How to build QtWebEngine?



  • I downloaded qtwebengine-opensource-src-5.7.0.tar.gz and compiled successfully,but when I run a webengine example ,it reports error like below:
    Qt WebEngine ICU data not found at /usr/local/Qt-5.7.0/resources. Trying parent directory...

    hope for your guy's reply and help!!!!!



  • @JayLu said in Qt 5.7 Linux x86 how to build QtWebEngine?:

    Installed Qt WebEngine locales directory not found at location /usr/local/Qt-5.7.0/translations/qtwebengine_locales

    You are supposed to have a bunch of *.pak locale files in /usr/local/Qt-5.7.0/translations/qtwebengine_locales. You seem not to have them there. Check whether/where you do have them, and look at how you're supposed to "install" properly for QtWebEngine after compiling it.



  • I use Windows and msvc 2015 compiler.
    I Installed a qt-opensource-windows-x86-5.9.2.exe. Then I changed a very little some headers in qtwebengine module. Then, I need to rebuild it. I opened configurated by Qt console for msvc2015 x86_64 compiler, go to the src/qtwebengine, typing qmake and after that nmake. nmake only outputs

    Microsoft (R) Program Maintenance Utility Version 14.00.24210.0
    Copyright (C) Microsoft Corporation.  All rights reserved.
    

    but did nothing.
    I downloaded qtwebengine-opensource-src-5.9.2 separately and try to buid it - the same result.
