Also I think it was decided that in Qt5 we can remove support for -no-x11extenssion-name switches in the Qt configure script. There is always -qt-xcb available if your distro does not provide the required dependencies. And it does not add any value not to compile-in the extension code. It should be a runtime decision, if X server has an extension available, we use it. ________________________________________ From: development-bounces+gatis.paeglis=theqtcompany....@qt-project.org <development-bounces+gatis.paeglis=theqtcompany....@qt-project.org> on behalf of Александр Волков <a.vol...@rusbitech.ru> Sent: Friday, October 16, 2015 2:02 PM To: Knoll Lars; Thiago Macieira; development@qt-project.org Subject: Re: [Development] Updating the minimal supported version of libxcb 16.10.2015 09:28, Knoll Lars пишет: > On 15/10/15 17:59, "Thiago Macieira" <thiago.macie...@intel.com> wrote: > >> On Thursday 15 October 2015 18:26:23 Александр Волков wrote: >>> Hi, >>> >>> Currently Qt supports libxcb 1.5, which is very old (it was released on >>> December 3, 2009) >>> It complicates adding new bundled xcb libraries, because they have to be >>> checked >>> for compatibility with this old version and maybe patched. >>> >>> Qt officially supports the following platforms that use libxcb: >>> OpenSuSE 13.1 (libxcb 1.9.1, xcb-proto 1.8) >>> Red Hat Enterprise Linux 6.6 (libxcb 1.9, xcb-proto 1.8) >>> Ubuntu 14.04 - 64bit (libxcb 1.10, xcb-proto 1.10) >>> >>> What do you think about updating the minimal supported version of libxcb >>> to 1.9? >> Unless it's critical, let's do it only in 5.7. > Yes, I don’t know of larger issues that would require a change in 5.6.

With libxcb 1.9 they are all provided by the supported distros. The only exception is xcb-xkb, which we require to be from libxcb 1.10. So my proposal is to remove them from Qt, remove configure options -qt-xcb and -system-xcb, and use the bundled xcb-xkb library if we can't find the appropriate version on the system. _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
