Linux中C++動態庫編譯的示例分析

這篇文章主要介紹Linux中C++動態庫編譯的示例分析，文中介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！

1 編譯

 問題1： configure:error: "Error: libcrypto required."    

解決：apt-getinstall libssl-dev

 問題2：uint32_tdoes not name a type

解決：

   uint32_t定義文件在stdint.h，通過whereis stdint.h

   stdint.h: /usr/include/stdint.h

說明在標準的include路徑下，將出現編譯錯誤的源碼文件中添加#include<stdint.h>

問題3：Makefile文件的BOOST庫路徑指定錯誤

解決：

MakeFile文件中:BOOST_DIR = /usr/local/include/boost

而實際的情況卻是：BOOST_DIR=/usr/include/boost

 # apt-get installlibboost-dev

已經安裝成功，但是不清楚安裝的位置

查找本地boost庫的安裝目錄：

whereis boost

boost:/usr/include/boost

問題 4：ntohs 存在未定義的編譯錯誤

解決：

包含頭文件#include<arpa/inet.h>

問題5：編譯例子出現thrift庫函數大量未定義的編譯錯誤

解決：

主要是鏈接-lthrift必須放在CppClient.cppCppServer.cpp的后面，修改Makefile文件，調整兩者的順序即可。當某一個源碼文件編譯找不到函數定義的時候，只會往后查找函數定義

問題6：

解決：添加-DHAVE_NETINET_IN_H
