Hi and welcome to devnet,

Qt 5.12.1 got released a few days ago, can you try with that one ?

for any ubuntu 18.04 users (like me) finding this discussion through web search... don't use the ubuntu QT install from apt-get, instead install open-source-QT from the QT website. It's installer program will install binaries, including qt-for-android into it's own subdirectory.

Hi,

Is it possible to customize the Boot to Qt system to add the Xenomai features?

My problem is that I have an application working on Vxworks with a very old graphical environment and real time constrains (< 1ms). Now I have to replace the old GUI by a new one, using Qt, but keeping the existing real time functions. The low layers of my application work fine on linux with Xenomai.
My goal is to have the GUI (Qt/Qml) running in the main process connected with a second process, executed on a second core, using Xenomai to execute the low layres of my application with its real time constrains.

Is-it possible to do that with Qt for device creation and Boot to Qt?

Thanks.

I was trying to upgrade my Centos 7.5 Dockerfile from using 5.12.0 to 5.12.1.

The only thing that I change in the Dockerfile were the version numbers (5.12.0 to 5.12.1) in the following lines:

#install qt5.12
ADD qt-installer-noninteractive.qs .
RUN wget -q http://download.qt.io/archive/qt/5.12/5.12.1/qt-opensource-linux-x64-5.12.1.run
RUN chmod +x qt-opensource-linux-x64-5.12.1.run
RUN ./qt-opensource-linux-x64-5.12.1.run --platform minimal --script qt-installer-noninteractive.qs --verbose

RUN /opt/Qt/Tools/QtCreator/bin/qbs setup-toolchains --detect 
RUN /opt/Qt/Tools/QtCreator/bin/qbs setup-qt '/opt/Qt/5.12.1/gcc_64/bin/qmake' QtProfile
RUN /opt/Qt/Tools/QtCreator/bin/qbs config profiles.QtProfile.baseProfile clang

ENV PATH="/opt/Qt/5.12.1/gcc_64/bin:${PATH}"
ENV LD_LIBRARY_PATH="/opt/Qt/5.12.1/gcc_64/lib:${LD_LIBRARY_PATH}"

Now when I run a very basic application (just a empty QMainwindow) using a docker-compose file it crashes.

I saw in another post here on the forum that suggested using QT_DEBUG_PLUGINS=1
Where I got the following error message:

application-run        | Got keys from plugin meta data ("xcb")
application-run        | QFactoryLoader::QFactoryLoader() checking directory path "/home/polaris/bin/platforms" ...

I've tried all the suggestions in the post that I linked to above, and non of them fix this problem.

Again this application runs fine on Qt 5.12.0.

I'm trying to use QTCharts 2.1.0 for QT 5.4.1 version. I use opensource QT and tried to install QTCharts as the instructions shown in this qtcharts github release-2.1.0 link

I build without any problems but when I try to run it with nmake I get the exception shown belown and I genuinely have no idea about the reason. So, I'd appreciate any help. I'm using VS2012 x86 Native Tools Command Prompt btw.

Greetings everyone. I'm needing to get the nativeHandle for a QOpenGLWidget in order to set up initialisation for some OpenCL (note: CL, not GL) functions. As I am on Mac, it seems I need to include some specific Qt headers.

#include <QtPlatformHeaders/QCocoaNativeContext>

However, in QtCreator it doesn't seem to be finding these specific platform headers.
I can confirm my Qt installation contains them at: (MyQtDir)/5.12.1/clang_64/include/QtPlatformHeaders/

I have also tried

#include <QCocoaNativeContext>

as indicated here: https://doc.qt.io/qt-5/qcocoanativecontext.html

I figured it was perhaps a missed Add-On, but I've looked in the Maintenance Tool -> Add / Remove Components... but I don't see any items that either refer to this QtPlatformHeaders Add-On module directly.
https://doc.qt.io/qt-5/qtplatformheaders-index.html

Sadly I'm at something of a loss as to how to resolve this.

Hi all,

I would like to build QT in debug mode on Win10 with MSVC with compiler option /D _ITERATOR_DEBUG_LEVEL=0
Could you please help me where or how should I set the flag. Preferably only once for all QT modules.
IMHO there isn't option for setting CXXFLAGS in configure.bat

Thanks

Hello,
I'm working on the installation of qt for cross-compiling.
For the installation I followed tho wiki:
https://wiki.qt.io/RaspberryPi2EGLFS
The Qt-Version is: 5.10.1 for raspberry#zero w
On step 10 I tried to execute the following command:
./configure -release -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot ~/raspi/sysroot -opensource -confirm-license -make libs -prefix /usr/local/qt5pi -extprefix ~/raspi/qt5pi -hostprefix ~/raspi/qt5 -v
But I got an error
You don't seem to have 'make' or 'gmake' in your PATH.
Cannot proceed.
This is my PC:
Ubuntu 18.04.2 LTS
4.15.0-29-generic x86_64

Please could somebody give me a solution?
Thanks in advance.

Download the source code of qt5.6.3

• http://download.qt.io/archive/qt/5.6/5.6.3/single/qt-everywhere-opensource-src-5.6.3.tar.xz

Compile error, command as follows

./configure -static -debug-and-release -nomake examples -nomake tests -prefix ~/Qt/5.6.3_static_osx -qt-sql-sqlite -plugin-sql-sqlite -qt-libpng -qt-libjpeg -qt-zlib -qt-pcre -opensource -confirm-license -opengl -qt-freetype

Make error, modify the qtbase/src/plugins/platforms/cocoa/qcocoahelpers.mmfile before execution

Perform make is not an error, but make install error

How do I compile correctly？

I solved the problem. Actually this is the linker error. Some required libraries were missing, so I added them as per the Readme document of the GLG toolkit(for C++).
I installed the compatible GLG program and in .pro file of Qt program the library path was properly included as :
INCLUDEPATH += . /opt/glg3.7/include #comment (this line includes the header files)
LIBS = -L/opt/glg3.7/lib -lglg_x11 -lglg_map_stub
-lXt -lX11 -ljpeg -lpng -lz -ldl -lXft -lfontconfig -lfreetype #comment (-L includes the library folder and -l include the libraries itself)

Hi,
i am running iMx6 with Debian and trying to configure Qt5.12.0.
So this is my configuration:

-qpa eglfs \

QMAKE_LIBDIR_OPENVG=/usr/lib QMAKE_INCDIR_OPENVG="/usr/include" \
-DEGLFS_DEVICE_INTEGRATION=eglfs

this is the issue:

ERROR: Feature 'opengles2' was enabled, but the pre-condition 'config.win32 || (!config.watchos && !features.opengl-desktop && libs.opengl_es2)' failed.

ERROR: Feature 'eglfs' was enabled, but the pre-condition '!config.android && !config.darwin && !config.win32 && features.egl' failed.

ERROR: The OpenGL functionality tests failed!
You might need to modify the include and library search paths by editing QMAKE_INCDIR_OPENGL[_ES2],
QMAKE_LIBDIR_OPENGL[_ES2] and QMAKE_LIBS_OPENGL[_ES2] in the mkspec for your platform.

Hello !

I'm trying to install "serialbus" module. Because, I would like to code a communication between two devices with modbus protocol.

But it doesn't work.

I'm working with :

• Linux Mint 18 OS
• Qt creator 4.5.2 based on Qt 5.9.5

Here, my Build & run's configuration :

I don't know what linux package to install.

Thank you for your help.

Hello,
with your help I got qt running on my UBUNTU-PC and I also can remotely create software for a raspberry#Zero-w.
But now I can't debug.
As I start debugging I get the following error:
The selected build of GDB does not support Python scripting.
It cannot be used in Qt Creator.
I found something that I need to install gdb-multiarch on Ubuntu. s this correct? and where I have to setup the GDB?
Who can give me some help?
Kurt

I am new to qt. I just install qt tools for visual studio 2017 but when ever I try to create a project it returns an error dialog saying "Object reference not set to an instance of an object". Thanks in advance.

@Peter.Chorn

How did you managed to import the Dir component?

In QIF 3 dynamic page example, there is the following definition (installscript.js):

@SGaist Ahh, okay I see it.

Clone Build Config -> Delete Build Steps -> add Custom Process Step

Thanks for the inspiration!

You found a solution "Add Repositories". Have you succeeded populating that repository list via that button? I would imagine that it is impossible for anyone needing the installer in the first place.

Hi,

I just installed Qt 5.12 with MinGW 7.30 64bit (and VS2017 64bit). Qt Creator auto detects both compilers and generates the kits, but for MinGW it identifies the wrong directories to the compiler/debugger (32bit instead of 64bit).
Is there a way to change it? I temporary resolved it by renaming the dir in the Qt installation directory, but I would like my auto detected kits to point to the intended dirs :)
Thanks for the help,

Jan
