Re: Help. Porting "FreeOCL" fails (atomic_ops.h missing, CLANG++ libc++ issues ...)

Hello Dimitry,

thanks for your response and patches.

I fixed that, I forgot the pkg-plist, also. Will followup the PR I sent.
it is a simple line:

BUILD_DEPENDS=	...

Is this going to be fixed with your patch in the ports tree?

I'm amazed by the speed you came up with the patches ...;-)

My port request can be found here:

http://www.freebsd.org/cgi/query-pr.cgi?pr=171376

and one for providing the OpenCL header:

http://www.freebsd.org/cgi/query-pr.cgi?pr=171375

Matthieu Volat also stated that there is another promising OpenCL port
"Portable OpenCL", pocl. It seems to have a better LLVM support by design:

http://sourceforge.net/apps/mediawiki/pocl/index.php?title=Main_Page

Attached you'll find my first naiv attempt to build a port-Makefile, but
I fail to fetch(1), since there is an authentication error while trying
to fetch from a HTTPS:// source.

My abilities in depp-insight-development are limited, so I'm happy if
some experienced developers could also look at those software projects
and help making a port ;-)

it would be nice having FreeOCL and portable OCL for comparison purposes
available on FreeBSD. I still have the hope to "lurd" more developers
and scientists back to FreeBSD. Never mind ...
