ATI Stream SDK

Siassei
Hello,
I'm installing the ati stream sdk on ubuntu 10.10 with native gpu driver.
ati-stream-sdk + icd-regristration
from http://developer.amd.com/gpu/ATIStreamSDK/Pages/default.aspx

After running a first example I become an error as
Exception in thread "main" com.jogamp.opencl.CLException$CLPlatformNotFoundKhrException: can not enumerate platforms [error: CL_PLATFORM_NOT_FOUND_KHR]

What I make false.

Thanks,
  Thomas

Re: ATI Stream SDK

Examples from ATI in C running well.

Edit: I think, its an error that occurs from jocl. I have an build-server release for linux-86_64.

If I download the source code from mbiens or s... git repository. I can build gluegen and jogl. But with jocl I become a lot of build errors. :-(

Example: Error log with sgothel repository

hello Thomas,

should work. We are testing on the same setup (and also on NV).

a bit more information would be helpful.

what example are you running?

does the webstart CLInfo util work?
 -> http://jogamp.org/jocl-demos/www/

best regards,
michael

Re: ATI Stream SDK

Hello Michael,

> what example are you running?
The examples from the ati sdk (native files)

-----------------------------------------------
My first opencl call in my programm is
"CLPlatform.listCLPlatforms"

and this throws to (use the jocl linux_x86_64 build from the build server)
Exception in thread "main" com.jogamp.opencl.CLException$CLPlatformNotFoundKhrException: can not enumerate platforms [error: CL_PLATFORM_NOT_FOUND_KHR]

        at com.jogamp.opencl.CLPlatform.listCLPlatforms(CLPlatform.java:152)

---------------------------------------------------------------------
If I want to build jocl by the source code from http://jogamp.org/jocl/doc/HowToBuild.html
cd jogl
ant jar // o.k.
cd ../jocl
ant jar // -->
/home/siassei/Projects/Private/jogamp/jocl/nbproject/build-impl.xml:111: The J2SE Platform is not correctly set up.
 Your active platform is: default_platform, but the corresponding property "platforms.default_platform.home" is not found in the project's properties files.
 Either open the project in the IDE and setup the Platform with the same name or add it manually.
 For example like this:
     ant -Duser.properties.file=<path_to_property_file> jar (where you put the property "platforms.default_platform.home" in a .properties file)
  or ant -Dplatforms.default_platform.home=<path_to_JDK_home> jar (where no properties file is used)

It does'nt work. With openjdk and sunJDK doesn't work.

Re: ATI Stream SDK

Are you sure the opencl library is in the library path?

I also seem to recall at least one verison of jocl trying to open libOpenCL.so.1, but the ATI library is just called libOpenCL.so

I just created a softlink for the name issue,

 ln -s libOpenCL.so.1 libOpenCL.so

And setup LD_LIBRARY_PATH to point to the ATI sdk before running anything.

Re: ATI Stream SDK

Michael Bien
hello everyone,

regarding foo.so.1:

right, must have been a older jocl build. Currently jocl will only try to load 'libOpenCL.so' on linux (as specified). I am not sure if any of the SDKs still uses the .1 notation, but maybe this might be the issue here.

@Thomas it still fails if you call CLPlatform.listPlatforms()?

regarding the build error:
You will have to build gluegen + jogl first and make sure every project finds each other.
see build step 1:
Now you should have following directory structure: 
    /home/dude/projects/jogamp
    /home/dude/projects/jogamp/gluegen
    /home/dude/projects/jogamp/jogl
    /home/dude/projects/jogamp/jocl
-> http://jogamp.org/jocl/doc/HowToBuild.html


it would be also nice to check if the webstart CLInfo demo is working, since it uses an older build:
does the webstart CLInfo util work?
 -> http://jogamp.org/jocl-demos/www/


sorry for the delay,

michael
