Failed to load aparapi native library

[GoogleCodeExporter]

What steps will reproduce the problem?
1.while trying to run samle code squares 
2.
3.

What is the expected output? What do you see instead?
it is runing in JTP modde instead GPU mode 

WARNING: Check your environment. Failed to load aparapi native library 
aparapi_x86 or possibly failed to locate opencl native library 
(opencl.dll/opencl.so). Ensure that both are in your PATH (windows) or in 
LD_LIBRARY_PATH (linux).
Execution mode=JTP

What version of the product are you using? On what operating system?
i m using centos 5 and AMD card with AMD-APP-SDK-v2.5-RC2-lnx64 driver

Please provide any additional information below.
i already set LD_LIBRARY_PATH

Lets see if we can help. 

Are you sure you have catalyst driver and AMD APP SDK installed? 

Check /opt/AMDAPP/bin/x86_64 there should be a program called clinfo does it 
run OK?

Does it report your GPU device? (feel free to send me the output if you would 
like me to check for you). 

When you first log in does your LD_LIBRARY_PATH var refer to 
/opt/AMDAPP/lib/x86_64 ? It should (so that opencl .so's can be located)?

Did you extend LD_LIBRARY_PATH or replace it?

I note that you added two issues for this (#25 and this #26). I will delete #25 
and we can track it here.

AMD-APP-SDK-v2.5-RC2-lnx64 is installed 
yes clinfo is working correctly
LD_LIBRARY_PATH  is correctly refer

OK so yes looks like Catalyst and APP SDK is installed. 

I am not familiar with CentOS (RHEL derivative I think) but I would expect that 
/opt/AMDAPP should be the location of these files.  Maybe the install process 
for CentOS is different. We'll leave that for the moment. 

Is this a binary distribution (from 
http://code.google.com/p/aparapi/downloads/list)? or did you go through the 
build process and build from source?

Also did you encounter this error running any of the samples (mandel?) ?

I assume that you are running from the machine and are *not* remoting in (ssh, 
rsh) and that X is up (you are using an X Windows session rather than running 
from a Console). 

The example scripts (mandel.sh) set the java.library.path to point to the 
directory containing aparapi.so. Can you confirm that the directory is correct 
and contains the aparapi.so file.

Consider setting -Dcom.amd.aparapi.logLevel=FINE to see if we can extract any 
more information at run time.

ya it is  binary distribution.
i am encounter this error to running samples (both mandel and squres).
DISPLAY is perfactly export from server to client machine since mandel output 
in JTP mode coming in client machine.

Make sure that this is not a duplicate of 
http://code.google.com/p/aparapi/issues/detail?id=17

In short, "X-Forwarding" enabled on your remote session is incompatible with 
OpenCL.

the issue is not with "X-Forwarding" . i directly login to server but issue is 
same.
it is not able to load shared lib aparapi_x86 library. even it is in the path.
detail out put of mandel with -Dcom.amd.aparapi.logLevel=FINE is below.

So is a 64 bit Linux distro? 

Is the JVM also 64 bit?

Aparapi is trying to load aparapi_x86.so and should be trying to load 
aparapi_x86_64 if this machine is a 64 bit machine. 

Can you confirm bitness of the OS and the JVM?

You may need to install 64 bit JVM.

thnx frost.. 
after install 64 bit JVM it is working .

Excellent. Glad we got it working for you.
