1.5.2 Linux packages
To add the necessary modules to the Linux kernel, the setup program needs the following Linux
packages:
 The package with kernel headers or sources. The package version must match the kernel version.
 The GNU Compiler Collection (GCC) compiler system. The GCC version must be the one with
which the kernel was compiled.
 The Make tool.
 The Perl interpreter.
The names of these packages vary depending on your Linux distribution.
In Red Hat Enterprise Linux, CentOS, and Fedora, the packages normally will be installed by the setup
program. In other distributions, you need to install the packages if they are not installed or do not
have the required versions.
Are the required packages already installed?
To check whether the packages are already installed, perform these steps:
1. Run the following command to find out the kernel version and the required GCC version:
cat /proc/version
This command returns lines similar to the following: Linux version 2.6.35.6 and gcc
version 4.5.1
2. Run the following command to check whether the Make tool and the GCC compiler are installed:
make -v
gcc -v
For gcc, ensure that the version returned by the command is the same as in the gcc version in
step 1. For make, just ensure that the command runs.
3. Check whether the appropriate version of the packages for building kernel modules is installed:
 In Red Hat Enterprise Linux, CentOS, and Fedora, run the following command:
yum list installed | grep kernel-devel
 In Ubuntu, run the following commands:
dpkg --get-selections | grep linux-headers
dpkg --get-selections | grep linux-image
In either case, ensure that the package versions are the same as in Linux version in step 1.
4. Run the following command to check whether the Perl interpreter is installed:
perl --version
If you see the information about the Perl version, the interpreter is installed.
