交叉编译linux内核问题解决（备忘）

1. make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig

 *** Unable to find the ncurses libraries or the
 *** required header files.
 *** 'make menuconfig' requires the ncurses libraries.
 ***
 *** Install ncurses (ncurses-devel) and try again.
 ***
make[1]: *** [scripts/kconfig/dochecklxdialog] 错误 1
make: *** [menuconfig] 错误 2

解决方法：
sudo apt-get install ncurses-dev

2. 使用busybox制作rootfs
make ARCH=arm CROSS_COMPILE=arm-linux-

networking/interface.c:818: error: 'ARPHRD_INFINIBAND' undeclared here (not in a function)
make[1]: *** [networking/interface.o] Error 1
make: *** [networking] Error 2

解决办法：

在“networking/interface.c”添加：

#define ARPHRD_INFINIBAND 32 /* InfiniBand */

3.使用mini2440，采用nfs文件系统，linux启动参数为
"console=ttySAC0 root=/dev/nfs nfsroot=192.168.0.229:/home/yigc/rootfs_2440 ip=192.168.0.230:192.168.0.229:192.168.0.229:255.255.255.0:"

Warning: unable to open an initial console.
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.

解决办法：
创建rootfs过程中，在/dev目录下手动创建如下节点：

mknod -m 660 null c 1 3

mknod -m 660 console c 5 1

4.

使用mini2440，采用nfs文件系统，linux启动参数为
"console=ttySAC0 root=/dev/nfs nfsroot=192.168.0.229:/home/yigc/rootfs_2440 ip=192.168.0.230:192.168.0.229:192.168.0.229:255.255.255.0:"

can't open /dev/tty3: No such file or directory
can't open /dev/tty2: No such file or directory
can't open /dev/tty4: No such file or directory

解决办法：

 ln -sf /dev/null /dev/tty2
 ln -sf /dev/null /dev/tty3
 ln -sf /dev/null /dev/tty4

5.
编译minigui时候，设置FB时出错：
NEWGAL>FBCON: Can't open /dev/tty0: No such file or directory 

NEWGAL: Set video mode failure.

InitGUI: Can not initialize graphics engine!

解决办法：

内核配置时候选择下面的选项
Graphics support --->   
Support for frame buffer devices 
Virtual Frame Buffer support (ONLY FOR TESTING!)
Console display driver support --->
Framebuffer Console support
