Software

1. STM SDK 3.5
2. STLinux-2.4 [stlinux.com]
3. sh4-linux crosstools from STM

Assumptions

1. STM reference software SDK 3.5 is built on Host PC as conveyed in STM’s documentation given by STM’s Field Application Engineer.
2. STM reference software SDK 3.5 is configured for “HDK7108_7108_LINUX”
3. Can run STM’s “Test-Tool” on reference board to test OenGL ES 2.0 and media playback.
4. The “sysroot” is located at “<STLinux-2.4 installation path>/STLinux-2.4/devkit/sh4/target”

5. Create folder named “linux-sh4-ST7108-g++” in “qt-everywhere-opensource-src-4.8.0/mkspecs/qws”
6. Get following files in “qt-everywhere-opensource-src-4.8.0/mkspecs/qws/linux-sh4-ST7108-g++”
   1. https://gitorious.org/qt-platform-mkspecs/qt-platform-mkspecs/blobs/master/4.8/qws/linux-sh4-ST7108-g++/qmake.conf
   2. https://gitorious.org/qt-platform-mkspecs/qt-platform-mkspecs/blobs/master/4.8/qws/linux-sh4-ST7108-g++/qplatformdefs.h

Compiling Qt 4.8.0

Set the development environment variables using following commands Configure, build and install Qt 4.8.0 as 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 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
