32bit and 64bit versions exist for a number of platforms; most notably for Intel and compatible processors. On PC-type hardware, one should probably choose the 64bit version if the machine has more than 2GB of memory and is used for computing. The 32bit version is better for web surfing: for example, there are more 32bit Firefox plugins than 64bit ones (but of course one could manually install the 32bit Firefox on a 64bit machine). | 32bit and 64bit versions exist for a number of platforms; most notably for Intel and compatible processors.

== using yum to identify which package a missing file belongs to == | |||
When "make" fails (e.g. during CCP4 installation from source), it is most likely a missing file. In this case the compiler complains, giving an error message which mentions the name of the file. If the name of the file is e.g. curses.h, ask you what package the file belongs to: | |||
yum whatprovides curses.h | |||
The output lists a number of packages which provide files whose names end with "curses.h". Pick the one ("ncurses-devel") that lists /usr/include/curses.h, and install it with | |||
yum -y ncurses-devel | |||
