IIRC the designer isn't built with mingw, thus it can*t load mingw dlls. Check the Info window in the designer, there should be the used compiler specified. I believe its some msvc variant.

Unsolved Qt Application crashes on startup
Are you using and Intel HD Graphics video card? I've noted they broke the driver for OpenGL https://communities.intel.com/message/521599#521599 but it's a big blackhole trying to get fixed.
If you specify:
// MSVC17 / Intel driver bug - use angle QGuiApplication::setAttribute(Qt::AA_UseOpenGLES, true);before QApplication ... does that get you working?
It's a bit shit cause I believe you lose anti-aliasing - I've just put MSVC compiler builds/branches low for now and am using GCC in linux and MinGW5.3.0 to further development.
I'd try using another compiler just to see if you can get moving again.

Solved Qt 5.9.2 cross-compiled: host errors
@AlTro Was there any resolution to your problem? I found a Qt-Bug that very likely seems to be related, but it was issued and already "resolved" in 5.9 and I'm cross-compiling with 5.10, so this specific bug should be solved.

Unsolved Qt 5.9.2 build error (Mac)
I can't seem to get Qt 5.9.2 to build...
qtbase/src/corelib/kernel/qcore_foundation.mm:491:13: error: static_cast from 'CFTimeZoneRef' (aka 'const __CFTimeZone *') to
'NSTimeZone *' is not allowed
return [static_cast<NSTimeZone *>(toCFTimeZone()) autorelease];
The code for method:
NSTimeZone *QTimeZone::toNSTimeZone() const
{
return [static_cast<NSTimeZone *>(toCFTimeZone()) autorelease];
}
is the same up to the latest Qt so I'm guessing the problem is with my specific compiler/os. Has anybody else run across this issue? Is there a possible workaround that only involves a code change (and not upgrading OS/compiler)? I'm willing to remove any feature or module needed to get this built.
The Apple Developer documentation says that NSTimeZone and CFTimeZoneRef are interchangeable but I'm not at all familiar with Objective-C.
I have also tried disabling timezone features while configuring but it leads to even more build errors. I noticed that the code always checks for
!defined(QT_NO_SYSTEMLOCALE)
but I can't find where to set that while configuring.

Unsolved Customizing maintenance tool
Hey all,
Is there a way to customize the buttons at the end of the maintenance tool? Currently I have it running and updating my program which is great, but at the end there are two options
- Restart
- Quit
Right now restart restarts the maintenance tool and not my program which is a bit counter intuitive. I'd like to either remove the restart button or configure it to launch the new version of my program. All I can find about customizing maintenance tool is this
https://doc.qt.io/qtinstallerframework/ifw-component-description.html
which mentions an ini file, but doesn't link ot anything useful or even mention what the ini file does.

Unsolved Qt 5.9.4 For ARM
Hey guys, so i'm using Ubuntu 16.04 and i would like to make Qt for my embedded linux (which is Mini6410). I do have Qt 4.7 installed and running with to following ./configure: "./configure -opensource -embedded arm -xplatform qws/linux-arm-g++ -qt-libtiff -qt-libmng -qt-mouse-tslib -qt-mouse-pc -no-mouse-linuxtp -no-neon".
The problem is that qws isn't present in Qt 5 and above. I do have a cross compiler (tool chain) installed. Can anyone help? Appreciate the attention.
