如何修復不在CENTOS上構建的802.11 Linux STA broadcom驅動程序？

Question

我已經安裝了CENTOS 6.3。我的機器是Dell Studio。我有以下無線broadcom模型。

[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) 

我從http://www.broadcom.com/support/802.11/linux_sta.php得到了此驅動程序的源代碼。

我的機器的內核是

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

雖然從http://www.broadcom.com/support/802.11/linux_sta.php構建軟件包。 我收到以下錯誤。

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

我該如何解決這個問題？我錯過了什麼？我還更新了Broadcom支持小組的電子郵件ID，這裏是linux-wlan-client-support-list@broadcom.com。 Broadcom是一家領先的公司，我希望他們在這裏幫助。我也通過電子郵件發送了他們。 Broadcom只能在這裏分享他們的解決方案，這樣世界才能從中受益。

給博通， 我已經發布了堆棧溢出，因爲每個人都可以獲得它的優勢。目前，我無法在筆記本電腦上使用WIFI。我堅持使用有線連接。請幫助我，讓我可以使用WIFI。當沒有什麼東西正在建設，我嘗試了以下最新版本。

使API = WEXT（不建議使用）---->我正在關注自述文件。

這會檢測可用的wifi網絡，但無法連接到AP。看起來這需要無線擴展工具。

是的，我需要爲它安裝任何東西。或者你說，不要使用過時的構建規則，而是修復構建錯誤？無論你對此有何建議？

建議，我可以關注它。

的關鍵是在這裏： /home/joshis1/hybrid_wl/src/wl/sys/wl_cfg80211_hybrid.c:2122：錯誤：參數太少函數「cfg80211_roamed」

如果選中wl_cfg80211_hybrid。C〜2122行

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")); 
} 

雖然我與2.6.32它的運行版本網/ cfg80211.h的一個期望的額外的參數，所以我需要行改爲運行RHEL6.5： #if LINUX_VERSION_CODE >= KERNEL_VERSION(2, 6, 32) - 或者完全刪除if/endif。不幸的是它並不止於此，如果在wl_cfg80211_hybrid.c中有大約十二個KERNEL_VERSION需要更改。

一旦完成（你可以測試但運行'make'並返回並修復錯誤），它會編譯並安裝正常。我正在用WPA運行它，如預期的那樣。看起來只是RedHat將一些cfg80211從更新的內核引入到2.6.32中，導致模塊混淆。

上週我和朋友的CentOS 6.4 Acer筆記本電腦（BCM 43227 WiFi）有完全相同的問題。 Broadcom驅動程序只能使用API​​ = WEXT選項（否則，您引用的錯誤信息相同）構建，但只能與「開放」WiFi網絡，而不是WPA/WPA2（不知道WEP）有關。在/var/log/wpa_supplicant.log中，當嘗試連接到WPA網絡時，我收到了錯誤消息association request to the driver failed，NetworkManager只會繼續詢問密碼。

除了直接編譯Broadcom驅動程序外，我還嘗試按照ELRepo wl-kmod Howto（通過CentOS wiki）建議構建RPM軟件包，但也失敗了（Broadcom文件名與預期的RPM不同）。

本週末我又看了一遍電腦，發現ELRepo Howto鏈接的RPM文件發生了變化，文檔本身在9月26日更新。所以我再次嘗試使用較新的RPM，正好遵循instructions，這一次它工作正常。有一個安裝了wl.ko內核模塊的RPM文件。加載它通過modprobe wl，之後，NetworkManager發現我的WPA2 WiFi和第一次嘗試連接。
