编译linux内核出现的错误 [复制链接]

小弟初学arm，按照书上的一些介绍做好了linux内核配置，在make zImage时，出现下面问题:不知道是什么原因，请高手帮忙解答一下。。。

warning: (NETFILTER_XT_MATCH_REALM) selects NET_CLS_ROUTE which has unmet direct dependencies (NET && NET_SCHED)

make: *** [prepare0] Error 2

出错信息：CC      kernel/bounds.s
cc1: error: invalid option `abi=aapcs-linux'
make[1]: *** [kernel/bounds.s] Error 1
make: *** [prepare0] Error 2
原因：旧编译器可能是用OABI的，而配置内核时又选择了使用EABI的，修改内核配置：
    Kernel Features ---->Use the ARM EABIto compile the kernel
不选该项。

把那个选项去掉后，能够往下编译了，编译到后面出现了这个错误;
