Well, I suppose nvidia is not only provider for opencl (ati/amd) is there really the need for hard dependency on nvidia on non-nvidia platform? is there a way to use opencl on AMD Llano in this case (ati drivers do have opencl use flag...) Reproducible: Always Steps to Reproduce: 1. USE +opencl on amd - only system with ati-drivers 2. emerge -avuD --newuse world Actual Results: dependency conflict ati/nvidia drivers Expected Results: no need cor nvidia drivers # emerge --info

the virtual is only half the problem. we have blockers atm between these packages. we'll need an eselect module to handle swapping out implementations, or perhaps integrating opencl with opengl. i've started an virtual/opencl ebuild so people will stop wasting random maintainers times (like imagemagick/wine): http://sources.gentoo.org/virtual/opencl/opencl-0.ebuild?rev=1.1
Note that amd implementation still requires headers for compile time deps AFAIK (eg. AMD-app-sdk https://bugs.gentoo.org/show_bug.cgi?id=257626 - maintainer wanted )
thanks for the heads up. i've dropped ati then for now. http://sources.gentoo.org/virtual/opencl/opencl-0.ebuild?r1=1.1&r2=1.2
The headers are standardized and can be pulled from (http://www.khronos.org/registry/cl/). It may be a good idea to package them separately rather than depend on the vendors to provide them. Maybe even mask the vendor's versions to resolve potential conflicts. Also, slightly related. The opencl use flag is (erroneously?) masked on the hardened profile. I'm attempting to setup an automated scientific computing system on a hardened server. I use both the CPU and GPU (AMD) opencl profiles for processing.

I've just made several commits that take that into account, see app-admin/eselect-opencl :) > Also, slightly related. The opencl use flag is (erroneously?) masked on the > hardened profile.

Yeah, that actually stopped me from committing updated version of virtual/opencl I've contacted hardened team so they could look into any issues.
*opencl-0-r1 (04 Feb 2012) 04 Feb 2012; Kacper Kowalik <xarthisius@gentoo.org> +opencl-0-r1.ebuild, metadata.xml: Utilize new app-admin/eselect-opencl and the fact that we now have 3 viable providers, use flags are no longer mutually exclusive
Thank you for your work... But now there is no dependency anymore to cuda-toolkit on nvidia systems. So a depclean removed it and now wine says when emerging: configure: error: OpenCL development files not found, OpenCL won't be supported. Perhaps nvidia-drivers should depend on cuda-toolkit when opencl USE flag is set? But ati-drivers doesn't have that USE flag too. I see this bug is set to resolved fixed. Should I file this as a new bug?

That's intended, x11-drivers/nvidia-drivers are enough to get working OpenCL. > So a depclean removed it and now wine says when emerging: > > configure: error: OpenCL development files not found, OpenCL won't be > supported. > > Perhaps nvidia-drivers should depend on cuda-toolkit when opencl USE flag is > set? > But ati-drivers doesn't have that USE flag too. > > I see this bug is set to resolved fixed. Should I file this as a new bug? I guess you've been hit by a bug 402407. Try running: eselect opencl set nvidia, latest version of ebuild already has it. Mea culpa...

I was using my own overlay nvidia-drivers-295.17.ebuild that was based on the 290.10 ebuild. So I didn't see the new one. Now I took the 290.10-r1 as my source and all is fine. Thanks
