It cannot compile a simple program (see config.log for the details). If you installed ghc from a generic binary tarball then it is worth checking that you have the 'gmp' C library and header files installed. (On Debian-based systems this package is called libgmp3-dev.) ==================================== I have made sure that libc and gmp are indeed installed. while trying use yum to make sure I have gmp installed. ==================================== [root@qa-engine1 haskell-platform-2012.2.0.0]# yum install gmp Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirror.stanford.edu * extras: centos.mirror.facebook.net * updates: mirror.stanford.edu Setting up Install Process Package gmp-4.3.1-7.el6_2.2.x86_64 already installed and latest version Nothing to do ======================================== Any help is appreciated.
