CentOS

Installation of CCP4 on CentOS

CentOS is a 100% compatible re-compilation of RedHat Enterprise Linux with all its security fixes, bugfixes and feature enhancements. Versions 2.1, 3, 4 and 5 exist and are maintained by a large group of volunteers.

32bit and 64bit versions exist for a number of platforms; most notably for Intel and compatible processors.

If you want to configure CCP4 using --with-x , you need "yum -y groupinstall 'X Software Development'"
There exists no blt RPM for RHEL/CentOS. So, simply "ln -s /usr/bin/wish /usr/local/bin/bltwish". This requires "yum -y install tk".
Following Tim Grüne's advice, comment out the modification of MANPATH in $CCP4/include/ccp4.setup

Tips and Tricks for a 64bit installation

create the file /etc/rpm/macros with the single line

%_query_all_fmt %%{name}-%%{version}-%%{release}.%%{arch}

This results in the type of package (i386 or x86_64) being listed for rpm and yum commands.
