CLFS在最后编译Kernel的时候LINUX_ARM_ARCH is not defined

用CLFS1.0.0做linux在arm上的移植,在Youbest大虾的帮助下比较顺利,但最后编译Kernel的时候总是提示"__LINUX_ARM_ARCH__" is not defined,就完全不知道是怎么回事的了,大家有建议么,谢谢!!!

这个问题是由于没有指定特定CPU类型导致的。
在 System Type 里的有些选项是系列性质的，选择后，必须还要指定特定的 Machine Type 或者
Processor Type 。 比如，指定 ARCH_S3C2410 并没有指定CPU类型，还要指定 Machine Type。

cp arch/arm/configs/s3c2410_defconfig .config
然后再配置吧
