make modules的问题，mini2440开发板

请问，我在编译hello modle驱动的时候遇到这样的错误，怎么回事？

这是开发板用的内核，肯定没问题，我想应该是我哪里配置有问题，或者我不会在makefile里面配置gcc选项引起的，makefile里面怎么配置gcc选项？

drivers/media/radio/radio-maestro.c:219: error: invalid type argument of `->'

这个地方应该是指针用法有误吧。

BTW，你得保证你的makefile使用的编译器是交叉编译器。一般都是在Makefile的开头会指定使用那个编译器的。

原来是make menuconfig的时候没有装入内核配置文件，现在装入了，问题就没了。这是在文档的后面说的，哎，这文档真是害人啊

呵呵，不是文档害人。而是往往我们都没有耐心系统的看一下文档。

应该学会自己思考，而不是一有问题就提问

你怎么知道我一有问题就提问？我是按照文档一步一步来做的，遇到这个问题后，我首先就把出错的文件看了下，那是个音频的驱动代码，我没看懂，后来又试图看看Makefile里面的配置，没发现什么问题，我就纳闷了，明明这运行的内核就是由这个文件编译的，怎么我来编译就出问题？肯定是我哪里配置的问题，我没想到这个配置是在下一章讲到了。
