Maybe it's related to gcc-5.3. But I don't have any clue, why it fails. Didn't discover an usable error message.

Interesting.

[Comment 3 Sven Müller 2016-03-14 19:13:35 UTC]

Thanks for this hint. Found in nvidia-cuda-toolkit-6.5.14.ebuild:

src_prepare() {
        local cuda_supported_gcc

        cuda_supported_gcc="4.7 4.8"

        sed \
                -e "s:CUDA_SUPPORTED_GCC:${cuda_supported_gcc}:g" \
                "${FILESDIR}"/cuda-config.in > "${T}"/cuda-config || die
}

If use a Nvidia Quadro FX3800 graphics card. It's supported by the nvidia legacy driver 340.xx. That's also the constraint for the nvidia-cuda-toolkit version (limited to 6.5.x).

I just tried it without cuda support. Opencv compiles fine. 

How do we want to treat this problem now? The best thing would be, if nvidia supports >=gcc-4.9 for compiling the nvidia-cuda-toolkit. But I guess, they won't backport any patches to the legacy versions.

[Comment 4 Silvio 2016-03-21 21:25:34 UTC]

I confirm, as for r1 versions it is necessary to put:


=media-libs/opencv-3.1.0-r1 -cuda
=media-libs/opencv-3.1.0-r2 -cuda

in 

/etc/portage/package.use

and than it compiles..

[Comment 5 David Seifert 2016-03-25 17:10:18 UTC]

I suggest adding a pkg_pretend() check for this and failing on GCC 5 and above. Is this ok with all parties?

[Comment 6 Sven Müller 2016-05-07 18:38:32 UTC]

Daniel:
The check should be aware of the older CUDA versions. I would conjecture, >=nvidia-cuda-toolkit-7 may compile with gcc-5 and therefore, opencv should compile with >= gcc-4.9 too.

[Comment 7 Amy Liffey 2016-06-09 18:30:14 UTC]

Fixed in opencv-2.4.12-r1 and opencv-3.1.0-r4.
