MiniGUI 1.6.10在SkyEye 1.3.1上的移植(基于tslib 1.4)

MiniGUI在SkyEye模拟的s3c2410上的移植还是比较容易的，注意下触摸屏的移植即可。这里用的tslib 1.4作为触摸屏的适配层，下面是具体步骤。

1. 下载libminigui-1.6.10.tar.gz(http://nchc.dl.sourceforge.net/project/minigui/minigui/GPL-V1.6.10/libminigui-1.6.10.tar.gz )、minigui-res-1.6.10.tar.gz(http://cdnetworks-kr-1.dl.sourceforge.net/project/minigui/minigui/GPL-V1.6.10/minigui-res-1.6.10.tar.gz )和mg-samples-1.6.10.tar.gz(http://nchc.dl.sourceforge.net/project/minigui/minigui/GPL-V1.6.10/mg-samples-1.6.10.tar.gz )

2. 安装tslib 1.4(http://blog.csdn.net/Matrix_Designer/archive/2010/12/10/6068629.aspx )

3. 执行下列脚本：
tar zxvf libminigui-1.6.10.tar.gz
cd libminigui-1.6.10/
rm config.cache config.status -f
CC=arm-linux-gcc ./configure --prefix=/opt/minigui1.6.10/ --build=i386-linux --host=arm-linux --target=arm-linux CFLAGS="-I/opt/tslib/include -L/opt/tslib/lib -lts"

4. gedit src/ial/dummy.c &
将其内容改成如下内容：

5. 执行下面脚本
make
make install
cd ..

tar zxvf minigui-res-1.6.10.tar.gz
tar zxvf mg-samples-1.6.10.tar.gz
mkdir test
cp ../mg-samples-1.6.10/src/animation.c ./
arm-linux-gcc -I/opt/minigui1.6.10/include -L/opt/minigui1.6.10/lib -O2 -o animation animation.c -lminigui -lmgext -lm -ljpeg -lpng -lpthread

成功编译MiniGUI。现在得到了MiniGUI的lib库和测试程序animation。需要将/opt/minigui1.6.10/lib下面的：
libminigui-1.6.so.10
libminigui-1.6.so.10.0.0
libmgext-1.6.so.10
libmgext-1.6.so.10.0.0
四个库文件拷贝到板子，和arm-linux-gcc的：
libjpeg.so.62
libjpeg.so.62.0.0
libpng.so.3
libpng.so.3.35.0
四个库文件，以及
/opt/minigui1.6.10/etc/MiniGUI.cfg需要拷贝到板子上的/etc/目录下。然后执行：
gedit MiniGUI.cfg &
将：
[system]
# GAL engine and default options
gal_engine=qvfb
defaultmode=800x600-16bpp

# IAL engine
ial_engine=qvfb
mdev=/dev/input/mice
mtype=IMPS2

[fbcon]
defaultmode=1024x768-16bpp
改成：
[system]
# GAL engine and default options
gal_engine=fbcon
defaultmode=640x480-16bpp

# IAL engine
ial_engine=dummy
mdev=/dev/ts
mtype=def

[fbcon]
defaultmode=640x480-16bpp

将所有的：
/usr/local/lib/minigui
替换成：
/opt/minigui1.6.10

最后，执行：
gedit etc/profile &
添加以下内容：
export MINIGUI_ROOT=/opt/minigui1.6.10
export PATH=$MINIGUI_ROOT/bin:$PATH
export LD_LIBRARY_PATH=$MINIGUI_ROOT/lib:$LD_LIBRARY_PATH

至此，搞定MiniGUI，可以在SkyEye中运行测试程序animation了。
