TP-LINK TL-WN725N ubuntu13.04 驱动问题解决
linux
新的一些硬件驱动往往第一时间不在 Linux 上面发布, 这也是 Linux 推广到普通人群的一个主要问题之一.
这不, 最近刚解决一个驱动问题, 也发现别人都遇到过, 发在上面以期帮助大家少走弯路.
关键词: 8188eu, kernel 3.8.0
先声明一点, 有些问题看似相同, 但可能有本质差别, 此文解决的环境如下:
TP-LINK TL-WN725N 在 unbuntu 13.04 中的驱动安装问题. 本质问题是 realtek 8188eu 无线驱动在 linux kernel 3.8.0 中的安装问题.
OK, 开始,
第一步, 先查问题, lsusb 查到硬件id为 0bda:8179, 再到google之, 知道是 8188eu 的驱动.
第二步, 下载驱动, 正常搜索 realtek官网, 可以找到, 但一看, nnd, 是2.6内核的, 3.0以上是不可用的.
继续找, 发现这里: https://github.com/Red54/linux-shumeipai2/tree/sunxi-3.0/drivers/net/wireless/rtl8188eu 这个已经支持3.x. 好, 使用
git clone --depth 1 xxx_url
下载之.
第三步, 编译安装, 驱动的编译安装也很简单, 无非就是
make
make install
depmod -a
modprobe xxx
但是, 这里才出现问题的关键, 8188eu 在 3.5.x 内核以下版本都没有问题, 3.5.x 以上就出问题了:
error: implicit declaration of function ‘daemonize’ [-Werror=implicit-function-declaration]
这个问题是由于 3.5.x 以上内核去掉了 daemonize 这个函数, 导致无法顺利编译( 当然这是查了N多资料, 搜索了对应的头文件 ),
解决方法很简单, 删掉它就可以了:
diff --git a/include/osdep_service.h b/include/osdep_service.h
index ed2dae5..e9acb0d 100755
--- a/include/osdep_service.h
+++ b/include/osdep_service.h

{
#ifdef PLATFORM_LINUX
- daemonize("%s", name);
+ //daemonize("%s", name);
allow_signal(SIGTERM);
#endif
#ifdef PLATFORM_FREEBSD
好了, 重新编译, 安装即可.
因为本篇不是新手解决问题的方法, 只写了思路和关键步骤, 这里有一个参考内容, 步骤写的很全, 中间加上我这里的修改就可以了, 你可以参考下: http://peppermintos.net/viewtopic.php?f=8&t=5619

我最后还是在树莓派的官方博客里找到了有个叫MrEngman的雷锋把几乎所有树莓派的版本的8188eu的驱动都编译好的ko放到网上供大家下载，然后问题就解决了，不过还是不知道他怎么实现的。
另外楼主创业做啥呢？

@Kevin
这里是 3.8 内核的解决方法，看你们的描述是3.12内核的变更导致的其它错误，最好去找找有没有兼容新内核的驱动，如果还是没有，就只能自己动手去改代码了。

我遇到了和楼上一样的问题 求解。。。 那几个函数貌似全部都变了。楼主的系统版本是多少额

我3.12.22+的树莓派下编译8188eu的驱动，结果你提到的错误，按照你的修改以后还有错误：
