QT4.8 Porting on ARM6410L/編譯環境 Ubuntu 10.04LTS Kernel 2.6.32-38-generic

-----------------前置工作安裝Cross Tool Chain -----------------

sudo apt-get install autoconf automake libtool
wget https://www.dropbox.com/s/viw8gg5n896kfu3/4.3.1-eabi-armv6-20080707.tar.bz2
sudo mkdir -p /usr/local/arm
sudo chmod 1777 /usr/local/arm
sudo chown -R $USER:$GROUPS /usr
cd /usr/local/arm
tar jxvf ~/Download/4.3.1-eabi-armv6-20080707.tar.bz2
vi .bashrc在底下新增兩行
CCACHE_PATH=/usr/local/arm/4.3.1-eabi-armv6/usr/bin:$CCACHE_PATH
PATH=/usr/local/arm/4.3.1-eabi-armv6/usr/bin:$PATH
重新啟動Terminal 或者source .bashrc

-----編譯需要的函式庫：zlib、tslib、libmad、libid3tag、madplay-----

wget http://www.csie.nctu.edu.tw/~yenming/lab.tar.gz

tar xvf lab.tar.gz
//移植zlib
tar xvf zlib-1.2.5.tar.gz
cd  zlib-1.2.5/
./configure --prefix=/opt/arm/usr --shared
vi Makefile
修改
AR=arm-linux-ar rc
RANLIB=arm-linux-ranlib
make
make install
//移植tslib
wget https://www.dropbox.com/s/0zi00hu2nri9nxa/tslib1.4.tar.gz.gz
tar xvf tslib1.4.tar.gz
cd tslib
./autogen.sh
./configure --prefix=/opt/arm/usr CC=arm-linux-gcc --host=arm-linux ac_cv_func_malloc_0_nonnull=yes
make
make install
vi /opt/arm/usr/etc/ts.conf

將第二行

＃module_raw input

改成module_raw input  （注意前方不要留空格）

module variance delta=300  //濾波參數
module dejitter delta=500    //降噪參數

//移植libmad

tar xvf libmad-0.15.1b.tar.gz

cd  libmad-0.15.1b

./configure --host=arm-linux --prefix=/opt/arm/usr --disable-shared --disable-debugging

vi Makefile

刪除--fforce-mem字串

make

make install

//移植libid3tag
sudo apt-get source libid3tag

sudo chown -R  $USER:$GROUPS libid3tag-0.15.1b

./configure CC=/usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-gcc --prefix=/opt/arm/usr --host=arm-linux --disable-debugging --disable-shared --enable-static CPPFLAGS=-I/opt/arm/usr/include LDFLAGS=-L/opt/arm/usr/lib

make

make install

//移植madplay

sudo apt-get source madplay

sudo chown -R $USER:$GROUPS madplay-0.15.2b

./configure CC=/usr/local/arm/4.3.1-eabi-armv6/usr/bin/arm-linux-gcc --prefix=/opt/arm/usr --host=arm-linux --disable-debugging --disable-shared --enable-static CPPFLAGS=-I/opt/arm/usr/include LDFLAGS=-L/opt/arm/usr/lib

make

make install

---------------------進入正題，開始移植Qt4.8---------------------

wget http://releases.qt-project.org/qt4/source/qt-everywhere-opensource-src-4.8.2.tar.gz

tar xvf  qt-everywhere-opensource-src-4.8.2.tar.gz

cd qt-everywhere-opensource-src-4.8.2

export QTDIR=$PWD

export PATH=$QTDIR:$PATH

export LD_LIBRARY_PATH=$QTDIR/lib:/opt/arm/usr/lib:$LD_LIBRARY_PATH

vi $QTDIR/mkspecs/qws/linux-arm-g++/qmake.conf

QMAKE_CC = arm-linux-gcc

QMAKE_CXX = arm-linux-g++

QMAKE_LINK = arm-linux-g++

QMAKE_LINK_SHLIB = arm-linux-g++

QMAKE_AR = arm-linux-ar cqs

QMAKE_OBJCOPY = arm-linux-objcopy

QMAKE_STRIP = arm-linux-strip

mkdir -p /opt/arm/usr

./configure --prefix=/opt/arm/usr -xplatform qws/linux-arm-g++ -little-endian -no-qvfb -embedded arm -qt-zlib -qt-libpng -qt-libtiff -qt-libmng -qt-libjpeg  -no-webkit -no-freetype -no-openssl -qt-mouse-tslib -L/opt/arm/usr/lib -I/opt/arm/usr/include

將編好的程式移植到目標版上
mkdir -p ~/rootfs/opt/arm/usr

cp -a /opt/arm/usr ~/rootfs/opt/arm/usr

vi ~/rootfs/etc/profile
---新增以下內容---

export TSLIB_ROOT=/opt/arm/usr
export TSLIB_TSDEVICE=/dev/event1
export TSLIB_CALIBFILE=$TSLIB_ROOT/etc/pointercal
export TSLIB_CONFFILE=$TSLIB_ROOT/etc/ts.conf
export TSLIB_PLUGINDIR=$TSLIB_ROOT/lib/ts
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export QTDIR=/opt/arm/usr
export QWS_MOUSE_PROTO="tslib"
export QWS_DISPLAY=LinuxFb:mmWidth=100:mmHeight=100
export QWS_SIZE="480x272"
export PATH="/opt/arm/usr/bin:$PATH"
export LD_LIBRARY_PATH="/opt/arm/usr/lib:$LD_LIBRARY_PATH"
export PKG_CONFIG_PATH="/opt/arm/usr/lib/pkgconfig"

如果你是用燒錄影像檔的方式到目標板上的話
在此特別注意影像檔案大小
是否超過編譯Kernel時所設定的rootfs容量大小
相關設定在kernel源碼資料夾下的
arch/arm/plat- s3c/include/plat/partition.h
如果有超過卻有沒修改的話會有以下幾個錯誤特徵：
無法正常開機
遺失一些lib
某些指令無法正常執行
所以~還是儘快重編kernel調整磁區大小吧!
另外簡單介紹一下partition.h 設定參數
offset表示開始位置size表示容量大小
像右圖就是設定
.name="U-boot",
.offset = 0,
.size    = (4*SZ_1M),
.name="Kernel",
.offset  (1*SZ_1M),
.size (1*SZ_3M),
0x8000000換算為10進位剛好是本塊nand flash大小128Mb

/****在目標版上測試tslib能否使用****/

在目標版執行tslib1.4校正TouchPanel
ts_calibrate
校正Touch Panel邊界,跟著它出現的畫面做操作
ln -s /opt/arm/usr/etc/pointercal /etc/pointercal
建置連結tslib執行時會參照的檔案
ts_test
測試Touch Panel是否正常

/****在目標版上測試QT及其觸控供能否使用****/
