It's work okay after I add to the $PATH:
/opt/rh/devtoolset-6/root/usr/bin/gcc
Thanks

That tells you what your CPU is capable of. We need to know whether cmake
has found the compiler that can issue the instructions. Follow the
suggestions Roland and I have made.

How can I make GROMACS use devtoolset-6?
[shlomit@cn gromacs-2019.5]$ type gcc
gcc is /bin/gcc
[shlomit@cn gromacs-2019.5]$ scl enable devtoolset-6 bash
[shlomit@cn gromacs-2019.5]$ type gcc
gcc is /bin/gcc

Good, so is Cmake using it? (e.g. remove the build dir and run cmake again
to see what it first reports, or inspect $builddir/CMakeCache.txt for the
compiler setting)

installed, but not using it?
I ran:
cat /proc/cpuinfo | grep -i avx512
and got:
avx512f avx512dq avx512cd avx512bw avx512vl
So I thought I can use it. Am I wrong?

Hi,
What hardware are you targeting? Unless you need AVX512 support, you could
just manually specify the appropriate setting in GMX_SIMD, e.g.
-DGMX_SIMD=AVX2_256 would be appropriate for most cases where AVX512 is not
supported.
Cheers,

Hi,
I tried to install GROMACS 2019.5 on CentOS7,
cmake .. -DGMX_BUILD_OWN_FFTW=ON -DREGRESSIONTEST_DOWNLOAD=ON
I have already installed devtoolset-6 and still get this error:
