How to add new module? RaspberryPi2EGLFS

[defs]

I am not sure how to add new module for cross-compiling according to this tutorial:
https://wiki.qt.io/RaspberryPi2EGLFS

There is step 13 which says:

13. Build other Qt modules as desired, the steps are the same always:

~/raspi/qt5/bin/qmake -r
make
make install

but where can I get source for wanted module? I want QML and QUICK module to be installed.

I tried to clone this repo : https://code.qt.io/cgit/qt/qt5.git,
then went to qtdeclarative folder and run first two commands from step 13.:

~/raspi/qt5/bin/qmake -r
make

but after few minutes I got error:

../qsgdefaultdistancefieldglyphcache.cpp: In member function ‘virtual void QSGDefaultDistanceFieldGlyphCache::requestGlyphs(const QSet<unsigned int>&)’:
scenegraph/qsgdefaultdistancefieldglyphcache.cpp:107:100: error: ‘QT_DISTANCEFIELD_TILESIZE’ was not declared in this scope
         QSize glyphSize(glyphWidth + padding * 2, QT_DISTANCEFIELD_TILESIZE(doubleGlyphResolution()) + padding * 2);

What am I doing wrong?

Did you rerun configure bevor qmake the module? Also note that some modules depend on other modules. I cloned the qt5.git without webkit and webengine. It compiled fine.

git clone https://code.qt.io/qt/qt5.git
perl init-repository --module-subset=default,-qtwebkit,-qtwebkit-examples,-qtwebengine

I am having the exact same question. I followed the same post successfully and now want to use the serial module ON THE PI. So I apt-get the libqt5serialport5 successfully on the Pi and then sync to sysroot on my Ubuntu16 host. But still the build with the RPI kit shows error: Unknown module(s) in QT: serialport.
Do I need to compile the Qtserial module? If so, how?

Best regards

@sly110 Yes you need to cross-compile the module.

mkdir build_qtserialport
pushd build_qtserialport
/path/to/cross-compiled/Qt/qtbase/bin/qmake /path/to/Qt/sources/qtserialport/
make
make install
popd
rm -r build_qtserialport
