1、移植dbus：
./configure --host=arm-linux --prefix=/usr/local/arm/ CC=arm-linux-gcc --cache-file=arm-linux.cache --without-x CFLAGS=-I/usr/local/arm/include LDFLAGS=-L/usr/local/arm/lib
报错：checking abstract socket namespace... configure: error: cannot run test program while cross compiling
解决：1，首先用locate pkgconfig查看下pkgconfig安装了没有，一般都安装了。找到路径配置到环境变量里：export PKG_CONFIG_PATH=/usr/lib/pkgconfig
2，光设这个环境变量还是不行的，在终端里输入：
#echo ac_cv_have_abstract_sockets=yes>arm-linux.cache
之后，./configure通过！
make
make install
2、移植alsa
./configure --target=arm-linux --host=arm --prefix=/usr/local/arm/
make
make install
3、移植 pcre-8.39.tar.bz2 给qt编译的参数-system-pcre 使用；
./configure --host=arm --target=arm-linux --prefix=/usr/local/arm --enable-pcre16
make
make install
4、移植QT5.6
echo yes | ./configure --prefix=/usr/local/Trolltech/QtEmbedded-5.6.0-arm -opensource -debug -no-c++11 -xplatform linux-arm -alsa -opengl es2 -eglfs -qt-freetype -system-pcre -nomake tests -make examples -v -I/usr/local/arm/include -L/usr/local/arm/lib -I/usr/local/arm/nexell/include/khronos -L/usr/local/arm/nexell/lib
make
make install
a、
eglconvenience/qeglstreamconvenience_p.h:56:9: error: ‘intptr_t’ does not name a type
typedef intptr_t EGLAttrib;
^
In file included from eglconvenience/qeglstreamconvenience.cpp:34:0:
增加 typedef int intptr_t ；
b、
vim qtbase/src/plugins/platforms/eglfs/deviceintegration/eglfs_mali/qeglfsmaliintegration.cpp
注释掉 fbdev_window 结构体定义
5、附件文件说明（文件下载地址 ：

linux-arm.tar.bz2
qt的编译配置文件，解压到QT源码的qtbase/mkspecs/目录下，主要修改qmake.conf文件
#
# qmake configuration for building with arm-linux-gnueabi-g++
#
MAKEFILE_GENERATOR = UNIX
CONFIG += incremental
QMAKE_INCREMENTAL_STYLE = sublib
QT_QPA_DEFAULT_PLATFORM = linuxfb
QMAKE_CFLAGS_RELEASE += -O2 -march=armv7-a
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a

QMAKE_LIBDIR_OPENGL_ES2 = /usr/local/arm/nexell/lib
QMAKE_INCDIR_EGL = /usr/local/arm/nexell/include/khronos/
QMAKE_LIBDIR_EGL = /usr/local/arm/nexell/lib

QMAKE_AR = arm-linux-ar cqs
QMAKE_OBJCOPY = arm-linux-objcopy
QMAKE_NM = arm-linux-nm -P
QMAKE_STRIP = arm-linux-strip
load(qt_config)
b、nexell.tar.bz2
这是三星官方提供的OpenGL的库和头文件
解压到 /usr/local/arm 下面。如果需的话把这个包也解压到开发板中。
c、QtEmbedded-5.6.0-arm.tar.bz2
编译完成的安装包，可以解压到开发板中运行测试程序
比如：进入QtEmbedded-5.6.0-arm/examples/qt3d/lights
# ./lights -platform eglfs
可以在屏幕上看到3D灯照的效果。
