* Redistributions of source code must retain the above copyright notice, Modification, are permitted provided that the following conditions are met: Using a script and the information gained from the third step, copy the Qt files your application needs from your vcpkg tree and bundle them in with the application using a COPY command (or XCOPY.Redistribution and use in source and binary forms, with or without.And then compile your application against those same vcpkg Qt compiled libs (instead of Qt opensource.) Use vcpkg to compile all of the parts of Qt that your application needs.Note down exactly which files have been copied and their exact locations.Use windeployqt once the application has been compiled, to copy all the applications deps into a location containing a copy of the compiled application.
QT PLATFORM PLUGIN DOWNLOAD
QT PLATFORM PLUGIN WINDOWS
You should be using windeployqt if your platform target is Windows but unfortunately windeployqt does not work as expected when using Qt compiled via vcpkg. As a workaround for vcpkg, that can be set to %VCPKG%\installed\圆4-windows\debug\plugins\platforms (or the equivalent without debug). To override the platform plugin location, the environment variable QT_QPA_PLATFORM_PLUGIN_PATH can be set to any location. This is distinct to general Qt plugin loading which is more flexible. Contrary to some references, it doesn't use plugins\platforms (for Qt 5.12). The platform plugin is loaded from the directory named platforms relative to the application executable. Qt plugins can be redirected using qt.conf files, but this doesn't seem to be the case for the platform plugin. How best to do this will need to be determined by the vcpkg and Qt experts. Step 3 should result in a running Wireshark process. Running wireshark.exe asserts with This application failed to start because no Qt platform plugin could be initialized.Configured a build of wireshark (3.0.3) to use the Qt5 from step 1 compiled it.Installed Qt5 using vcpkg (qt5-base 5.12.3-3 along with other qt5-* pkgs needed for step 2: qt5-declarative qt5-modularscripts qt5-multimedia qt5-svg qt5-tools qt5-winextras.Is your feature request related to a problem? Please describe. This was reported as a comment to a closed issue months ago ( #2857 (comment)) but it seems to be its own issue. A Qt application built with vcpkg-installed Qt libraries fails at startup because the "Platform Plugin" can't be located.
