[[qanda:topic_solved]] Building with Gstreamer on Windows
I spoke too soon. I do have the application building but video is not yet playing. I was told that the issue may be because I am using MinGW rather than MSVC. I was able to trim down a sample application which I thought that I should share in case anyone else wants to give this a try. I see the video test pattern when I build it from QT Creator but not when I deploy it as a stand alone application. If you are able to see the test pattern as a stand alone application, please post here how you got it working. Thank you!

[[qanda:topic_unsolved]] QML plugins are not imported when using CMake and static Qt
Hello!
Recently I have been struggling with CMake & static Qt build.
Consider a very simple application written with QML:
import QtQuick 2.14
import QtQuick.Controls 2.14
import QtQuick.Window 2.14
Window {
visible: true
width: 640
height: 480
title: qsTr("Hello World")
Button {
anchors.centerIn: parent
text: "Button :)"
}
}
When I build this application using qmake everything works fine. I can run my app without any troubles, everything is packed inside executable. However, using CMake for the same project produces executable that not contain qml plugins (Error in runtime: QQmlApplicationEngine failed to load component qrc:/main.qml:1:1: module "QtQuick" plugin "qtquick2plugin" not found
My CMake file:
cmake_minimum_required(VERSION 3.5)
project(cmake_sample LANGUAGES CXX)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(BUILD_SHARED_LIBS OFF)
set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
find_package(Qt5 COMPONENTS Core Quick REQUIRED)
add_executable(cmake_sample
main.cpp
qml.qrc
)
target_compile_definitions(cmake_sample
PRIVATE $<$<OR:$<CONFIG:Debug>,$<CONFIG:RelWithDebInfo>>:QT_QML_DEBUG>)
target_link_libraries(cmake_sample
PRIVATE Qt5::Core Qt5::Quick)
To fix this I have to manually import & link all required QML plugins. While it solves the problem, it's very bulky on larger projects. I have the impression that these plugins should be automatically imported (others, like imageformats are ...)
Question: Is it intended in CMake or it is a bug? If it is intended, is there any correct and elegant solution to properly configure CMake project against static Qt?

[[qanda:topic_unsolved]] Want to add a embedded device to Host machine for QT5 as USB device
@Rathore You would first need to cross compile it for your device. Then deploy it to your device and run it there.
What device is that and do you have build tools (like compiler) and sysroot for it?

[[qanda:topic_unsolved]] What's the proper way to bisect qtbase on windows?
I'd like to know what's the proper way to bisect qtbase in order to find bugs without having to do cold builds over and over. Right now my extremely unefficient workflow to find qtbase bugs looks like this:
- I find a bug and I create a mcve
- I start bisecting
- I'll delete the current build folder (no ccache on windows), I'll configure and build again
- Test and if i didn't find the bad guy I'll back to 3)
As you may notice using this method is extremely slow/painful and not practical at all, on win7/msvc2017 using /j8 with no tests/examples each iteration is taking me ~1500s!!! That's nuts!
That said, I'm probably doing something clearly wrong here... so could you please advice to speed up the bug hunting?
Thanks in advance.

Slow downloads with the online installer? Try this tool
Fiddler-proxy with hostname-replacing helped me download from fastest mirror in my country.
I try this tool, but Qt Installer still download from download.qt.io (only local rep was enabled)
I past all links from this page http://download.qt.io/official_releases/online_installers/qt-unified-windows-x86-online.exe.mirrorlist in DownloadMaster and find the fastest server in Kazakhstan is mirrors.dotsrc.org
In Qt Installer settings I add proxy 127.0.0.1:8888
In Fiddler I change Customize Rules "OnBeforeRequest":
if (oSession.HostnameIs("download.qt.io") && oSession.PathAndQuery.StartsWith("/online/"))
{
oSession.hostname = "mirrors.dotsrc.org";
oSession.PathAndQuery = oSession.PathAndQuery.Replace("/online/", "/qtproject/online/");

I am planning to deploy my application to macOS and Windows. Upon reading the documentation of QT Installer Framework, I understand that I can provide a default installation path in the config xml which the user can overwrite.
In my application, I want to generate license files based on the installation path decided by the user. Hence, I need to have the installation path selected by the user passed to the application.
Is there a way that I can get the target installation directory selected by the user in the application.

[[qanda:topic_unsolved]] Cross-compiling Qt for ARM target not working - Need help
Hey everyone!
First a little background on what I'm trying to accomplish: I have an old eBook reader, a Tolino Shine to be exact, which I intend to use as a little status monitor, clock, calendar, etc. It's powered by a Freescale i.MX 5 processor and i've already managed to get Debian 8.11 running on it. I have to use such an old version because I'm stuck on kernel 2.6.35 and Debian 8 is the last version that will work with such an old kernel. Now I'd like to use Qt to build the software that's going to run on it and use the LinuxFB plugin to save some ressources by not having to run a X server in the background.
Now, I can't seem to figure out how to compile a Qt installation so I can build an application on my pc which I can then move to my target and run there.
I have already set up a fresh Ubuntu 18.04 VM with only build-essential, perl, python and g++-arm-linux-gnueabihf installed. On my target I have run "apt-get build-dep qt5-default" and installed the latest g++ available, which is 4.9. I then copied the whole filesystem of my target to a folder to use as sysroot. Am I doing this right?
I used this command to configure Qt:
./configure -device linux-tolino-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- -no-opengl -no-pch -no-xcb -linuxfb -sysroot ~/Desktop/sysroot -static -opensource -confirm-license
But I got a whole bunch of errors (log shorted):
vmuser@ubuntu:~/Desktop/qt_5.14.2$ ./configure -device linux-tolino-g++ -device-option CROSS_COMPILE=arm-linux-gnueabihf- -no-opengl -no-pch -no-xcb -linuxfb -sysroot ~/Desktop/sysroot -static -opensource -confirm-license -v

[[qanda:topic_unsolved]] Qtcreator build q5 from git
Linux Slackware-current
I built my qtcreator from source using cmake-gui because the qt.io package depends upon a glib2 version which I don't have.
GLib-CRITICAL **: 08:41:18.206: g_hash_table_contains: assertion 'hash_table != NULL' failed
Now I'm using qtcreator to build qt5 from git. (I can't find the 5.41.2 sources)
After searching high and low, I added "LICENSE.LGPLv3: to qt.pro. Now Build no longer waits for an 'o'. There is probably a way to send that option to the build process, but I don't know how. Of course it may take all day for the build, but it is running nicely. Just wanted to let others in my boat to know about the qt.pro license option.
