一、环境介绍
操作系统: ubuntu18.04 64位
二、编写Makefile(PC机)先输入uname -r命令查看当前系统的版本.
root@wbyq:/mnt/hgfs/linux-share-dir/linux_c/usb_dev_ubuntu# uname -r
5.3.0-40-generic
查看系统内核的路径是否存在:
root@wbyq:/mnt/hgfs/linux-share-dir/linux_c/usb_dev_ubuntu# ls /usr/src/
linux-headers-5.3.0-40 linux-headers-5.4.0-53-generic linux-hwe-5.4-headers-5.4.0-47
linux-headers-5.3.0-40-generic linux-hwe-5.4-headers-5.4.0-42 linux-hwe-5.4-headers-5.4.0-48
linux-headers-5.4.0-48-generic linux-hwe-5.4-headers-5.4.0-45 linux-hwe-5.4-headers-5.4.0-53
根据当前系统的版本，确定对应的路径: /usr/src/linux-headers-5.3.0-40
root@wbyq:/mnt/hgfs/li
