We are very excited to announce that new compilers based on repackaged
sysroot's from CentOS 7 are now available for all linux-* platforms.
These compilers will be the default going forward for any gcc, gxx,
and gfortran versions past 8.4.0 on ppc64le and 7.5.0 on
x86_64/aarch64.
On the linux-64 platform, we have also built the CentOS 6 sysroot
and set it as the default, consistent with our current compilers. To use
the CentOS 7 sysroot on linux-64, add a requirement of
sysroot_linux-64 2.17 to the build section of your recipe. You also
need to set the proper Docker image in your conda_build_config.yaml.
See Using CentOS 7 <centos7> for details.
