5. my system has NO !! amd gpu installed

1) is this a 32/64 bit issue ???

2) why I have a global "/usr/lib64/libOpenCL.so.1" and a local "AMDAPPSDK-3.0/lib/x86_64/sdk/libOpenCL.so" file?

  → which I should use ?

3) LD_LIBRARY_PATH is NOT set…

important information !!

> rpm -qf /usr/lib64/libOpenCL.so.1
nvidia-computeG03-340.104-11.1.x86_64

the library "/usr/lib64/libOpenCL.so.1" is from nvidia…

→ so, now the next question… WHY does the AMD tool "clinfo" not using the AMD library "/home/XXX/AMDAPPSDK-3.0/lib/x86_64/sdk/libOpenCL.so" ???

library issue solved… but core still exist…

nasty "LD_PRELOAD" issue…

> LD_PRELOAD=/home/XXX/AMDAPPSDK-3.0/lib/x86_64/sdk/libOpenCL.so clinfo 

ERROR: ld.so: object '/home/XXX/AMDAPPSDK-3.0/lib/x86_64/sdk/libOpenCL.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored.

fails because "libOpenCL.so" is a symlink and NOT the real library "libOpenCL.so.1"
