With GPLv2 only. But most interestingly, GPLv3 states: "Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require" Technically, there's nothing in FlexiBLAS that a BLAS/LAPACK application would require to work. These are designed to require BLAS/LAPACK, and FlexiBLAS just duplicates that interface and glues symbols together. Maybe I'm completely misunderstanding the sentence above, but GPL restrictions of course apply to any program that uses the FlexiBLAS API for profiling, etc., but not to those that just use the BLAS/LAPACK API. -- Iñaki Úcar _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx
