㈠ 如何用doxygen生成文檔
在代碼中加入文檔 這個是第一步,也是最重要的一步,直接影響著文檔的優與劣.
Doxygen是一個比較成熟的工具了,它有非常詳細且專業的文檔.
文檔是寫在代碼當中的,以注釋塊的形式,為了區分代碼中的正常注釋,訪文檔需要用特殊的形式的注釋塊來呈現.Doxygen支持多種文檔注釋塊:
javadoc形式的:/** * ... */QT形式的/*! * ... */或者,這樣/// /// ... ///或者,這樣//! //! .. //!後二種有點非主流,不建議使用.推薦使用前面二種.當然,配置了某些特殊的選項也可以使用其他格式.
當Doxygen看到這種形式的注釋塊時就會把它從代碼中抽取出來,生成HTML形式的文檔.
為了讓文檔更且有可讀性,表達出更多的信息,Doxygen就定義了很多的命令,常用的有:
\file 告訴Doxygen這是某個文件的文檔塊\enum 給一個enum類型加文檔\struct 給一個結構體加文檔\param 函數的參數\return 函數的返回值\see 交叉參考\brief 簡介,用於概覽時控制在一行以內,可以空一行,然後寫更多的詳細的內容\code \endcode 示例代碼\note 注意事項\par HTML中的
需要注意的是,這些命令也可以用javadoc格式的來寫如@file, @enum, @return等.但建議用標准格式,因為\只需要敲一下,而@需要敲二下,另外就是並不是所有的命令都支持javadoc格式.
還有就是如果想寫交叉引用可以在前面加個#就會自動轉為相應的鏈接,直接上個例子就都明白了:/** * \brief Obtain current list of path * * \param [out] paths a pointer to an array of strings * \param [out] count indicating the count of path. * * \note * This function will allocate memory for path array. So caller must free the array, but should not free each item. * * \return #API_RESULT_CODE indicating whether this call success or failed. * * \par Sample code: * \code * char **path = NULL; * int count = 0; * test_get_paths(&path, &count); * // use the path * free(path); * path = NULL; * \endcode */ int test_get_paths(char ***paths, int *count);配置Doxygen Doxygen需要一個配置文件來告訴Doxygen一些選項.配置文件就是一個純文本文件,格式跟標準的linux配置文件一樣:一行一個配置項,前面是配置項的名字,然後是等號後面就是配置項的值了.以#開頭都是注釋.Doxygen的選項特別的多,不可以手動的去寫,通常都是編輯一個現有的模板,這個模板可以用Doxygen來生成:
doxygen -g config-filename
PROJECT_NAME 項目的名字,一定要改成你項目的名字PROJECT_NUMBER 編號,通常使用項目的版本號OUTPUT_DIRECTORY 文檔輸出存放目錄,建議修改,比如docPROJECT_BRIEF 項目的描述,會出現文檔每一頁的上面,控制在一行80字元內(越短越好)EXTRACT_*** 打頭的選項要仔細讀,如果是API文檔,則這些全都要設成NO,這樣就僅抽取特定文檔塊內的內容. 其他的選項都可以不改,用默認的就成.
生成文檔 這步最簡單,如果前面都就緒了,僅需要運行命令即可:
doxygen config-filename
後,文檔就會出現在所指定的輸出目錄中.
doxygen會列印出日誌信息.為了保證質量,最好把把的Warning都修正掉.(這跟修正代碼的所有編譯警告一個道理).上面例子生成的文檔:int test_get_paths(char *** paths, int * count ) Obtain current list of path. Parameters:[out]pathsa pointer to an array of strings[out]countindicating the count of path.Note:This function will allocate memory for path array. So caller must free the array, but should not free each item.Returns:API_RESULT_CODE indicating whether this call success or failed.Sample code:char **path = NULL; int count = 0; test_get_paths(&path, &count); // use the path free(path); path = NULL; 完整示例下載

㈢ Linux下源代碼編譯 沒有那個文件或目錄
文件在./src/modelRection/，但是makefile裡面寫的是-I.src/modelRction/，？？
㈣ 開發B/S網頁（進銷存）系統，那款開發工具最方便簡單實用
Linux開發工具就C＋＋開發工具而言，與Windows下微軟（VC， VS2005等）一統天下相比，Linux/Unix下C＋＋開發，可謂五花八門，各式各樣。Emacs, vi, eclipse, anjuta，kdevelop等層出不窮。
Windows下
開發工具多以集成開發環境IDE的形式展現給最終用戶。例如，VS2005集成了編輯器，宏匯編ml，C /C++編譯器cl，資源編譯器rc，調試器，文檔生成工具, nmake。它們以集成方式提供給最終用戶，對於初學者而言十分方便。但是，這種商業模式，直接導致用戶可定製性差，不利於自動化，集成第三方工具的能力弱。例如，無法定製一些宏來處理一些重復操作；體會不到自動化makefile一步到位快感；無法遠程登錄到伺服器上進行開發；無法使用某種」粘合劑」來把第三方工具（例如，文本工具，字元串工具）有效地調用起來。可以說，良好的商業支持和傻瓜式開發，是它們主要的優點。
在linux下
Linux開發工具被切割成一個個獨立的小工具。各自處理不同的問題。例如，編輯器（emacs, vim)用來進行編輯程序的，調試器（gdb)用來調試程序，編譯器（GCC）用來編譯和鏈接程序的，性能分析工具（gcov, gprof)用來優化程序的，文檔生成器（doxygen）用來生成文檔的。同時，還有一些系統工具和系統知識，我們是很有必要了解的：程序自動化機制 makefile，系統粘合劑shell，系統查找工具grep, locate, find。其它的工具（例如ctags， OCI公司的MPC等等），一旦熟練掌握，它們將成為你手中的利器。
本文主要是一些針對Linux開發工具使用的經驗之談。由於，工具品種繁多，我們沒有能力也沒有必要一一介紹。對於Linux下IDE工具，例如 eclipse, anjuta等，它們雖然也很實用，但是使用起來比較簡單，而且目前還算不上主流。所以，它們將不被著重介紹。同時，本文也不打算寫成各個工具的操作手冊，只著眼於介紹各個工具的想要解決的問題、運行機理和主要特性。

㈥ 怎麼在linux下查看某個函數在c++下的用法
GNU GCC 提供了一份關於 MAN 格式的 C++ 標准庫的文檔，可以在其鏡像點（http://gcc.gnu.org/mirrors.html）中下載。具體的路徑是：libstdc++/doxygen/libstdc++-man-xxxxxx.tar.bz2，可找一個最新日期的下載。展開包之後將 man/man3 中的所有文件拷貝到系統上已經存在的一個 man/man3 目錄中即可使用。
可首先 man C++Intro 閱讀 Introction to the GNU libstdc++-v3 man pages。
對於 cout，你需要知道它是 std::ostream 類的一個對象，所以應該 man std::ostream。

㈧ linux系統中常用開發工具有哪些
編輯器（emacs,
vim
vim用的較多)用來進行編輯程序的，調試器（gdb)用來調試程序，編譯器（GCC）用來編譯和鏈接程序的，性能分析工具（gcov,
gprof)用來優化程序的，文檔生成器（doxygen）用來生成文檔的
當然其它的還有很多，這個要根據你的開發來的。
望採納！
㈨ 在linux下用什麼工具寫C++代碼
在Linux下，C++開發工具被切割成一個個獨立的小工具。各自處理不同的問題。例如，編輯器（emacs， vim）用來進行編輯程序的，調試器（gdb）用來調試程序，編譯器（GCC）用來編譯和鏈接程序的，性能分析工具（gcov， gprof）用來優化程序的，文檔生成器（doxygen）用來生成文檔的。
同時，還有一些系統工具和系統知識，我們是很有必要了解的：程序自動化機制 makefile，系統粘合劑shell，系統查找工具grep， locate， find.其它的工具（例如ctags， OCI公司的MPC等等），一旦熟練掌握，它們將成為你手中的利器。
