I was having a really huge problem trying to compile under Ubuntu hardy 64-bit. Until I found a complex solution. And then I found a more easy solution. See my thread here to know what I mean.
The problem was that in the first case I used
And the 'correct' way was
sudo sh ati-driver-installer-8-5-x86.x86_64.run --buildpkg Ubuntu/hardy
And my BIG question is: shouldn't the scripts for Ubuntu/Hardy and Ubuntu/8.04 do the same thing? Did someone forget to synch them, for the last two Catalyst releases?
sudo sh ati-driver-installer-8-5-x86.x86_64.run --buildpkg Ubuntu/8.04
