linux驱动编译时提示缺少asm/types

虚伪世界

原子哥 我想问一下我用vscode编译第一个linux驱动时编译出现以下问题该怎么解决（在目录下确实没有asm这个文件夹） ：
book@100ask:~/lichee-pi/projects/1_chrdevbase$ make
make -C /home/book/lichee-pi/linux_kernels/linux-5.10 M=/home/book/lichee-pi/projects/1_chrdevbase modules

仰望星空之云

编译器用错了，你的应该是用的ubuntu自带的编译器了，属于x86架构的编译器，不是ARM架构的编译器，要用教程4.9.4版本的那个。
不要直接执行make，试试:
配置：
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- 后面加配置文件名


编译：
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
