QT5.2，UBUNTU，在arm-linux-gcc 4.4.1（EABI）下编译。
TSLIB为1.4，目标板CPU为S3C2440
编译过程：
修改qtbase/mkspecs/linux-arm-gnueabi-g++下的
qmake.conf 里的路径, 并添加:
QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv4t
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv4t
之后./configure -xplatform linux-arm-gnueabi-g++ -release -opensource -confirm-license -make libs --prefix $PWD/_install -no-c++11
用生成的QMAKE在qtbase/src/plugins/genric/tls里面，qmake -o Makefile tslib.pro，make && make install
编译结果运行QT应用时，提示：
QTsLibMouseHandler "tslib" "/dev/input/event0"
Couldnt load module pthres
Error configuring
: No such file or directory
触屏不能用，鼠标不能用。
提示This plugin does not support propagateSizeHints()，窗口无标题栏。
求救~~~~~
