net-p2p/ethminer requires >=app-eselect/eselect-opencl-1.1.0-r4 #8

Open EoD opened 6 years ago

EoD commented 6 years ago

If you are using dev-libs/ocl-icd as the primary OpenCL provider, you need >app-eselect/eselect-opencl-1.1.0-r1 (and I tested it successfully with >=app-eselect/eselect-opencl-1.1.0-r4).

As the previous version of eselect-opencl only provide OpenCL 1.1 headers and hence compilation fails with a lot of weird errors.

This applies already to net-p2p/ethminer-0.12.0.

I have successfuly build with only CL_VERSION_1_2 - found (eselect opencl mesa).

EoD commented 6 years ago

If you are using eselect opencl mesa, then you are using the mesa headers and not the "global" headers (as they are called in app-eselect/eselect-opencl-1.1.0-r1).

If you are using eselect opencl ocl-icd, build failures will occur.

But it is possible to build with eselect-opencl-1.1.0-r1 and mesa eselected. Maybe should to do eselect management from ebuild and more warnings instead of adding >app-eselect/eselect-opencl-1.1.0-r1 to RDEPEND.

Also builds with eselect opencl beignet and eselect-opencl-1.1.0-r1:

-- Looking for CL_VERSION_2_0 - found
EoD commented 6 years ago

Yeah, as I mentioned above the problematic "global" headers are those provided by the old version of eselect-opencl and those are only used if you select ocl-icd. All other cases probably do work as eselect-opencl will then symlink the system headers to the vendor-specific headers (see ls -al /usr/include/CL/).
