$ export WRSCOMPOSITOR=$HOME/install  
$ export LD_LIBRARY_PATH=$WRSCOMPOSITOR/lib  
$ export PKG_CONFIG_PATH=$WRSCOMPOSITOR/lib/pkgconfig/:$WRSCOMPOSITOR/share/pkgconfig/  
$ export PATH=$WRSCOMPOSITOR/bin:$PATH  
$ export ACLOCAL_PATH=$WRSCOMPOSITOR/share/aclocal  
$ export ACLOCAL="aclocal -I $ACLOCAL_PATH"

$ git clone git://anongit.freedesktop.org/wayland/wayland  
$ cd wayland  
$ ./autogen.sh --prefix=$WRSCOMPOSITOR        
$ make && make install

$ cd qt5/qtwebengine && git submodule update --init **# updating qtwebengine module to get 3rdparty's chromium**  
$ cd qt5  
$ ./configure -prefix $WRSCOMPOSITOR -nomake examples -gstreamer -nomake tests -confirm-license -opensource -kms -opengl es2 -egl -linuxfb  
$ make && make install **# building all of qt-modules**  
$ cd qt5/qtwayland  
$ qmake CONFIG+=wayland-compositor **# building qtwayland to build/run wrscompositor**  
$ make && make install

Configuration/Installation for WRSCompositor

After install Qt Library, You can configure/build/install wrscompositor based on qtwayland.

  1. Configure wrscompositor that is able to work on Linux Desktop.
    if you want to know more available options in configure, Try to use --help option.
$ ./configure --with-qmake=$WRSCompositor/bin/qmake --hmi-profile=cockpit --overwrite

$ export QT_QPA_PLATFORM=eglfs **# WRSCompositor is main-compositor that is able to access gpu driver.**  
$ export XDG_RUNTIME_DIR="/run/user/1000" **# Try to check specific number related to login account (ex: general user account is mapped to 1000)**    
$ wrscompositor &  **# Try to use --help option to know more avaiable arguments.**

When wrscompositor want to be sub-compositor under main-compositor like weston, you need to export QT_QPA_PLATFORM to wayland.

After run WRSCompositor as background process, You can run such a applications based on QT or non-QT under WRSCompositor.

  1. Non QT application like weston client.
    this applcation should include wayland client-protocol to commuicate with WrsCompositor.

    if wayland-0 is created in this directory, wrscompositor can composite client's window.
