I have Fedora 20 and want to install the C compiler that support C99 standards.

Please suggest me site to download c compiler also help me installing it coz I dont know how to install the s/w in linux.

actully trying to install Metis (Graph partitioner) in fedora 20

Following are the instration given in Metis install file.

These are some preliminary instructions for the 5.0 release of METIS.

1. You need to have a C compiler that supports the C99 standard.
Gcc works just fine, but I have not tested it on many other architectures
(any feedback/patches for different architectures are welcomed)

2. You need to have GNU make and CMake 2.8 (http://www.cmake.org/) installed.


Please help

Resolving Dependencies
There are unfinished transactions remaining. You might consider running yum-complete-transaction, or "yum-complete-transaction --cleanup-only" and "yum history redo last", first to finish them. If those don't work you'll have to try removing/installing packages by hand (maybe package-cleanup can help).
