带有链接器错误的ascend mate的android内核

Question

我做了一个从4.1到4.4的内核移植，但我得到了这个错误，我知道这个错误是由链接器引起的，但我不知道在哪里找到错误，因为这些文件已经编译了，很抱歉我的英文不好，这是终端中的命令和结果，提前谢谢：

Answer 1

我在某处读到过这个问题并解决了它，只是我添加了这些变量或函数的定义，因为“extern”不适用于它自己。

对于行：

arch/arm/mach-k3v2/built-in.o:iomux.c:function get_active_block_table.part.0: error: undefined reference to 'g_current_board_id'

只是将全局“类型”g_current_board_id添加到iomux.c文件中；

或者对于函数："type“functionname(type args) {}

这就是全部
