Module 编译示例内核模块时出错
我试图使用init和cleanup函数的替代名称从《Linux内核模块编程指南》中编译一个示例模块，但我不断收到以下错误：Module 编译示例内核模块时出错,module,kernel,Module,Kernel,我试图使用init和cleanup函数的替代名称从《Linux内核模块编程指南》中编译一个示例模块，但我不断收到以下错误： make -C /lib/modules/4.15.0-54-generic/build M=/media/aaron/GoogleDrive/School/CSC239/project/LKM/hello3 modules make[1]: Entering directory '/usr/src/linux-headers-4.15.0-54-generic' C

我做错了什么？看起来init.h中有一个错误，但我无法编辑它。非常感谢您的帮助。看看您的最后几行：
module_init（hello_3_init）；
模块初始化（hello\u 3\u退出）；
module_init模块\u退出module_init（hello_3_init）；
模块退出（你好3退出）；
希望我回答这个问题还来得及 看看你的最后几行：
module_init（hello_3_init）；
模块初始化（hello\u 3\u退出）；
module_init模块\u退出module_init（hello_3_init）；
模块退出（你好3退出）；
