boost asio示例編譯錯誤

Question

我是Boost的非常初學者，並嘗試通過此鏈接編譯C ++程序： http : //www.boost.org/doc/libs/1_53_0/doc/html/boost_asio/examples.html#boost_asio.examples.http_server_3 （httpserver3例如），因此我嘗試使用以下命令來編譯該項目（在linux [debian]中）：

g ++ -o htserv.exe connection.cpp main.cpp mime_types.cpp request_handler.cpp request_parser.cpp server.cpp

要么

g ++-牆-g -I / usr / local / include / boost connection.cpp main.cpp mime_types.cpp request_handler.cpp request_parser.cpp server.cpp -o htserv

然后我看到這個錯誤：

In file included from connection.cpp:11:0:
connection.hpp:20:23: fatal error: request.hpp: No such file or directory
compilation terminated.
In file included from server.hpp:19:0,
                 from main.cpp:16:
connection.hpp:20:23: fatal error: request.hpp: No such file or directory
compilation terminated.
request_handler.cpp:18:23: fatal error: request.hpp: No such file or directory
compilation terminated.
request_parser.cpp:12:23: fatal error: request.hpp: No such file or directory
compilation terminated.
In file included from server.hpp:19:0,
                 from server.cpp:11:
connection.hpp:20:23: fatal error: request.hpp: No such file or directory

是的，您是對的，我檢查了許可權，並且在我編譯時出現了一個新問題，一個是如此困惑

然后我嘗試使用此命令進行編譯： gcc -I / usr / local / include / boost / -lboost_thread -lboost-asio -lboost_noncopyable -lboost_bind -lboost_logic -lboost_tuple -lboost_array connection.cpp mime_types.cpp main.cpp reply.cpp request_handler.cpp server.cpp -o hserv我遇到此錯誤：

/usr/bin/ld: cannot find -lboost-asio
/usr/bin/ld: cannot find -lboost_noncopyable
/usr/bin/ld: cannot find -lboost_bind
/usr/bin/ld: cannot find -lboost_logic
/usr/bin/ld: cannot find -lboost_tuple
/usr/bin/ld: cannot find -lboost_array
collect2: error: ld returned 1 exit status

然后我嘗試使用此命令g ++ -I /usr/local/include/boost/connection.cpp mime_types.cpp main.cpp reply.cpp request_handler.cpp server.cpp -o hserv -lboost-asio -lboost_noncopyable -lboost_bind -lboost_logic -lboost_tuple -lboost_array

這有錯誤

/usr/bin/ld: cannot find -lboost-asio
/usr/bin/ld: cannot find -lboost_noncopyable
/usr/bin/ld: cannot find -lboost_bind
/usr/bin/ld: cannot find -lboost_logic

您的編譯命令可能應該以g++ -Wall -g -I/usr/include/boost開頭

^{其中-Wall詢問所有警告， -g詢問調試信息， -I/usr/include/boost將include目錄添加到include路徑。}

而且您確實應該使用類似GNU Make的構建器。 現在該學習如何編寫Makefile 。 然后，您應該在Makefile添加一行

  CXXFLAGS= -Wall -g -I/usr/include/boost

如果request.hpp是當前目錄中的您自己的文件（不是某個系統庫中的文件），則應使用雙引號將其包括在內，例如

  #include "request.hpp"

而不使用<request.hpp>或添加-I. 到您的編譯命令。

確保使用pwd和ls命令在正確的目錄中運行編譯。 ls命令應同時顯示request.hpp和connection.cpp 。 如果需要，請使用cd命令（調用chdir（2） syscall）。 花時間閱讀有關bash腳本的更多信息

您可能需要將-v （顯示為編譯啟動的實際程序）和-H （顯示為包含的文件）傳遞給編譯器。

請記住， g++編譯器的參數順序很重要； 源文件應該放在目標文件和庫之前，並且所有文件都應該從高級到低級（例如系統庫）。 閱讀有關調用GCC的章節。 您可能需要一些-L選項。

順便說一句，有幾個可用的HTTP服務器庫，例如libonion （它同時支持HTTP和HTTPS）。

Answer 2

我在使用Ogre進行編譯時遇到了同樣的問題。 我將/ usr / local / lib下的所有boost文件（.a和.so）復制到了/ usr / lib，它可以工作。
