qt 5.3 cross compile 조사

... 맨날 조사만 하네..

Embedded Platforms You can develop with Qt for the following embedded platforms: Embedded Android Embedded Linux Windows Embedded (Compact and Standard) Real-Time Operating Systems, such as QNX, VxWorks and INTEGRITY [링크 : http://doc.qt.io/qt-5/supported-platforms.html]

./configure -release -opengl es2 -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$TOOLCHAIN/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf- -sysroot $ROOTFS -prefix /usr/local/qt5 LinuxFB This plugin writes directly to the framebuffer. Only software-rendered content is supported. Note that on some setups the display performance is expected to be limited. The linuxfb plugin allows specifying additional settings by passing them in the QT_QPA_PLATFORM environment variable or -platform command-line option. For example, QT_QPA_PLATFORM=linuxfb:fb=/dev/fb1 specifies that the framebuffer device /dev/fb1 should be used instead of the default fb0. Multiple settings can be specfified by separating them with a colon. Input When no windowing system is present, the mouse, keyboard and touch input are read directly via evdev or using helper libraries like tslib. Note that this requires that devices nodes /dev/input/event* are readable by the user. eglfs has all the evdev input handling code built-in, while linuxfb relies on the traditional and somewhat limited -plugin command-line parameters. Input on linuxfb To enable keyboard, mouse, touch or tablet support with linuxfb, pass QT_QPA_GENERIC_PLUGINS=evdevkeyboard,evdevmouse,evdevtouch,... in the environment or, alternatively, -plugin evdevkeyboard, -plugin evdevmouse, -plugin evdevtouch, or -plugin evdevtablet on the command-line. Most of these can take a device node parameter, for example QT_QPA_GENERIC_PLUGINS=evdevmouse:/dev/event1, in case the Qt's automatic device discovery (based either on libudev or a walkthrough of /dev/input/event*) is not functional or misbehaving.
