clone emsdk

git clone https://github.com/juj/emsdk.git
cd emsdk
./emsdk install --build=Release sdk-incoming-64bit binaryen-master-64bit
./emsdk activate --build=Release sdk-incoming-64bit binaryen-master- 64bit
source ./emsdk_env.sh --build=Release

clone QT source code

cd ~/job/
git clone https://github.com/qt/qt5.git
cd qt5/
git checkout origin/ version here
perl init-repository --berlin --module-subset=default,-qtwebengine
cd ~/job/qt5
./configure -xplatform wasm-emscripten -nomake examples -prefix $PWD/qtbase
make module-qtbase module-qtdeclarative module-qtcharts

Build example using QT charts

cd projectdir
 ~/job/qt5/qtbase/bin/qmake ; make
