.4.5-6. I need at least 4.6.0 for the quad-precision math. So I was trying to install it myself.

Sorry, misunderstood!
Could it be that 'Fedora 15' users have more recent packages than 'RedHat Enterprise 6'. If you install fedora15, you have latest version :

$> yum info gcc-gfortran
Loaded plugins: presto, refresh-packagekit

If you try to install the Fedora15 package, you will certainly have the same problems as with make.
Suggestion: ask your question on Redhat forum.
