linux - 如何修复未在 CENTOS 上构建的 802.11 Linux STA broadcom 驱动程序？

Question

我已经安装了 CENTOS 6.3。我的机器是 Dell Studio。我有以下无线 broadcom 型号。

[root@treasure hybrid_wl]# lspci | grep -i wireless
03:00.0 Network controller: Broadcom Corporation BCM4313 802.11b/g/n Wireless LAN Controller (rev 01)

我从http://www.broadcom.com/support/802.11/linux_sta.php得到了这个驱动的源代码.

我的机器内核是

[root@treasure hybrid_wl]# uname -r
2.6.32-358.18.1.el6.x86_64

从 http://www.broadcom.com/support/802.11/linux_sta.php 构建包时. 我收到以下错误。

KBUILD_NOPEDANTIC=1 make -C /lib/modules/`uname -r`/build M=`pwd`

我该如何解决这个问题？我错过了什么？我还更新了 Broadcom 支持组电子邮件 ID，此处为 linux-wlan-client-support-list@broadcom.com。 Broadcom 是一家领先的公司，我希望他们能在这方面提供帮助。我也给他们发了电子邮件。 Broadcom 只能在这里分享他们的解决方案，让世界从中受益。

致博通， 我已经在堆栈溢出上发布了这个，因为每个人都可以利用它。目前，我无法在笔记本电脑上使用 WIFI。我坚持使用有线连接。请帮助我，以便我可以使用 WIFI。当什么都没有构建时，我在最新版本中尝试了以下操作。

make API=WEXT (deprecated) ----> 我正在关注自述文件。

这会检测到可用的 wifi 网络，但无法连接到 AP。看起来这需要无线扩展工具。

做，我需要为它安装任何东西。或者您是说，不要使用已弃用的构建规则，而是修复构建错误？您对此有何建议？

建议，我可以跟进。

关键在这里: /home/joshis1/hybrid_wl/src/wl/sys/wl_cfg80211_hybrid.c:2122: 错误:函数“cfg80211_roamed”的参数太少

如果你检查 wl_cfg80211_hybrid.c ~line 2122

cfg80211_roamed(ndev,
#if LINUX_VERSION_CODE > KERNEL_VERSION(2, 6, 39)
                    NULL,
#endif
    (u8 *)&wl->bssid,  conn_info->req_ie, conn_info->req_ie_len,
    conn_info->resp_ie, conn_info->resp_ie_len,        GFP_KERNEL);
    WL_DBG(("roaming result\n"));
}

虽然我运行的是带有 2.6.32 的 RHEL6.5，但它运行的是一个需要额外参数的 net/cfg80211.h 版本，所以我需要将行更改为: #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 32) - 或者完全删除 if/endif。不幸的是，它并不止于此，如果在 wl_cfg80211_hybrid.c 中，那大约有十几个 KERNEL_VERSION 需要更改。

一旦完成(您可以测试但运行“make”并返回并修复错误)它确实可以正常编译和安装。我现在正在使用 WPA 等运行它。正如预期的那样。似乎只是 RedHat 从更新的内核中引入了一些 cfg80211 到 2.6.32 混淆了模块。
