LDD3的scull_load出错

klanet

大家好，刚学linux。目前在看LDD3。
运行里面的例程，错误很多，google之后都能解决。现在就是创建节点的时候出错了。
完全搞不懂是什么情况。
请大家多多指点。
内核版本是：

貌似awk就出错了？你把awk拿出来运行一下

klanet

解决了。
1.要apt-get install gawk.ubuntu里面的awk行为有点诡异
2.把major=$(awk "\\$2==\"$module\" {print \\$1}" /proc/devices)
改为
major=$(awk "\$2==\"$module\" {print \$1}" /proc/devices)
