incompatible intel opencl 2012 library

[blshkv]

I'm unable to build wisecracker with intel-ocl-sdk 2012 (2.0.31360).
(http://registrationcenter.intel.com/irc_nas/2563/intel_sdk_for_ocl_applications_2012_x64.tgz)

Here is the error message:

cd /var/tmp/portage/app-crypt/wisecracker-1.0/work/wisecracker-1.0_build/src && /usr/bin/cmake -E cmake_link_script CMakeFiles/wisecracker.dir/link.txt --verbose=1

Any idea what's the problem?

Hi
I had no problem building with the 2.0.31360 Intel OpenCL SDK on a
64-bit Debian 6.0 distribution. Here is how I did it.

Let's say you have installed the Intel OpenCL SDK in a directory called
/var/tmp/myintelsdk/

Here you have to note that this directory needs to have the include and
lib64 subdirectories accordingly. Hence the directories
/var/tmp/myintelsdk/include needs to exist.

$ export OPENCL_ROOT=/var/tmp/myintelsdk/
$ make rebuild

This should do it.

If you have /var/tmp/myintelsdk/usr/include present then your
OPENCL_ROOT will be
$ export OPENCL_ROOT=/var/tmp/myintelsdk/usr

If you have installed OpenCL in /usr/local then your OPENCL_ROOT will be
$ export OPENCL_ROOT=/usr/local

Hope this helps. Feel free to contact me if you continue to have issues.

Regards
Vikas.

ok, the problem was on my side with an ebuild (I compile under gentoo). I managed to fix it.
Thanks for the quick reply anyway

How can I tell to use the m64 option?..

You can use ARCH=x86_64 from the command line and that can force it.

$ make ARCH=x86_64
