building rt73 module on fc6

[Alastair McKinley]

hi everyone,

I have a Belkin FD57050 USB wlan adapter which I believe requires the
rt73 driver found here:

http://rt2x00.serialmonkey.com/rt73-cvs-daily.tar.gz

So I downloaded the cvs nightly tarball, and tried to bulid it on a
fresh fc6 installation.

This is the error I got:

[root at localhost Module]# make
make: *** /lib/modules/2.6.18-1.2798.fc6/build: No such file or
directory.  Stop.
rt73.ko failed to build!
make: *** [module] Error 1
[root at localhost Module]#

[root at localhost Module]# rpm -qa | grep kernel
kernel-devel-2.6.18-1.2798.fc6
kernel-headers-2.6.18-1.2798.fc6
kernel-2.6.18-1.2798.fc6
[root at localhost Module]#

Any ideas why I cant build this?  Have i got some packages potentially missing?

Best regards,

Alastair
