h3. Compiling Qt 4.8.0
Set the development environment variables using following commands
<br /> cd /path/to/STM_SDK_3.5/<br /> source /path/to/STM_SDK_3.5/mysetenv.sh HDK7108_7108_LINUX<br />
Configure, build and install Qt 4.8.0 as
<br /> $ /path/to/qt-everywhere-opensource-src-4.8.0/configure -opensource -confirm-license -verbose -release -shared -no-rpath -system-zlib -system-libjpeg -system-libpng -qt3support -qt-sql-sqlite -xmlpatterns -exceptions -declarative -script -scripttools -webkit -no-javascript-jit -qt-gfx-linuxfb -qt-gfx-transformed -qt-gfx-vnc -qt-gfx-multiscreen -qt-kbd-linuxinput -qt-mouse-linuxinput -make libs -make tools -make examples -make demos -make docs -make translations -platform qws/linux-x86-g''+ —prefix=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/ -xplatform qws/linux-sh4-ST7108-g++ -embedded sh4 -little-endian -opengl es2 -plugin-gfx-eglnullws -qt-gfx-directfb <s>no-dbus<br /> $ make<br /> $ make install<br />
After the build succeeds set following environment variables before building any Qt Apps,
# QTDIR=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/
# PATH=/path/to/installation/directory/qt-everywhere-opensource-src-4.8.0-qws/bin/
h2. Qt 5.0 EGLFS/QPA
Only QtBase module is tested.
h3. Compiling Qt 5.0
One need to pass following "device-option"s
# CROSS_COMPILE=<STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/bin/sh4-linux
Configure, build and install Qt 5.0 as
<br /> $ configure —prefix=/path/to/installation/directory/qt-gitorious-opensource-src-5.0 -release -opensource -confirm-license -shared -verbose -device linux-sh4-stmicro-ST7108-g++ -sysroot <STLinux-2.4 installation path&gt;/STLinux-2.4/devkit/sh4/target <s>device-option CROSS_COMPILE=<STLinux-2.4 installation path&gt;/STLinux-2.4/devkit/sh4/bin/sh4-linux</s><br /> $ make module-qtbase<br /> $ make module-qtbase-install_subtargets<br />
After the build succeeds set following environment variables before building any Qt Apps,
# QTDIR=/path/to/installation/directory/qt-gitorious-opensource-src-5.0/
# 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
