Building qt from source on Nvidia Jetson Tx2

Dookei

Hi there,
I am trying to build from source qt 5.15 on a Nvidia jetson Tx2(armv8)
The make works just fine. But when I try the make install I get the error saying that the library libqtopenwnn.a is missing from the build directory(please see below).
Any thoughts on what I might be missing ?

+: error: /home/jetson/local_builds/qt_build/build/qtvirtualkeyboard/lib/libqtopenwnn.a: No such file or directory
make[5]: *** [Makefile:81: ../../../../plugins/virtualkeyboard/libqtvirtualkeyboard_openwnn.so] Error 1

This are my build steps:

git clone https://code.qt.io/qt/qt5.git
cd qt5
git checkout origin/5.15.2

perl init-repository --module-subset=default,-qtwebkit,-qtwebkit-examples,-qtwebengine,-qtsensors,-qtpurchasing,-qtcharts,-qtdatavis3d,-qtgamepad,-qtspeech,-qtlocation

cd ..
mkdir build
cd build
../qt5/configure -prefix /opt/Qt5.15.2 -opensource -confirm-license -optimized-qmake -developer-build -nomake examples -nomake tests

make -j4
make install

Please double check that your make -j4 call actually succeeds (that is , returns 0). You most likely have a compile error hidden in the log ...
