The code cmake --build . check in PKGBUILD doesn't work.

cmake --build . --target check works well for me.

@chn Ah thanks, this has worked for me!

@releddev I mean modify PKGBUILD file with export CC=gcc-8 and so on at about line 41.

@chn im experiencing the same error like you even after setting the environment variables as you've suggested. Any idea why that could be? I've checked the variables were set with printenv before makepkg -i and after installing gcc8 and fortran8.

@chn it looks like a regression with gfortran>=10. Let's continue discussion in issue thread on GitHub. As for now building with GCC8 is recommended

@diviktor Thank you for your suggestion about MAKEFLAGS.

This is the error when running makepkg -si, which seems caused in make install

@chn could you please provide more info about error messages? Also you shouldn't set -jX flag manually - be sure that you have proper MAKEFLAGS set in /etc/makepkg.conf - makepkg honors them

Hi,

The package will build failed with the last gcc (version 10). After switch to gcc-8, it works fine.

export CC=gcc-8
export CXX=g++-8
export FC=gfortran-8

What is more, building could take much less time with -j $ncore. In the last lines of build():

ncore=$(cat /proc/cpuinfo| grep "processor"| wc -l)
make -j $ncore
