I am having trouble getting opencl up and running.  I am trying to install it on my ubuntu 10.4 box with an ati mobility hd4570 card. 

So far i have tried to follow the steps in http://developer.amd.com/gpu/ATIStreamSDK/assets/ATI_Stream_SDK_Installation_Notes.pdf

also found from this forum i believe that you need to register the icd from this post: http://forums.amd.com/forum/messageview.cfm?catid=390&threadid=129154

i do that, go to the samples folder and hit make, then go to the bin and try hellocl and get the error in the above post.

Anyone have any idea what else i need to be doing to get it working?

Of note, when i run findnumdevices i get a 1, presumably the cpu, so i also dont know if i have the right driver installed

Chocrates,

ICD registration is different for SDK 2.01 and SDK 2.1. Did you do it the correct way?

[Chocrates]

I'm not sure if i did the correct icd version, i think its in /usr/lib/OpenCL/vendor/

but ill check when i get back to my laptop.

I also tried your ubuntu package to no avail.

no now it is file in /etc/OpenCL/vendors

hm it can not download? strange. try it download again.

alright, it turns out that your package worked as intended, i just had $LD_LIBRARY set to something wierd, changed it to /etc/OpenCL/vendors and HelloCL compiles and runs.  Findnumdevices still gives me 1, but i really have no idea what its supposed to do so i will start writing some code and see if i have it working how i want it.

Thanks!

FindNumDevices returns the number of GPU's present. It is working as expected.
