Bug 674570 – dev-util/nvidia-cuda-toolkit should support more versions of GCC

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Oleg Korsak 2019-01-05 02:36:40 UTC]

while it states here: http://eigen.tuxfamily.org/index.php?title=Main_Page#Compiler_support
that it supports GCC 4.8+, ebuild states that it supports 4.7 - 7.3 range only.

[Comment 1 Oleg Korsak 2019-01-05 02:38:32 UTC]

GCC 7.4 is out of "supported" range as well

[Comment 2 Arfrever Frehtes Taifersar Arahesis 2019-01-05 07:41:55 UTC]

List of supported versions of GCC is hardcoded in cuda-config tool from dev-util/nvidia-cuda-toolkit.

You can change cuda_supported_gcc variable in dev-util/nvidia-cuda-toolkit ebuild and reinstall it for testing...

nvidia-cuda-toolkit-10.1.105 supports for gcc-8.2 & 8.3

2.2.1. CUDA Compilers
The following compilers are supported as host compilers in nvcc:
GCC 8.x
Clang 7.0
Microsoft Visual Studio 2017 (RTW, and all updates)
Microsoft Visual Studio 2019 (Preview releases)
PGI 19.x
ICC 19.0
Xcode 10.1 (10B61)

[Comment 6 Alexey Korepanov 2020-06-24 22:15:21 UTC]

I can't build eigen with cuda use flag, because cuda does not support gcc-8.4.
I am on the latest cuda 10.2.89-r1.

It looks like the ebuilds for cuda allow gcc-8.4, but at the same time cuda_src_prepare() from cuda.eclass always fails with gcc-8.4, because it
takes allowed gcc versions from cuda-config -s, not from the ebuilds,
and the output does not contain 8.4.

https://bugs.gentoo.org/729156 depends on this bug.

> And the relation [of the error message] to cuda is far from obvious.

Whoever feels responsible for cuda.eclass, please improve the message so that ebuilds that are so kind as to provide optional cuda support do not receive bugs about it.

[Comment 9 Pacho Ramos 2020-06-27 10:08:11 UTC]

cuda looks to support it for me:
$ cuda-config -s
4.7 4.8 4.9 5.3 5.4 6.3 6.4 7.2 7.3 8.2 8.3 8.4

I think the problem is that ebuilds should have had a rev bump when committing
https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=1700a99d779f85c40d9a076b8151aa4303e49a01

Maybe you can try re-emerging it to see if you gain 8.4 support

[Comment 10 Alexey Korepanov 2020-06-27 10:15:42 UTC]

re-emerging cuda helped! The problem is indeed the missing revbump.
