First of all I would like to say hello to the AMD Developer community as this is my first post.

 

I always had interest in parallel processing hence after getting a Radeon card I wanted to experiment with AMD APP. I was a following the tutorial in http://www.thebigblob.com/getting-started-with-opencl-and-gpu-computing/ .

 

I have installed the latest AMD Catalyst Drivers as well as AMD APP 2.6 (32 bits) on a system with Radeon HD 5450. I don;t get any compilation error while compiling the host. However the program receives a SIGSEGV while executing. While debugging I noticed that clGetPlatformIDs was causing the problem.

 

Here is a screenshot of kdbg debugging the host:

Can't understand where it's breaking. I am running kernel 3.2.9 on ARCH and I have installed the latest version of catalyst-total from AUR.

 

 

Cheers,

 

Utsav
