Re: Announcement: linux x86_64 builds on gfortran.org
Dear Manfred,
Many thanks for providing these builds. I wonder if the "Autopackage"
project could be of assistance in doing this.
http://www.autopackage.org/apbuild-apgcc.php
which allows building a more portable executable on a system with a
later GLIBC. I have used this on simple projects with some success,
though I imagine integrating with a compiler build would require
a little work, and I am not competent to judge the scope of this.
sincerely
Keith Refson
