求助,Linux发布Qt WebEngine程序无法打开,如何解决?
Deploying Qt WebEngine Processes
Qt WebEngine takes advantage of the multi-process model that the Chromium project offers. The multi-process model requires that the Qt WebEngine Process executable be deployed alongside your application.
The WebEngine process is executed for each QWebEngineView or WebEngineView instance. For example, a browser application with two tabs open should have two separate instances of the process running. This is a common approach used by most modern web engines to provide a stable browsing experience.
At runtime, Qt WebEngine looks for the QtWebEngineProcess executable in the directory that QLibraryInfo::location(QLibraryInfo::LibraryExecutablesPath) returns. For Qt installations, this is QTDIR/libexec (Linux) or QTDIR\bin (Windows). The path can be changed by defining a qt.conf file, for example. Alternatively, an executable path can be set as a value of the QTWEBENGINEPROCESS_PATH environment variable. On macOS, Qt WebEngine looks for the executable in .app/Helpers/QtWebEngineProcess.
Deploying Resources
Qt WebEngine requires the following resource files:- qtwebengine_resources.pak contains the resources needed by Chromium.
- qtwebengine_devtools_resources.pak contains tools for remote debugging.
- qtwebengine_resources_100p.pak contains images suitable for low resolution displays.
- qtwebengine_resources_200p.pak contains images suitable for high DPI displays.
- icudtl.dat provides support for International Components for Unicode (ICU). It is the Chromium version of ICU, which is not needed if Qt WebEngine was configured to use the system ICU.
Resources are searched from the following locations:
