楼主有一块卡皇 USB 网卡，Realtek 8187L 系列，09 年购入，现在依旧在服役。虽然这款无线网卡的驱动已经内置到内核里了，但是却有不少的毛病，比如信号不好，有掉线的情况发生，于是我想我几年前也编译过这个驱动，索性编译一个好了，没想到这却是折腾的开始。。。好了，题外话少说，现在进入正题
在 Realtek 的官方网站上有 8187 系列的 Linux 版本驱动下载，是 2012 年更新的版本，支持 3.0~3.2 的内核。但是内核更新了这么久，官方的驱动是否还能使用？在我的 openSUSE 13.1 下进行编译，情况如下

官方的驱动早已不能编译成功。怎么破？
虽然我是小白，看不懂编译是什么错误，不过有 Google 嘛。于是上网搜索了一下，发现在 Ubuntu 论坛上有人提出了解决方案 ubuntuforums.org/showthread.php?p=12775665#post12775665 在"r8187.h" 文件的开头加入
#ifndef __devinit
#define __devinit
#define __devexit
#endif
更改之后满怀信心再次编译，可还是错误：

这回我发现是由于没有申明 create_proc_entry 这个函数，去 Google 一搜发现在 3.10 内核之后将 create_proc_entry 去除了，改为 proc_create 函数了。于是我将函数一一进行更改，改完之后编译还是出错，这次是什么错误呢

事情到这里我彻底没有办法了。。由于我对系统编程知之甚少，而且对硬件驱动完全不知，实在是没有办法再改动源代码了。在此向论坛的各位大牛求助，能否帮忙一起将此驱动在 3.10 版本内核和之后的版本中编译通过。先行谢过各位！
