I've got a problem installing XFree86 4.2. When I run the install script XInstall.sh the following message appears:

Welcome to the XFree86 4.2.0 installer

You are strongly advised to backup your existing XFree86 installation
before proceeding. This includes the /usr/X11R6 and /etc/X11
directories. The installation process will overwrite existing files
in those directories, and this may include some configuration files
that may have been customised.

If you are installing a version different from 4.2.0, you
may need an updated version of this installer script.

Do you wish to continue? (y/n) [y]
Checking which OS you're running...
uname reports 'Linux' version '2.2.19', architecture 'i686'.
Object format is 'ELF'. libc version is '6.1.3' (6.1).

Xinstall.sh: ./extract : Permission denied
extract doesn't work properly, renaming it to 'extract.bad'
ln : cannot create hard link 'extract' to 'extract.exe' : operation not permitted
chmod: extract : No such file or directory
Xinstall.sh : ./extract No such file or directory
extract.exe doesn't work properly, renaming it to
'extract.exe.bad'

The versions of 'extract' and 'extract.exe' you have do not run'
correctly. Make sure that you have downloaded the correct
binaries for your system. To find out which is correct,
run 'sh Xinstall.sh -check'.

When you have corrected the problem, please re-run 'sh Xinstall.sh'
to proceed with the installation.

-------------------------

Why can't I create a hardlink? I've already checked the required files and I'm using the correct ones!

Check the permissions on the file "extract". Make sure the execute permission is set.
Also, it looks like you're not running this as root... but this is just a guess.

I've also done the installation manually with the folowing commands:

chmod +x extract
rm -f gnu-tar
ln extract gnu-tar

After entering the ln command he says that he cannot create a hard link, but I'm logged in as root with the su command. Or do I have to login as root from the beginning?

I've already solved the problem. I was using the chmod command on files on fat32 filesystem and that doesn't work!
