[Interest] Qt-5.11.0 - QtWebEngine Compilation Broken for Windows 32-bit Builds

[coroberti .]

Hi,

I was trying to follow the recommendations of Kai by:


1. Using the cross compiler and running in MSVC prompt:

"C:\Program Files (x86)\Microsoft Visual
Studio\2017\Community\VC\Auxiliary\Build\vcvarsamd64_x86.bat"

2. Configuring qt-5.11.1 as:

configure -prefix C:\\Users\\robert\\dev\\qt-5.11.1-webeng-build
-shared -opensource -platform win32-msvc -nomake tests -nomake
examples -skip qt3d -skip qtactiveqt -skip qtcanvas3d -skip
qtconnectivity -skip qtdatavis3d -skip qtlocation -skip qtmultimedia
-skip qtscript -skip qtsensors -skip qtserialport -skip qttranslations
-no-opengl -no-openvg -qt-zlib -qt-libpng -qt-libjpeg -no-avx -no-avx2
-openssl -I C:\Users\robert\dev\OpenSSLShared\include -L
C:\Users\robert\dev\OpenSSLShared\lib


3. Running nmake.

All compilation of qt including qtwebengine passes properly (with nmake /I)

but with compilation error at one module that seems to be dependent on openGL?

See the below:

C:/Users/robert/dev/qt-src-5.11.1/qtwebengine/src/core/web_engine_context.cpp(190):
error C2027: use of undefined type 'QOpenGLCon
text'
c:\users\robert\dev\qt-src-5.11.1\qtbase\include\qtgui\5.11.1\qtgui\qpa\../../../../../src/gui/kernel/qplatformnativeinterface.h(6
0): note: see declaration of 'QOpenGLContext'
C:/Users/robert/dev/qt-src-5.11.1/qtwebengine/src/core/web_engine_context.cpp(190):
error C3861: 'openGLModuleHandle': identifier not found


Is it correct to say that qtwebengine cannot be compiled without
openGL or this is some additional bug in Qt?

Thanks in advance!

Kind regards,
Robert
