cannot install ati sdk

cannot find -laticalrt

Hello

I've downloaded ati-stream-sdk-v2.0-lnx32.tgz and when I try to compile I get the following error:

$> make

.....

g++ -o build/debug/x86/cal_idct build/debug/x86//cal_idct.o build/debug/x86//Timer.o build/debug/x86//Samples.o -m32 -lpthread -ldl -L/usr/X11R6/lib   -laticalrt  -laticalcl    -L../../../../lib/x86 
/usr/bin/ld: cannot find -laticalrt

 

I've search the system for aticalrt.* but didn't find anything. Any suggestions ?

 

cheers

Luca

ps I have Fedora 12 (32bit system)

aticalrt*.so are part of fglrx or catalyst. you need them if you want compile CAL samples or run OpenCL samples on GPU.

try dive into opencl subdirectory and make only opencl samples. it should work.

cannot install ati sdk

thnx. I can compile the stuff inside ~/ati-stream-sdk-v2.0-lnx32/samples/opencl

I've added the ~/ati-stream-sdk-v2.0-lnx32/lib/x86 to LD_LIBRARY_PATH

 

However when I try to run, for example, CLInfo I get

ERROR: cl::Platform::get() (1)

 

or

 

$> ./NBody
Error: clGetPlatformIDs failed. Error code : unknown error code

Any suggestion what might be the problem ?

You must register the OpenCL ICD; otherwise, samples and other applications will fail to execute if this is not done. To register the ICD:

a. If one does not exist, create a folder /usr/lib/OpenCL/vendors.

b. Create the /usr/lib/OpenCL/vendors folder, if does not already exist.

c. Symlink [INSTALLDIR]/x86/libatiocl32.so into the vendors folder:

sudo ln -sf [INSTALLDIR]/x86/libatiocl32.so /usr/lib/OpenCL/vendors/libatiocl32.so

d. For 64-bit installations, you also must symlink [INSTALLDIR]/x86_64/libatiocl64.so to the vendors folder:

sudo ln -sf [INSTALLDIR]/x86_64/libatiocl64.so /usr/lib/OpenCL/vendors/libatiocl64.so

Samples and other applications will fail to execute if this is not done.

 

 

Please read installer note for more information.

I think I already did that (in a different way):

$> ldd CLInfo

    linux-gate.so.1 =>  (0x00c85000)
    libpthread.so.0 => /lib/libpthread.so.0 (0x00a30000)
    libdl.so.2 => /lib/libdl.so.2 (0x00a29000)
    libOpenCL.so => /home/luca/ati-stream-sdk-v2.0-lnx32/lib/x86/libOpenCL.so (0x00147000)
    libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x0014d000)
    libm.so.6 => /lib/libm.so.6 (0x00a4c000)
    libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00612000)
    libc.so.6 => /lib/libc.so.6 (0x008b2000)
    /lib/ld-linux.so.2 (0x00890000)
    librt.so.1 => /lib/librt.so.1 (0x00a8d000)

and inside /home/luca/ati-stram-sdk-v2.0-lnx32/lib/x86 is also libatiocl32.so (I have that path set in LD_LIBRARY_PATH)

Is that what you mean ? If not, could you give me a link to the install documentation?

no you must create that symlink because libOpenCL.so search for driver in that location.
