原来虽然移植过qt，但这次用友善之臂的tiny6410移植QT4.7.3还是费了一下午时间。

现在写点什么总结下。

【目标板】tiny6410

【编译器】arm-linux-gcc 4.3.2

【安装源】

(1) Qt_SDK_Lin32_offline_v1_1_2_en.run

http://qt.nokia.com/downloads/sdk-linux-x11-32bit-cpp-offline

(2) qt-everywhere-opensource-src-4.7.3.tar.gz

http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.7.3.tar.gz

(3) tslib1.4.tar.gz

(4) arm-linux-gcc 4.3.2

步骤：

（1）将qt-everywhere-opensource-src-4.7.3.tar.gz解压到指定目录

（2）终端cd进入qt-everywhere-opensource-src-4.7.3.tar.gz解压目录

（3）配置

# ./configure -prefix /opt/QtEmbedded-4.7.3 -release -shared -fast -pch -no-qt3support -qt-sql-sqlite -no-libtiff -no-libmng -qt-libjpeg -qt-zlib -qt-libpng -qt-freetype -no-openssl -nomake examples -nomake demos -nomake tools -optimized-qmake -no-phonon -no-nis -no-opengl -no-cups -no-xcursor -no-xfixes -no-xrandr -no-xrender -no-xkb -no-sm -no-xinerama -no-xshape -no-separate-debug-info -xplatform qws/linux-arm-g++ -embedded arm -depths 16 -no-qvfb -qt-gfx-linuxfb -no-gfx-qvfb -no-kbd-qvfb -no-mouse-qvfb -confirm-license -qt-mouse-tslib -I/opt/tslib/include -L/opt/tslib/lib

备注：

最后3句是指定使用触摸屏，并制定tslib1.4的安装目录的头文件以及库函数。我的tslib是安装在opt下。

（4）make

（5）make install

至此arm版的qt4.7.3安装完毕，在arm板上跑qt的支持文件为/opt/QtEmbedded-4.7.3，将整个文件夹拷贝到arm板的文件系统的相应位置下即可。

注意：

开始我用的友善自带的工具链4.5.1，用上面的配置出现错：

shared/qimage_neon.o image/qimage_neon.cpp
image/qimage_neon.cpp: In function 'void qt_convert_rgb888_to_rgb32_neon(quint32*, const uchar*, int)':
image/qimage_neon.cpp:66: error: 'uint8x8_t' does not name a type
image/qimage_neon.cpp:82: error: 'fullVector' was not declared in this scope
make[1]: *** [.obj/release-shared/qimage_neon.o] Error 1
make[1]: Leaving directory `/home/hancy/qt_src/qt-everywhere-opensource-src-4.7.4/src/gui'
make: *** [sub-gui-make_default-ordered] Error 2

hmmm, you need add arm_neon.h to your qt sorce code, and modify the image/qimage_neon.cpp add #include "yourpath/arm_neon.h" under #ifdef QT_HAVE_NEON
you can find arm_neon.h from attached.

把arm_neon.h头文件也加入，接着出现错误：

shared/qimage_neon.o image/qimage_neon.cpp
In file included from image/qimage_neon.cpp:45:
image/arm_neon.h:32:2: error: #error You must enable NEON instructions (e.g. -mfloat-abi=softfp -mfpu=neon) to use arm_neon.h
