Problem installing GFortran on RHEL6.5 with x86

Hello

I am having problems with installing gfortran.

It seems as though my problems are very similar to this old post here (http://www.linuxquestions.org/questi...th-x86-857141/).

I followed the advise in that thread and used "yum install libgfortran" which successfully worked. The problem is that this does not seem to have actually activated gfortran for me. When I use "man gfortran" I get back "No manual entry for gfortran". As expected trying to use gfortran returns a similar "bash: gfortran: command not found".

I have set up gfortran on other systems before but have never had this sort of difficulty.

Thanks for any help.

and you will

you install the compiler and not just a lib

Code:

su -
yum search gcc

there will be two FORTRAN compilers
the current gcc-gfortran ( gcc 4.4.7) and the old g77 in the "compat-gcc-34-g77"

ALSO
you will NEED!!! to have installed the gcc development tools and such

so
you will have to have ALREADY installed

Code:

su -
yum groupinstall "Development Tools"
-------------- or this hack that happens to actually work ------------
yum install gcc-c++

that last one by shear CHANCE!!!! should pull all the development tools

Thank you! That is the correct procedure for me. Everything works as expected now.
