Error while building qtwebengine module from Qt 5.7.0



  • Hello everyone.
    I tried to compile Qt 5.7.0 from source (link) with MSVS 2015 in both x86 and x64, but the process failed during the compilation of qtwebengine module.
    Errors were the following:

    [12804/12810] CXX obj\src\core\QtWebEngineCore.web_engine_settings.obj
    FAILED: ninja -t msvc -e environment.x64 -- cl.exe /nologo /showIncludes /FC @obj\src\core\QtWebEngineCore.web_engine_settings.obj.rsp /c %path_to_qt%\qt-everywhere-opensource-src-5.7.0\qtwebengine\src\core\web_engine_settings.cpp /Foobj\src\core\QtWebEngineCore.web_engine_settings.obj /Fdobj\src\core\QtWebEngineCore.cc.pdb

    NMAKE : fatal error U1077: '%path_to_qt%\qt-build\qtwebengine\src\3rdparty\ninja\ninja.exe' : return code '0x1'
    Stop.
    

    After that I tried to create web_engine_settings.moc and location_provider_qt.moc manually, and after restarting the compilation process I got another bunch of errors:

    ...
    

    My configuration file is:

    call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86
    SET _ROOT=%path_to_qt%\qt-everywhere-opensource-src-5.7.0
    SET PATH=C:\Perl64\bin;C:\Python\Python2711;%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH%
    SET QMAKESPEC=win32-msvc2015
    SET _ROOT=
    
    call ../qt-everywhere-opensource-src-5.7.0/configure -mp -ltcg -no-icu -opengl desktop -debug-and-release -force-debug-info -opensource -prefix "C:\Qt\Qt_5.7.0\MSVS_2015_x86\d-rt_d-lib" -confirm-license -nomake examples
    

    Is there a way to solve this problem?

    Thanks in advance.



  • I have the same error (also for Qt 5.6.0).
    Is there a solution ?



  • No. It seems to be a bug in Qt.



  • @horokey I'm having the exact same errors. Please let me know if you ever find the solution to this



  • Found the problem. It looks like during the initial stage of nmake, it was spitting out some errors complaining that the command line is too long. I found this ticket and patched those 3 files into my directory and it fixed the problem: https://codereview.qt-project.org/#/c/160622/

    Later down the line I experienced another compile issue (https://bugreports.qt.io/browse/QTBUG-54455) and patching this file fixed it: https://codereview.qt-project.org/#/c/163955/
