skyeye install
(一)skyeye install:
sudo apt-get install libxft-dev libx11-dev libxpm-dev
sudo apt-get install libncurses5-dev
./configure
make lib
make
sudo make install_lib
sudo make install
(二)dowload arm-linux-gcc
需要注意的是gcc最好使用友善之臂的4.4.3(http://arm9download.cncncn.com/mini2440/linux/arm-linux-gcc-4.4.3-20100728.tar.gz )，传说中这个版本编译QT时能避免所有的Segmentation Fault
#tar -jxvf arm-linux-gcc-4.4.3-20100728.tar.gz
# cd .........
#cp -rv .... /usr/local/
现在交叉编译程序集都在........../4.4.3/bin下面了
vi /etc/bash.bashrc
export PATH=$PATH:/usr/local/arm/4.4.3/bin
export PATH
更新
source bash.bashrc
(三)compile linux kernel supporting LCD, touchmonitor
先下载linux-2.6.36.tar.bz2(ftp://ftp.kernel.org/pub/linux/kernel/v2.6/linux-2.6.36.tar.bz2 sudo tar jxvf linux-2.6.36.tar.bz2
使用tar命令时为什么会有“不允许的操作":权限不够，你用root操作应该就不会了。另外在解包时放在linux分区上，不要在win分区下。
win分区不支持符号链接。
tar jxvf linux-2.6.36.tar.bz2
2. cd linux-2.6.36/
3. gedit arch/arm/mach-s3c2410/include/mach/memory.h &

在smdk2410_init的定义中s3c_i2c0_set_platdata(NULL);这一句的下面添加：
s3c24xx_fb_set_platdata(&s3c2410_lcd_info);
7. gedit arch/arm/plat-s3c24xx/common-smdk.c &
将结构定义mtd_partition smdk_default_nand_part由：
static struct mtd_partition smdk_default_nand_part[] = {
[0] = {
.name = "Boot Agent",
.size = SZ_16K,
.offset = 0,
},
[1] = {
.name = "S3C2410 flash partition 1",
.offset = 0,
.size = SZ_2M,
},
[2] = {
.name = "S3C2410 flash partition 2",

},
[7] = {
.name = "S3C2410 flash partition 7",
.offset = SZ_1M * 48,
.size = SZ_16M,
}
};
改成：
static struct mtd_partition smdk_default_nand_part[] = {
[0] = {
.name = "S3C2410 flash partition 1",
.offset = 0,
.size = SZ_32M,
},
[1] = {
.name = "S3C2410 flash partition 2",
.offset = SZ_32M,
.size = SZ_32M,

},
[7] = {
.name = "S3C2410 flash partition 7",
.offset = SZ_1M * 48,
.size = SZ_16M,
}*/
};

static struct s3c2410_nand_set smdk_nand_sets[] = {
[0] = {
.name = "NAND",
.nr_chips = 1,
.nr_partitions = ARRAY_SIZE(smdk_default_nand_part),
.partitions = smdk_default_nand_part,
},
