How to deploy when using Resource System? (Windows 10)
-
Hello,
i am new with Qt and heve develop my first program.Now i want to run my program stand alone without the Qt Creator.
I put
libgcc_s_seh-1.dll, libstdc++-6.dll, libwinpthread-1.dll
Qt5Core.dll, Qt5Gui.dll, Qt5Widgets.dll
and the plugin folders
imageformats, platforms, printsupport, styles
into the working directory.The program is nearly fine, but the images, that i put into Qt Resource System will only shown when its start throw the Qt Creator.
Wenn it is start direct from the working directory the images are not shown, all other work, but not the images from the Qt Resource System.I use Qt5.14.0, mingw73_64, Windows 10
what can i do?

thanks jsulm,
yes, i readed this many time but i unterstand it not full, i am a beginner in Qt.
The windeployqt doesn't tell what plug-ins is needed.
Even when i copy all plug-ins folders into the working directory my jpg-files are not loaded.
Maybe there is a format problem to my jpg-filesI think, i have the needed plug-in to handle jpg, all I/O opterations (store, ..) with jpg that are calculated by the program works.
Wenn i use *.png images in the QRessource System it works fine, even from cmd.exe
So i have changed to the *.png format.to me it is all fine, further i use png format
thanks jsulm to your help

Can you show how you're using your resources?
Also, do you see any warnings when you start your app from cmd.exe? -
hello jsulm
i use a *.qrc (jack-ressourcen.qrc) over the Qt Creator
<RCC>
<qresource prefix="/images">
<file>ressourcen/jack-logo.jpg</file>
<file>ressourcen/Startbild.jpg</file>
<file>ressourcen/JACK-mittel.jpg</file>
<file>ressourcen/JACK-groß.jpg</file>
</qresource>
</RCC>in the source code i use the ressources
...
QImage imageLogo(":/images/ressourcen/jack-logo.jpg","JPG");
...
ui->label_imageLogo->setPixmap(QPixmap::fromImage(imageLogo));
...When i rum with Qt Creator (debug or relase) it works the imageLogo is displayed.
Whan i run from cmd.exe there ist no error, the program works, but the imageLogo is not shown.
A image, that i generate by QPainter thru the Program is shown, there no problem running from CMD :
...
QImage imageSchablone(2480, 3508, QImage::Format_RGB32);
...
// calculating the image
imageSchablone = aktSchablone.berechnen(aktuellerTonarm);
....
// show the image
// PixMapSchablone is a lable on the ui
ui->PixMapSchablone->setPixmap( QPixmap::fromImage(imageSchablone).scaledToHeight(900));
... -
I have testet with aditional images in the QRessource System.
The progam.exe get bigger, so i think the images are link into the program.... but the the images are not shown when i rum from cmd.exe
-
also show a image direct from file only work when run from Qt Creator (Debug or Release), wenn run from cmd.exe the image is not shown.
...
QImage imageStartSeite("D:\QT-Creator-Projekte\JACK-Tool\Startbild.jpg","JPG");
... -
also show a image direct from file only work when run from Qt Creator (Debug or Release), wenn run from cmd.exe the image is not shown.
...
QImage imageStartSeite("D:\QT-Creator-Projekte\JACK-Tool\Startbild.jpg","JPG");
...@Ijon_Tichi I think your problem is that you do not deploy your app properly before starting outside of QtCreator, so it can't find needed plug-in.

@Ijon_Tichi So, did you actually use windeployqt tool? It should copy the plug-in. Also, the plugins need to bi in a subdirectory as shown in the above link in an example:
The executable plugandpaint.exe The Basic Tools plugin plugins\pnp_basictools.dll The ExtraFilters plugin plugins\pnp_extrafilters.dll The Qt Windows platform plugin platforms\qwindows.dll The Qt Windows Vista style plugin styles\qwindowsvistastyle.dll The Qt Core module Qt5Core.dll The Qt GUI module Qt5Gui.dll The Qt Widgets module Qt5Widgets.dll -
as i wrote in Post 1
i put
libgcc_s_seh-1.dll libstdc++-6.dll libwinpthread-1.dll Qt5Core.dll Qt5Gui.dll Qt5Widgets.dlland the plugin folders
imageformats platforms printsupport stylesinto the working directory.
but even when i copy all plug-in folders into the working directory there is the trouble with the jpg.
where can i find information, what plug-ins more than "imageformats" are needed to handle jpg?
as i wrote in post 2 i use the windeployqt tool, i have set the env (qtenv2.bat) bevor:
windeployqt Output:
D:\QT-Creator-Projekte\build-JACK-Tool-Desktop_Qt_5_14_0_MinGW_64_bit-Release>windeployqt --release JACK-Tool.exe D:\QT-Creator-Projekte\build-JACK-Tool-Desktop_Qt_5_14_0_MinGW_64_bit-Release\JACK-Tool.exe 64 bit, release executable Direct dependencies: Qt5Core Qt5Gui Qt5Widgets All dependencies : Qt5Core Qt5Gui Qt5Widgets To be deployed : Qt5Core Qt5Gui Qt5Widgets Unable to find the platform plugin.searching to the error message "Unable to find the platform plugin", i doesn't found a solution
I thing the ressource system work fine. By using png format it works fine.

@Ijon_Tichi said in How to deploy when using Resource System? (Windows 10):
Unable to find the platform plugin.
To solve the problem with the windeployqt i downloaded the windeployqt64releaseonly.exe from here: http://tripleboot.org/Uploads/windeployqt64releaseonly.zip
