关于linux和arm的问题

最近看linux设备驱动开发详解：
……
由于linux2.6.15.5直接提供了S3C2410评估版SMDK2410的支持，因此为它编译linux 2.6.15.5非常快捷，首先运行以下命令：
make ARCH=arm CROSS_COMPILE=arm-linux-menuconfig （指定体系结构为ARM，交叉编译器为arm-linux-gcc）
在弹出的菜单中直接选择“Load an Alternate Configuration FIle”，把默认配置文件路径输入即可
……
但是不管我是否准备了交叉编译链arm-linux-gcc，都是不行，都说没有找到arm-linux-menuconfiggcc！
然后我觉得可能不对，就改成
make ARCH=arm CROSS_COMPILE=arm-linux-
但是还是说arm-linux-gcc，而事实上我的环境里面是可以实行arm-linux-gcc的命令的！
还有就是，linux设备驱动详解这本书之前都没有讲过交叉编译，突然来了这个命令，是不是redhat9里面本身带有交叉编译链啊！那个系统我没用过，不清楚啊

恩，好，呵呵

内核没有配置好，应该是。
仔细看看文档，或者让你们同事在旁边给你示范一下吧。

恩，确实如white兄说的，该打上那个空格的！我这是交叉链没有做好！后来做好了就好了！
不过蛮奇怪的！
我后来
make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig
可以成功，没有问题！
而我
make ARCH=arm CROSS_COMPILE=arm-linux-（就相当于直接make）
反而倒是出现一大堆错误！

感觉蛮奇怪的！按理说不是一样的么！

确实，容易漏打

应该是[code]make ARCH=arm CROSS_COMPILE=arm-linux- menuconfig[/code]吧。
注意 menuconfig 之前的那个空格。

下面的文字取自内核的 Makefile ，你可以参考一下：

锟斤拷锟斤拷:

# Cross compiling and selecting different set of gcc/bin-utils
# ---------------------------------------------------------------------------
#
# When performing cross compilation for other architectures ARCH shall be set
# to the target architecture. (See arch/* for the possibilities).
# ARCH can be set during invocation of make:
# make ARCH=ia64
# Another way is to have ARCH set in the environment.
# The default ARCH is the host where make is executed.

# CROSS_COMPILE specify the prefix used for all executables used
# during compilation. Only gcc and related bin-utils executables
# are prefixed with $(CROSS_COMPILE).
# CROSS_COMPILE can be set on the command line
# make CROSS_COMPILE=ia64-linux-
# Alternatively CROSS_COMPILE can be set in the environment.
# A third alternative is to store a setting in .config so that plain
# "make" in the configured kernel build directory always uses that.
# Default value for CROSS_COMPILE is not to prefix executables
# Note: Some architectures assign CROSS_COMPILE in their arch/*/Makefile

你改下环境变量试试
