    • Ubuntu 16.04

    Description

      Deployed application crashes as soon as started. I tried following approaches to deploy:

      1)

      • copying all Qt libraries next to application
      • removed Qt installation
      • changed rpaths of application executable, QtWebEngineProcess and platforms/libqxcb.so to point to the same directory
      • added qt.conf that contains: 
        [Paths]
Prefix = .

      2)

      • as above but without qt.conf
      • removed qt_prfxpath= from libQt5Core.so

      3)

      • both cases, qt.conf is present and modified libQt5Core.so

      4)

      • QTWEBENGINEPROCESS_PATH pointing to the QtWebEngine executable (see at the bottom)

      There is following output (#2):

      The important part is "Could not find QtWebEngineProcess" message. This comes from QtWebEngineProcess itself as we can see from output of these commands:

      strace -e write,execve,access,stat -f -o log ./untitled

21022 write(2, "Could not find QtWebEngineProces"..., 34) = 34

      Paths indicate that QLibraryInfo/applicationDirPath() returns nothing.

      When starting the application with QTWEBENGINEPROCESS_PATH, it does start, but renders nothing and throws this (perhaps because of resources not found as the environment variable is not considered in there?):
