更新時(shí)間：2016年11月16日 10:43:01 作者：bladestone

最近經(jīng)常使用ubuntu，難免會(huì)遇到各種各樣的問(wèn)題。所以想著記錄下來(lái)，方便自己和大家以后需要的時(shí)候查看參考，文中介紹的很詳細(xì)，相信對(duì)大家學(xué)習(xí)或者使用Ubuntu能有一定的參考借鑒價(jià)值，感興趣的朋友們下面來(lái)一起看看吧。

一、下載 http://www.tcpdump.org/#latest-release，下載libcap-1.8.1.tar.gz, 解壓縮之后

錯(cuò)誤１: ./configure

checking for getifaddrs... yes 
checking ifaddrs.h usability... yes 
checking ifaddrs.h presence... yes 
checking for ifaddrs.h... yes 
checking for socklen_t... yes 
checking for getaddrinfo... yes 
checking whether to build optimizer debugging code... no 
checking whether to build parser debugging code... no 
checking whether we have DAG API headers... no

checking whether we have Myricom Sniffer API... no 
checking whether TurboCap is supported... no 
checking for flex... no 
checking for lex... no 
configure: error: Neither flex nor lex was found.

核心錯(cuò)誤信息為：　

error: Neither flex nor lex was found.

解決辦法：　sudo apt-get install flex bison

然后輸入==> sudo make install , 進(jìn)行安裝

錯(cuò)誤２：

checking for gcc... gcc 
checking whether the C compiler works... yes 
checking for C compiler default output file name... a.out 
checking for suffix of executables...  
checking whether we are cross compiling... no 
checking for suffix of object files... o 
checking whether we are using the GNU C compiler... yes 
checking whether gcc accepts -g... yes 
checking for gcc option to accept ISO C89... none needed 
checking for pcap_open_live in -lpcap... no 
error: pcap library not found!

問(wèn)題解決：

sudo apt-get install libsqlite3-dev libpcap-dev

然后重新嘗試新的命令，即可解決上述錯(cuò)誤

二、中文模式下切換回英文模式？

修改/etc/default/locale文件的語(yǔ)言值。

將LANG zh_CN.UTF-8修改為en_US.UTF-8 , LANGUAGE zh_CN:zh修改為en_US:en

三、英文模式下開(kāi)機(jī)自動(dòng)啟動(dòng)IBUS中文輸入法。

英文模式下，ibus不能自動(dòng)啟動(dòng)。每次輸入中文都得手動(dòng)啟動(dòng)。這個(gè)讓人不能接受。google一下，兩種方法。

方法1：system settings->Languange-support->keyboard input method system ->ibus

這種方法我沒(méi)試驗(yàn)成功。如圖所示，選擇了沒(méi)有保存按鈕。我以為是默認(rèn)保存的。但是關(guān)了在打開(kāi)發(fā)現(xiàn)還是沒(méi)有選擇上。有可能語(yǔ)言包沒(méi)有按完整的語(yǔ)言，每次進(jìn)入語(yǔ)言設(shè)置，都會(huì)提示語(yǔ)言包沒(méi)有安裝完整。

方法2：添加ibus設(shè)置為開(kāi)機(jī)啟動(dòng)的應(yīng)用

system->preferences->startup application
