Unsolved Plugin errors, & can't set path with qt.conf.
-
Hi all,
I'm building a Qt 5.7.0 application for the raspberry pi running Raspbian 4.9.59-v7+ #1047.
As an integrated solution, I'm using QtRpi for the prebuilt Qt binaries and toolchain, and have it configured as a kit in Qt Creator.
Everything builds fine, but I'm running into issues with deploying the app, specifically with the eglfs plugin. Running with QT_DEBUG_PLUGINS enables, I get the following relevant output:
QFactoryLoader::QFactoryLoader() checking directory path "/home/pi/platforms" ... loaded library "/usr/local/qt5pi/plugins/platforms/libqeglfs.so" QLibraryPrivate::loadPlugin failed on "/usr/local/qt5pi/plugins/platforms/libqeglfs.so" : "Cannot load library /usr/local/qt5pi/plugins/platforms/libqeglfs.so: (libts-0.0.so.0: cannot open shared object file: No such file or directory)" This application failed to start because it could not find or load the Qt platform plugin "eglfs" in "". Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, xcb. Reinstalling the application may fix this problem. Aborted
It's just confusing, as it seems all of the other plugins loaded just fine, ex:
QFactoryLoader::QFactoryLoader() looking at "/usr/local/qt5pi/plugins/platforms/libqlinuxfb.so" Found metadata in lib /usr/local/qt5pi/plugins/platforms/libqlinuxfb.so, metadata= { "IID": "org.qt-project.Qt.QPA.QPlatformIntegrationFactoryInterface.5.3", "MetaData": { "Keys": [ "linuxfb" ] }, "className": "QLinuxFbIntegrationPlugin", "debug": false, "version": 329472 } Got keys from plugin meta data ("linuxfb")
My guess is that it's because of the empty search path in the error message:
could not find or load the Qt platform plugin "eglfs" in ""
, but I can't seem to set that empty search path/folder. I've tried with a qt.conf in the application's directory, as per this documentation, but that doesn't seem to affect anything. Here's what I have:[Paths] Prefix = /usr/local/qt5pi/
Any thoughts/advice?
Thank you sincerely for the help.And a quick edit, as it may be unclear, the file it's claiming it can't find does exist. See:
pi@beta:~$ find /usr/local/qt5pi/plugins/platforms/ /usr/local/qt5pi/plugins/platforms/ /usr/local/qt5pi/plugins/platforms/libqeglfs.so /usr/local/qt5pi/plugins/platforms/libqminimal.so /usr/local/qt5pi/plugins/platforms/libqminimalegl.so /usr/local/qt5pi/plugins/platforms/libqxcb.so /usr/local/qt5pi/plugins/platforms/libqoffscreen.so /usr/local/qt5pi/plugins/platforms/libqlinuxfb.so

@teux said in Plugin errors, & can't set path with qt.conf.:
(libts-0.0.so.0: cannot open shared object file: No such file or directory)
you problem seems that the eglfs plugin doesn't load, because it can't find the dependency to libts?
