Suitesparse /Cuda SBo, complains about too advanced GCC, although being built with GCC 5 from the same SBo.

Hello, everyone.

I'm trying to build suitesparse from SBo.
I am using the latest -current with a handful of packages, including gcc-5, cuda and nvidia-legacy390

I tried sourcing /etc/profile.d/gcc5.sh in the shell, and in the slackbuild itself, but to no availd. The build script still complains about being run with a wrong GCC:

Code:

gcc-5    -O3 -fexceptions -fPIC -fopenmp -DGPU_BLAS  -c -I../../AMD/Include -I../../AMD/Source -I../../COLAMD/Include -I/tmp/SBo/SuiteSparse/CCOLAMD/Include -I/tmp/SBo/SuiteSparse/CAMD/Include -I/tmp/SBo/SuiteSparse/metis-5.1.0/include -I../Include -I../../SuiteSparse_config -I/usr/share/cuda/include/ ../GPU/cholmod_gpu.c

Any tips?

Complain upstream.

Upstream wouldn't care, because CUDA 8 is already old.

I ended up just adding lines:

Code:

-ccbin $CC \

-gencode=arch=compute_20,code=sm_20 \

to SuiteSparse_config/SuiteSparse_config.mk

at the line 246, but I'm too ignorant to send a patch to SBo.

What is the issue with using newer supported versions then?

You can contact the SBo maintainer by the e-mail listed in the info file.

The issue is that my card, GF119, is not supported by CUDA9, moreover, CUDA8 is available at SBo.

Just in case. No guarantees, but I did manage to build the package.
