It's technically possible, but not something you should expect us to do. For two reasons: 1) it's difficult OpenSSL API from 0.9.7 to 1.0.x did change and break binary compatibility, but the changes were minor. Most of the time, QtNetwork code was not affected and, when it was, it was easy to detect at runtime which version it was. That's not the case betwen 1.0 and 1.1: the extent of changes is very big and not easy to work around. In order to do this, we'd need BOTH sets of headers present at compile time and not a *single* Linux distribution provides a way to do that. 2) it's not worth it OpenSSL 1.1 and its ABI is the future. All modern Linux distributions have it, with most providing 1.0 for compatibility with software that has not recompiled yet. At this point, if you need to keep compatibility with older distros, I recommend using 1.0 and insisting that your user install their distro's 1.0 compatibility package. You'll only have problems with some "ultra modern" Linux distributions that have dropped 1.0 altogether. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
