# Compiling/installing kernel modules
You will need to have installed:
1. The developmental packages (compiler)
2. The kernel source code that matches your running kernel
3. The module source or install code
Check out your system and look under the hood and see if you installed the stuff you need to do the job. Open an x terminal and type in this sequence of commands to see what kernel we are running and see if you have the kernel source installed:
Code:
[fancy@tinwhistle fancy]$ su -
Password:
[root@tinwhistle root]# uname -r
2.4.18-3
I am running kernel version 2.4.18-3. Do I have the proper source code?
Code:
[root@tinwhistle root]# cd /usr/src
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x 4 root root 136 Jun 12 14:53 .
drwxr-xr-x 16 root root 424 Jun 4 12:04 ..
lrwxrwxrwx 1 root root 14 Jun 4 12:11 linux-2.4 -> linux-2.4.18-3
drwxr-xr-x 16 root root 584 Jun 4 12:11 linux-2.4.18-3
drwxr-xr-x 7 root root 168 Jun 4 12:08 redhat
[root@tinwhistle src]#
I do have the same kernel version source code installed in the directory /usr/src/linux-2.4.18-3 and there is a symbolic link named linux-2.4 pointing to it.
If you don't see something similiar to this (but in color), you will need to install the kernel source.
NOTE: I noticed that Red Hat didn't make the symbolic link
/usr/src/linux that all of the INSTALL files that I have read mentioned that I need, so I may as well make one now to save editing the files in the source code to install.So, I'll make it just now:
Code:
[root@tinwhistle src]# ln -s linux-2.4.18-3 linux
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x 4 root root 160 Jun 12 15:46 .
drwxr-xr-x 16 root root 424 Jun 4 12:04 ..
lrwxrwxrwx 1 root root 14 Jun 12 15:46 linux -> linux-2.4.18-3
lrwxrwxrwx 1 root root 14 Jun 4 12:11 linux-2.4 -> linux-2.4.18-3
drwxr-xr-x 16 root root 584 Jun 4 12:11 linux-2.4.18-3
drwxr-xr-x 7 root root 168 Jun 4 12:08 redhat
[root@tinwhistle src]#
Ah, there it is, so that's done.
Next, did I install the compiler?
Code:
[root@tinwhistle src]# gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
[root@tinwhistle src]#
Yes, I have a compiler installed.
If you don't have those two things installed, you have to install them first off your install CD.
If they are installed, download the source and happy comiling.
Make sure you carefully read the README and INSTALL files after extracting and before compiling/installing.
