Welcome to LQ.

The package Manager can be used too : Enter fftw and mpich into the "Search"


The terminal is easy to use : 1) su (+enter password)
2) yum install fftw-devel mpich2-devel

( All packages can be watched with 'yum search fftw mpich' ).

Adding en_US to language list
Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora. Please verify its path and try again

Please do this command : cat /etc/redhat-release

.. to decide the Fedora version.

you NEED TO fix yum first
that is a MUST !!!

now what version of fedora is this ?
only fedora 13 & 14 are currently supported .


from your error one or more of a few things might be happening
yum needs the version of "python" in the fedora repo
If YOU installed a different version that WILL kill fedora

or

you did a "upgrade " maybe even skipping a few versions ?
that will break things

or
this is a VERY old version of fedora
fedora 8 and older ???

so before you can install fftw 3 we need to know a few things

what version of fedora is this ?
and was / is it a clean NEW install or a " upgrade"

If that is all you see, then you have to set up your DNS information correctly before it will work.

Try:

ping www.google.com
to verify this.

well fedora might not be a good choice for you then .
Almost ALL programs are installed using the terminal , and most things in fedora are debugged or fixed in the terminal


ok i am assuming that firefox is working and it is just yum that is not
and this is a new fresh install of 14
what was the last things you installed ??
if an update then maybe an error occurred , it happens .
look in /var/log/yum.log

or did you install a different version of python using some rpm from the net ?
-- or --
and this might be it also
are you behind a wireless router and did not set up yum to use that
see the fedora documentation
