Compiling Qt 4.8.0

Set the development environment variables using following commands

  1.  cd /path/to/STM_SDK_3.5/
  2.  source /path/to/STM_SDK_3.5/mysetenv.sh HDK7108_7108_LINUX
  3.  

Configure, build and install Qt 4.8.0 as
  1.  $ /path/to/qt-everywhere-opensource-src-4.8.0/configure -opensource -confirm-license \
  2.   -verbose -release -shared -no-rpath -system-zlib -system-libjpeg -system-libpng \
  3.   -qt3support -qt-sql-sqlite -xmlpatterns -exceptions -declarative -script -scripttools \
  4.   -webkit -no-javascript-jit -qt-gfx-linuxfb -qt-gfx-transformed -qt-gfx-vnc -qt-gfx-multiscreen \
  5.   -qt-kbd-linuxinput -qt-mouse-linuxinput -make libs -make tools -make examples -make demos \
  6.   -make docs -make translations -platform qws/linux-x86-g++ \
  7.   --prefix=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/ \
  8.   -xplatform qws/linux-sh4-ST7108-g++ -embedded sh4 -little-endian -opengl es2 \
  9.   -plugin-gfx-eglnullws -qt-gfx-directfb -no-dbus
  10.  $ make
  11.  $ make install
  12.  

After the build succeeds set following environment variables before building any Qt Apps,
  1. QTDIR=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/
  2. PATH=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/bin/

Qt 5.0 EGLFS/QPA

Only QtBase module is tested.

Compiling Qt 5.0

One need to pass following “device-option“s

  1. CROSS_COMPILE=<STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/bin/sh4-linux-

Configure, build and install Qt 5.0 as

  1.  $ configure --prefix=/path/to/installation/directory/qt-gitorious-opensource-src-5.0 -release -opensource -confirm-license -shared -verbose \
  2.  -device linux-sh4-stmicro-ST7108-g++ \
  3.  -sysroot <STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/target \
  4.  -device-option CROSS_COMPILE=<STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/bin/sh4-linux-
  5.  $ make module-qtbase
  6.  $ make module-qtbase-install_subtargets
  7.  

After the build succeeds set following environment variables before building any Qt Apps,
  1. QTDIR=/path/to/installation/directory/qt-gitorious-opensource-src-5.0/
  2. PATH=/path/to/installation/directory/qt-gitorious-opensource-src-5.0/bin/

Before executing any Qt applications on target copy “/path/to/installation/directory/qt-gitorious-opensource-src-5.0” from host on target at “/path/to/installation/directory/qt-gitorious-opensource-src-5.0” on target file system
