Hi guys, i've been developing with OpenCL for a while now and i did just fine on previous versions of ubuntu.
After updating to ubuntu 10.10, i can only run OpenCL on my CPU.
I have ati mobility radeon 4650.
I'm using ati catalyst driver 10-11 (built deb packages and installed them).
For OpenCL i tried both the .deb packages from a post here on the forum and ati stream sdk v2.1 tarball (I was able to compile the samples but they gave me CL_DEVICE_NOT_FOUND error at the end of every run).
any ideas?
run FindNumDevices from CAL examples.
gives me this
./FindNumDevices ./FindNumDevices: error while loading shared libraries: libaticalrt.so: cannot open shared object file: No such file or directory
just tried 10-9 driver, same problem.
then there is a problem with instaled driver.
i used to have this same problem with cal in 10.4 but OpenCL detected my GPU never the less.
so what can i do now? i tried 4 different drivers, 10-4,6,9,11.
versions 4 and 6 worked fine in ubuntu 10.4 but here they break with xorg.
also i noticed that the menus are missing the Catalyst control center that i had in ubuntu 10.4 and 9.10.
Updating my kernel headers fixed this problem. :S
Osaad,
I saw in installation notes that ubuntu 10.10 is not listed in supported OSes.
Can you please describe the procedure which made it work for you?

i'm using the 10-11 driver from ati's website. and using the OpenCL packages from this post
then i just updated normally, it installed the new kernel headers 2.35.23.25 and the driver worked fine, OpenCL and everything was fine.
