Qt 5.3.2在周立功M3352开发板的移植记录

1.一般板子上都带有配套的交叉编译，没有的话，可以从网上下一个。交叉编译器的放在/opt/tools/arm-2011.03/bin

看一下应该是这样的 

2.到www.qt-project.org下载QT5.3.2的源代码qt-everywhere-opensource-src-5.3.2.tar.gz。

3.解压到当前文件夹。tar xzvf qt-everywhere-opensource-src-5.3.2.tar.gz.  我的源码放在/opt/qt下。

4.在arm板上移植，需要知道芯片的架构。我的是ARM Cortex-A8,其架构是armv7-a。我们进入/opt/qt/qt-everywhere-opensource-src-5.3.1/qtbase/mkspecs/linux-arm-gnueabi-g++目录下，需要修改qmake.conf文件。如下

#
# qmake configuration for building with arm-linux-gnueabi-g++
#

MAKEFILE_GENERATOR      = UNIX
CONFIG                 += incremental
QMAKE_INCREMENTAL_STYLE = sublib

QMAKE_CFLAGS_RELEASE   += -O2 -march=armv7-a
QMAKE_CXXFLAGS_RELEASE += -O2 -march=armv7-a

include(../common/linux.conf)
include(../common/gcc-base-unix.conf)
include(../common/g++-unix.conf)

# modifications to g++.conf
QMAKE_CC                = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-gcc      #交叉编译器的绝对路径
QMAKE_CXX               = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-g++
QMAKE_LINK              = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-g++
QMAKE_LINK_SHLIB        = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-g++

# modifications to linux.conf
QMAKE_AR                = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-ar cqs
QMAKE_OBJCOPY           = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-objcopy
QMAKE_NM                = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-nm -P
QMAKE_STRIP             = /opt/tools/arm-2011.03/bin/arm-none-linux-gnueabi-strip

load(qt_config)

5.进入/opt/qt/qt-everywhere-opensource-src-5.3.1/，编译脚本

sudo mkdir arm_config

sudo chmod 777 arm_config

sudo vi arm_config

./configure -v \
        -prefix /usr/local/qt-everywhere-opensource-src-5.3.2 \     交叉编译之后的目录
        -confirm-license \
        -opensource \
        -release  \
        -make libs \
        -xplatform linux-arm-gnueabi-g++ \      
        -optimized-qmake \
        -pch \
        -qt-sql-sqlite \
        -qt-libjpeg \
        -qt-zlib \
        -no-opengl \
        -no-sse2 \
        -no-openssl \
        -no-nis \
        -no-cups \
        -no-glib \
        -no-xcursor -no-xfixes -no-xrandr -no-xrender \
        -no-separate-debug-info \

sudo make 

sudo make install 

等待几个小时之后完成。

6.进入/usr/local,把qt-everywhere-opensource-src-5.3.2拷到板子上/opt下

7.设置环境变量，打开/etc/profile

export TSLIB_ROOT=/usr
export QT_ROOT=/opt/qt-everywhere-opensource-src-5.3.2
export QWS_MOUSE_PROTO=tslib:/dev/touchscreen
export LD_LIBRARY_PATH=/lib:/usr/lib:/usr/local/lib:$QT_ROOT/lib:$LD_LIBARAY_PATH
export QT_QPA_PLATFORM_PLUGIN_PATH=$QT_ROOT/plugins
export QT_QPA_PLATFORM=linuxfb:tty=/dev/fb0
export QT_QPA_FONTDIR=$QT_ROOT/lib/fonts

重启 source /etc/profile.

8.运行demo的时候，中文汉字显示不了  进入/opt/qt-everywhere-opensource-src-5.3.2/lib/fonts下，删除所以字体，然后从网上下一个文泉驿字体库，我用的是wqy_mh.ttf，重新运行demo,字体就能正常显示了。
