FWIW, Denis: I feel your pain and agree that the Qt Company and Qt Project have a responsibility to make cross compilation with CMake just work out of the box when you have the necessary kits installed in QtCreator.
There is absolutley no excuse for us not doing this. We as a company should be very careful to make this work as developers who *use* Qt won’t care at all if CMake causes them to lose time resetting up their tool chains for cross compilation. I have also noticed that CMake does not work out of the box with many of our Boot2Qt kits. Needs fixing ASAP. ________________________________ From: Development <development-boun...@qt-project.org> on behalf of Denis Shienkov <denis.shien...@gmail.com> Sent: Thursday, December 13, 2018 4:59 AM To: chg...@gmail.com Cc: development@qt-project.org; kevin.kof...@chello.at Subject: Re: [Development] CMake && QtCreator cross-compilation for ARM fails > And it would be much worse for QBS, which requires much more from Qt than > QMake. It requires QML, JavaScript, etc. So what? A GCC too compiles with GCC... For me, as a developer it is not a big problem and not a my. A worse problem is in CMake's ideology. QBS just work immediatelly! Unlike of CMake! And a fact that the QBS's just work cover all CMake's bootstrap crap. CMake has no one agvantage for developers! чт, 13 дек. 2018 г. в 15:02, Denis Shienkov <denis.shien...@gmail.com<mailto:denis.shien...@gmail.com>>: > Once you have the cross toolchain configured properly, which is a one-time > setup effort, CMake will just work, too. Will just work? What??! HAHA. Are you kidding? Why I need to configure something? Why I need to create an additional CMake's scripts, config files, toolchains and etc? I already have added all required cross-compilation stuff (toolchain && rootfs) to QtCreator. With QBS && QMake it works immediatelly! But for CMake I need in additional unknown things. And is it user friendly? The Qt's PR peoples (especially the CMake maintainers) are praised that they have added a lot of CMake && QtCreator integration improvements. But, I don't see any results related event to a simple cross-compilation issues! It is nonsense! How much the users need to wait for improvements for this (and other) issues with CMake? It completelly gets stuck for a working process. Where is CMake advantages? I see only regressions! And it is reality! чт, 13 дек. 2018 г. в 13:48, Christian Gagneraud <chg...@gmail.com<mailto:chg...@gmail.com>>: On Thu, 13 Dec 2018 at 12:27, Kevin Kofler <kevin.kof...@chello.at<mailto:kevin.kof...@chello.at>> wrote: Hi Kevin, > > PS: WTF?

Can you point me to something that shows the Qt "project" contributing to the Qt "company" on that very particular topic? The Qt Company has been looking for "employees" to work on Qbs for month before dropping it, apparently nobody responded, or something... > > From my point of view, the CMake it is a crap... > > CMake is not a "crap", it is a powerful tool, almost as easy to use as > QMake, but a lot more flexible and powerful. Cmake is crap, it is a macro based language, like it's good to be back in the 80's. It has no semantic, and no concept apart form 'macro', the syntax sucks, big time, every thing is just 'expression', read that one: https://cmake.org/cmake/help/latest/manual/cmake-generator-expressions.7.html#output-expressions And read that again and again, until you brain says: 'Actually, CMake is "crap"!' > > > I know, that I'm not a CMake expert, but Why I need to spent a lot time > > to make the CMake working wich an unknown result, > > instead of just using QBS?

Oh yeah! Unless you hit some bugs, like, CMake-based cross-compilation doesn't actually exists (yet) on Windows: https://github.com/Kitware/CMake/commit/5f0f84c7e0630d7b8190c18badd5a68e2dd08ff7 I'm telling you: with CMake, it's 1988 Christmas, right now!
