linux编译出错

在x86上做出来了，但是在ARM上却出现了很多问题，有内核代码准备的问题，有模块代码问题，也有Makefile的问题。看似不起眼的角色，出了问题也很纠结。

第一种：内核代码没有准备好

[root@localhost module]# make

make -C /opt/kangear/kernel/linux-2.6.32.2 M=/root/桌面/kangear/module modules

make[1]: Entering directory `/opt/kangear/kernel/linux-2.6.32.2'

ERROR: Kernel configuration is invalid.

Run 'make oldconfig && make prepare' on kernel src to fix it.

这种是下载的很干净的内核，配置都没有配置；或是配置了，有.config但是没有make zImage。编译一下，不为用这个zImage,只是为了更好的编译内核模块。

其实看实质就是找不到auto.conf，这个其实已经有了，就是.config，但是如果不想手动来拷贝可以假装make zImage（如下），这里就可以了，完整的编译一个内核只为了这个一个配置文件，也太浪费了。

这大多是模块代码的错误，里边有中文相关的一些东西了，一些符号。代码是在博客上拷贝的或者是在win下用ue编辑的，直接拷贝到Linux中就会有这种问题。唯一的办法就是重新打一编代码了。目前还没有找到合适的方法。（语法问题就不提了）

第三种：模块Makefile语法错误

[plain] view
plain copy

[root@localhost hello]# make

make: Nothing to be done for `default'.

[root@localhost hello]#

对应的makefile是命令为：

[plain] view
plain copy

default:

make -C $(KERNELDIR) M=$(PWD) modules

make前边应该有一个tab键。或者是make前边是空格而不是tab。
