好,开始安装.
首先编译源码:
[e4gle@openbsd29]# gcc -D_KERNEL -I/sys -c chardev.c
[e4gle@openbsd29]#
安装模块:
[e4gle@openbsd29]# modload -o ourdev.o -eourdev -p ./dev-install.sh chardev.o
Module loaded as ID 0
created device /dev/ourdev, major number 29
crw-r--r--1 rootwheel 29, 0 Jul 10 05:16 /dev/ourdev
[e4gle@openbsd29]#
看看日志确定模块是否被正常加载:
[e4gle@openbsd29]# dmesg
