Fedora Linux Install Linux Kernel Headers And Developer Files

I'm trying to install vmware-tools but Fedora Linux v12 prompting for kernel headers. How do I install kernel headers under Fedora Linux?

You need to install the following two packages:

• kernel-devel : Development package for building kernel modules to match the kernel.
• kernel-headers : Header files for the Linux kernel for use by glibc.

Type the following command as root user to install required packages:
# yum -y install kernel-devel kernel-headers
Once installed type the following command to configure vmware-tools client package:
# vmware-config-tools.pl
