Hello all,
I am running CentOS 5.6 64 bit.
When running "yum -y install ncurses-devel", I expect that only ncurses 64 bit version will be installed.
Try: yum -y install ncurses-devel.x86_64
Or, add “exclude=*.i?86” in your /etc/yum.conf before running the same command you did earlier.
HTH,
RHEL/CentOS always installs both 32-bit and 64-bit libraries, that is the way Red Hat wanted it, so Applications designed only as 32-bit can run without any modification on 64-bit system. If you check other packages, you will see many have 32-bit counterparts.
This is normal behavior without any repercussions, so unless you intend to remove all 32-bit libraries from your system, I recommend to go ahead and install both 32-bit and 64-bit packages.
