開發平臺：omap4430
pc主機：ubuntu10.04
交叉編譯器：arm-2010q1-202-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.gz

echo "<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make start>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n"

設定交叉編譯器的環境變數

gedit .bashrc

export PATH=$PATH:/usr/local/arm/arm-2010q1/bin
(1)編譯tslib
tar -xvf tslib-1.0.tar.gz
cd tslib-1.0/
make clean
./autogen.sh
./configure --prefix=/home/nation/tslib-arm --host=arm-none-linux-gnueabi ac_cv_func_malloc_0_nonnull=yes

make
make install
export TSLIB=/home/nation/tslib-arm
echo "\n<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make tslib-1.0 end>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n\n\n"
cd ../
(2)編譯zlib(注：應該先編譯，因為libpng編譯時用到該庫)
tar xvf zlib-1.2.5.tar.bz2
cd zlib-1.2.5/
make clean
export CC=arm-none-linux-gnueabi-gcc(//zlib的arm編譯需要如此宣告，而不是單純的./configuer --host=arm-linux)
./configure -shared --prefix=/home/nation/zlib-arm
make
make install
export ZLIB=/home/nation/zlib-arm/
echo "\n<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make zlib-1.2.5 end>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n\n\n"
cd ../
(3)編譯jpeg庫
tar xvf jpegsrc.v6b.tar.gz
cd jpeg-6b/
make clean
./configure --host=arm-none-linux-gnueabi --prefix=/home/nation/libjpeg-arm --enable-shared
make
make install
export LIBJPEG=/home/nation/libjpeg-arm/
echo "\n<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make  jpeg-8c end>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n\n\n"
cd ../
(4)編譯libpng
tar xvf libpng-1.2.44.tar.gz
cd libpng-1.2.44/
make clean
export ZLIB=/home/nation/zlib-arm/
export LDFLAGS="-L$ZLIB/lib"
export CPPFLAGS="-I$ZLIB/include"
./configure --host=arm-none-linux-gnueabi --prefix=/home/nation/libpng-arm    ac_cv_func_malloc_0_nonnull=yes
make
make install
export LIBPNG=/home/nation/libpng-arm/
echo "\n<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make libpng-1.2.46 end>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n\n\n"
cd ../

這裡加上了ac_cv_func_malloc_0_nonnull=yes用來去掉config.h中的rp_malloc，防止在編譯dfb的時候報錯。

(5) 編譯freetype-2.4.4
tar xvf freetype-2.4.4.tar.gz
cd freetype-2.4.4/
make clean
./configure --host=arm-none-linux-gnueabi --prefix=/home/nation/freetype-arm 
make
make install
export FREETYPE=/home/nation/freetype-arm
echo "\n<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make freetype-2.4.2 end>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n\n\n"
cd ../
unset LDFLAGS
unset CFLAGS
export LDFLAGS="$LDFLAGS -L$TSLIB/lib -L$LIBJPEG/lib -L$LIBPNG/lib -L$FREETYPE/lib -L$ZLIB/lib"
export CFLAGS="$CFLAGS -I$TSLIB/iclude -I$LIBJPEG/include -I$LIBPNG/include -I$FREETYPE/include -I$ZLIB/include"
(6)編譯DirectFB-1.4.5
tar xvf DirectFB-1.4.5.tar.gz
cd DirectFB-1.4.5
make clean
./configure --host=arm-none-linux-gnueabi --target=arm-none-linux-gnueabi --prefix=/home/nation/directFB-arm --with-gfxdrivers=none --with-inputdrivers=all --enable-png --enable-jpeg --enable-zlib --enable-sdl=no --enable-gif=no --enable-debug --sysconfdir=/etc --enable-fbdev --disable-x11

make
make install

export DIRECTFB=/home/nation/directFB-arm
echo "\n<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make DirectFB-1.4.5 end>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n\n\n"
cd ../

注意：可能會有出錯提示

/opt/gcc-3.4.6/bin/../lib/gcc/mipsel-linux/3.4.6/../../../../mipsel-linux/b in/ld: warning:  libz.so.1,  needed by /usr/directfb/lib/libpng12.so, not  found (try using -rpath or  -rpath-link)

collect2: ld returned 1 exit status

make[2]: *** [directfb-csource] 錯誤 1

make[2]:正在離開目錄 `/******/DirectFB-1.3.0/tools'

參考解決辦法：

$cp /usr/directfb-gtk/lib/lib* /opt/gcc-3.4.6/mipsel-linux/lib/

——主要是用第五步的libpng-1.2.40所編譯出來的庫檔案

來更新交叉編譯工具鏈的動態庫檔案libpng12.so

(7)編譯DirectFB-examples-1.2.0
unset LDFLAGS
unset CFLAGS

export LDFLAGS="$LDFLAGS -L$TSLIB/lib -L$LIBJPEG/lib -L$LIBPNG/lib -L$FREETYPE/lib -L$ZLIB/lib -L$DIRECTFB/lib"
export CFLAGS="$CFLAGS -I$TSLIB/iclude -I$LIBJPEG/include -I$LIBJPEG/include -I$FREETYPE/include -I$ZLIB/include -L$DIRECTFB/include"

tar xvf DirectFB-examples-1.2.0.tar
cd DirectFB-examples-1.2.0
./configure --host=arm-none-linux-gnueabi --prefix=/home/nation/directFB-example-arm
make
make install
echo "<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<make all are end>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>\n"

(8)建立/etc/directfbrc
system=fbdev
fbdev=/dev/fd0
wm=default
mode=640x480
depth=32
pixelformat=RGB32
(9)啟動引數：
export TSLIB=/home/nation/tslib-arm/
export LIBJPEG=/home/nation/libjpeg-arm/
export LIBPNG=/home/nation/libpng-arm/
export ZLIB=/home/nation/zlib-arm/
export FREETYPE=/home/nation/freetype-arm
export DIRECTFB=/home/nation/directFB-arm/
export TSLIB_CONSOLEDEVICE=none
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_TSDEVICE=/dev/input/event1
export TSLIB_PLUGINDIR=$T_ROOT/lib/ts
export TSLIB_CONFFILE=$T_ROOT/etc/ts.conf
export TSLIB_CALIBFILE=/etc/pointercal
export LD_LIBRARY_PATH=$TSLIB/lib:$LIBJPEG/lib:$LIBPNG/lib:$FREETYPE/lib:$ZLIB/lib:$DIRECTFB/lib

以下為本人在移植過程中遇到的錯誤及其解決方法：

(1)libpng在configuer時的錯誤
./configure --host=arm-none-linux-gnueabi --prefix=/home/nation/libpng-arm
後產生以下錯誤：
configure: error: zlib not installed
解決方法：
export ZLIB=/home/nation/zlib-arm/
export LDFLAGS="-L$ZLIB/lib"
export CPPFLAGS="-I$ZLIB/include"

()2DirectFB1.3.0編譯過程的錯誤及解決

./configure --host=arm-linux --prefix=/home/nation/directFB-arm --with-gfxdrivers=none --with-
inputdrivers=all --enable-png --enable-jpeg --enable-zlib --enable-sdl=no --enable-gif=no --enable-debug
--sysconfdir=/etc --enable-fbdev  後出錯如下所示：

hecking for C compiler default output file name...
configure: error: C compiler cannot create executables
See `config.log' for more details.

解決方法：ubuntu系統中安裝支援包
sudo apt-get install gcc libc6-dev

(3)出現找不到png.h時的解決方法:
將gedit interfaces/IDirectFBImageProvider/idirectfbimageprovider_png.c 中的include "png.h"改為libpng編譯
安裝後的路徑如本人的是include "/home/nation/libpng-arm/include/png.h"

(4)編譯directFB或DirectFB-examples-1.2.0時有以下類似的錯誤
../src/.libs/libdirectfb.so: undefined reference to `gzdopen'
../src/.libs/libdirectfb.so: undefined reference to `gzclose'
../src/.libs/libdirectfb.so: undefined reference to `gzwrite'
collect2: ld returned 1 exit status
make[2]: *** [dfbdump] Error 1
make[2]: Leaving directory `/home/dorke/work/DirectFB-1.2.9/tools'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/dorke/work/DirectFB-1.2.9'
make: *** [all] Error 2
 
類似的錯誤用類似的解決辦法： 加上-lm -lz
vi tools/Makefile
LDFLAGS =  -L/forlinx/build/tslib/lib -L/forlinx/build/libjpeg/lib -L/forlinx/build/libpng/lib -
L/forlinx/build/freetype/lib -L/forlinx/build/zlib/lib -lm -lz

DirectFB-examples-1.2.0中./configuer時
configure: error: No package 'directfb' found

原來在移植軟體包的時候，在所要用的軟體包，在每個（？？）的lib/pkgconfig目錄下都有個*.pc檔案，

在./configure就是靠這個檔案進行配置的，比如：DIRECTFB/LIB/PKGCONFIG/directfb.pc，我./configure出錯的原因

就是沒有找到這個檔案，所以說DIRECTFB沒有這個包。解決辦法是設定PKG_CONFIG_PATH變數，

 
checking for DIRECTFB... no
configure: error: No package 'directfb' found
*** DirectFB 1.2.0 or newer is required. The latest version
*** of DirectFB is available from http://www.directfb.org/.
解決方法
export PKG_CONFIG_PATH=/home/nation/directFB-arm/lib/pkgconfig

DirectFB執行例子是出錯：

./df_andi

 (#) DirectFBError [dfb->CreateFont( dfb, FONT, &desc, &font )]: No (suit
able) implementation found!
