0.准备工作
将所有源代码包都复制到 /home/lean/6410目录中
终端切换到root权限：#sudo su
1.交叉编译工具安装
将arm-linux-4.4.1.tar.gz解压缩到/usr/local/arm目录中
解压缩：#tar zvxf arm-linux-4.4.1.tar.gz -C /usr/local/arm
设置环境变量：#export PATH=/usr/local/arm/4.4.1/bin:$PATH
一、编译和安装依赖包
2.tslib 编译与安装
这里直接采用飞凌编译好的tslib，所以暂无需要编译和安装。如果需要自行编译可参考《OK6410 QT移植百科全书.pdf》
直接拷贝飞凌的/usr/local/tslib到uBuntu的/usr/local目录中
设置环境变量：
#export TSLIB=/usr/local/tslib
#export TSLIB_CFLAGS=$TSLIB/lib
#export TSLIB_LIBS=$TSLIB/lib
3.zlib编译与安装
解压缩: #tar zvxf zlib-1.2.5.1.tar.gz
配置：
#CC=arm-none-linux-gnueabi-gcc ./configure --prefix=/usr/local/zlib
编译及安装：
#make
#make install
设置环境变量：
#export ZLIB=/usr/local/zlib
4.libjpeg编译与安装
解压缩: #tar zvxf jpegsrc.v8d.tar.gz
切换目录：#cd jpeg-8d
执行配置：#./configure --host=arm-linux --prefix=/usr/local/libjpeg --enable-shared
执行编译：#make
执行安装：#make install
设置环境变量：
#export LIBJPEG=/usr/local/libjpeg
4.libpng编译与安装
解压缩：#tar zvxf libpng-1.5.8.tar.gz
切换目录：#cd libpng-1.5.8
配置：#./configure --host=arm-linux --prefix=/usr/local/libpng
编译及安装：
#make
#make install
设置环境变量：
#export LIBPNG=/usr/local/libpng
#export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/libpng/lib/pkgconfig
注意：由于libpng-1.5.8在安装的时候漏拷贝了其根目录下的pnginfo.h和pngstruct.h到安装目录，所以这里要手动
拷贝这两个文件到/usr/local/libpng/include/libpng15目录中，否则在编译directFB时候会出错。
5.freetype编译与安装
解压缩：#tar zvxf freetype-2.4.8.tar.gz
切换目录：#cd freetype-2.4.8
配置：#./configure --host=arm-linux --prefix=/usr/local/freetype
编译及安装：
#make
#make install
设置环境变量：
#export FREETYPE=/usr/local/freetype
#export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/freetype/lib/pkgconfig
至此directFB所需的依赖包都安装完成。注意：在安装libpng前首先得安装zlib否则会出现找不到zlib错误出现。
二、编译和安装directFB
1.设置环境变量
#export LDFLAGS="$LDFLAGS -L$TSLIB/lib -L$LIBJPEG/lib -L$LIBPNG/lib -L$FREETYPE/lib -L$ZLIB/lib -lm"
#export CFLAGS="$CFLAGS -I$TSLIB/include -I$LIBJPEG/include -I$LIBPNG/include -I$FREETYPE/include -I$ZLIB/include"
2.对directFB-1.4.9应用补丁
directFB-1.4.9使用libpng-1.5.x会出现版本不兼容的情况，所以需要对directFB-1.4.9源码打libpng-1.5.x支持补丁。
解压源代码：#tar zvxf DirectFB-1.4.9.tar.gz
切换目录：#cd DirectFB-1.4.9
应用补丁：#patch -p1 < ../DirectFB-1.4.9-libpng-1.5.patch
如果出现patch命令不存在要先安装patch：apt-get install patch
补丁成功以后将会提示应用补丁的文件列表。
3.配置directFB
#./configure --host=arm-linux --prefix=/usr/local/directFB --with-gfxdrivers=none --with-inputdrivers=all --enable-png --enable-jpeg --disable-tiff --enable-zlib --enable-sdl=no --enable-gif=no --disable-x11 --enable-debug --sysconfdir=/etc --enable-fbdev
等待配置完成，并查看所对应的模块是否已经找到，如果出现未找到某个模块，要着重检查环境变量是否设置正确，尤其是下面两个。
#export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/freetype/lib/pkgconfig
#export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/libpng/lib/pkgconfig
4.编译及安装
#make
#make install
三、开发板部署
1.cramfs文件系统制作
将uBuntu /usr/local/目录下的 tslib, libjpeg, libpng, freetype, zlib, directFB 文件夹拷贝到开发板cramfs镜像的/usr/local目录中。
修改cramfs镜像中/usr/local文件权限(不修改貌似也可以)
#chmod 777 -R /usr/local/
修改镜像/etc/init.d/rcS文件，添加如下环境变量：
#export TSLIB=/usr/local/tslib
#export LIBJPEG=/usr/local/libjpeg
#export LIBPNG=/usr/local/libpng
#export FREETYPE=/usr/local/freetype
#export ZLIB=/usr/local/zlib
#export DIRECTFB=/usr/local/directFB
#export TSLIB_CONSOLEDEVICE=none
#export TSLIB_FBDEVICE=/dev/fb0
#export TSLIB_TSDEVICE=/dev/input/event1
#export TSLIB_PLUGINDIR=$TSLIB/lib/ts
#export TSLIB_CONFFILE=$TSLIB/etc/ts.conf
#export TSLIB_CALIBFILE=/etc/pointercal
#export LD_LIBRARY_PATH=$TSLIB/lib:$LIBJPEG/lib:$LIBPNG/lib:$FREETYPE/lib:$ZLIB/lib:$DIRECTFB/lib
修改或新建/etc/directfbrc文件，内容如下：
system=fbdev
fbdev=/dev/fb0
wm=default
重新打包cramfs文件镜像，利用USB或一键烧写到开发板。
重启开发板：
