Error compiling suitesparse package on Pop!_OS 19.10

[Olivier Guillon]

Hello,

while trying to compile the last develop version of sagemath, my Pop!_OS machine failed to build suitesparse package

it seems like the CUDA toolchain on Pop!_OS 19.10 does not accept gcc compiler with version superior to 7. I got the following error :

-------------------------------------------------------------------------------------------------------------------------------------------------------
In file included from /usr/lib/cuda/include/cuda_runtime.h:83,
                 from <command-line>:
/usr/lib/cuda/include/crt/host_config.h:129:2: error: #error -- unsupported GNU version! gcc versions later than 7 are not supported!
  129 | #error -- unsupported GNU version! gcc versions later than 7 are not supported!
-------------------------------------------------------------------------------------------------------------------------------------------------------

Any clue for a workaround ?

Thanks.

To be honest, I thought turning on using the GPU required manual intervention. Obviously it was turned on automatically for you. 

I'll get a ticket to fix this.

In the meantime do

CUDA=no make suitesparse

and it should build

Thanks a lot for the quick answer !!! Will try it and report result. Actually I was in the process of building the package with the gcc version that came with CUDA (gcc6), but I must admit my total lack of positive outcome so far...

So "CUDA=no make suitesparse" didn't do the trick. I had to purge the whole CUDA toolchain to finally get a build, then reinstall CUDA...and now sage is up and running !

I should have mentionned that the physical machine is a dell xps 15 (9560) with hybrid graphics and Pop!OS 19.10 which untill now really did the job flawlessly,

but I'm seriously thinking jumping back to Archlinux where I didn't get any such collision between sage and cuda.

Once again thanks for answering so quickly, I might still be struggling with my idea  of building it with gcc6 (started building the whole source with it, which just brought more problems...).
