my video card is HD4870, and system is ubuntu 9.10.

I try to opencl on ubuntu 9.10 for many times, but it fails.

After installing Catalyst 10.4, it fails to initialize.

I am not familiar with linux.

I want to give me some help to install opencl on ubuntu 9.10

Please be more specific about the issue you are facing.

What are the steps followed? What is the exact error message you are getting? Are you able to run the samples coming with the SDK?

Are you getting any error message during driver installation?

Did you have any drivers installed in your system previously?

Could you run the CAL sample 'FindNumDevices' and post the results?

[jacelyn5]

Today ,I reinstall ubuntu 9.10, the opencl samples can run. the resaon that samples cannot run is i install OS on Virtual Machine before reinstalling.

But?I trouble another problem.I need to install g++ complier,but give me some messages

" Mark additional required changes?

  The chosen action also affect other packages.

  The following changes are required in order to processed

  To be removed

            fglrx_amdcccle

            xorg_driver_fglrx

  To be installed

           g++-4.4

           libstdc++6-4.4-dev "

If click " done" to install g++, I don't make sure that opencl smaple could run.

How  can I do?

[llukas11]

type into terminal:

dmesg |grep fglrx

if driver is installed properly you should get something similar:

[    5.503720] fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, Starnberg, GERMANY' taints kernel.
[    5.532564] [fglrx] Maximum main memory to use for locked dma buffers: 1880 MBytes.

1. Install g++ and required additional dependencies.

2. Remove any older versions of display drivers

3. Install catalyst 10.4 drivers.
