I installed CodeXL on ubuntu 11.10 , intel i7 cpu,
Followed these steps
AMD Catalyst Driver, release 12.6 installed
$ sudo apt-get install alien
$ sudo alien -k CodeXL*.rpm
$ sudo dpkg -i CodeXL*.deb
On every run it is giving this error
line 41: 2390 Segmentation fault (core dumped) /opt/AMD/CodeXL/bin/./CodeXL-
bin
if you look at requirement page you can see that it require ubuntu 12.04. but more importantly latest driver. IIRC minimal vrsion is catalyst 12.10 or 12.11. install latest driver and try again.
