Compatibility of GPLv2 and Apache v2 (OpenSSL again)
GPL software has an exception clause in order to link against OpenSSL
which has the advertising clause. Clamav for instance has this piece:
| In addition, as a special exception, the copyright holders give
| permission to link the code of portions of this program with the
| OpenSSL library under certain conditions as described in each
| individual source file, and distribute linked combinations
| including the two.
OpenSSL upstream now switched the license from BSD style to Apache
My understanding is that GPLv2 software can not be linked against Apache
v2 software due to the patent issue. GPLv3 (or GPLv2 or alter) can be
linked but that is not the issue here.
Can such an exception in GPLv2 software be used in order to link against
Apache v2 software or is this not possible anymore?
