在cygwin上编译套接字客户端和服务器 [英] compiling socket client and server on cygwin
问题描述
您好。
我正在尝试在
windows上编译linux套接字服务器和cygwin中的客户端。 g ++版本是3.3.1。来源是从这个
位置获得的：
http://www.linuxgazette.com/issue74/tougher.html
ServerSoccket.cpp显然编译正常。 Socket.cpp有问题。这是
我的输出：
$ make -f Makefile.txt
g ++ -c -o ServerSocket.o ServerSocket.cpp
g ++ -c -o Socket.o Socket.cpp
Socket.cpp：在成员函数`int Socket :: recv（std :: string&）中const''：
Socket.cpp：135：错误：`cout''未命名在命名空间`std''
Socket.cpp：在成员函数中`bool Socket： ：connect（std :: basic_string< char，
std :: char_traits< char>，std :: allocator< char>>，int）''：
Socket .cpp：158：错误：`inet_pton''未声明（首先使用此函数）
Socket.cpp：158：错误:(每个未声明的标识符只报告一次
它出现在每个函数中。）
make：*** [Socket.o]错误1
cout如何在C ++中未声明？不是基本的基础之一吗？
请帮助，
Eugene。

你好。
我试图在
windows上的cygwin中编译一个linux套接字服务器和一个客户端。 g ++版本是3.3.1。来源是从这个位置获得的：
http://www.linuxgazette.com/issue74/tougher.html
ServerSoccket.cpp显然编译好了。 Socket.cpp有问题。这是我的输出：
make -f Makefile.txt
g ++ -c -o ServerSocket.o ServerSocket。 cpp
gocket -c -o Socket.o Socket.cpp
Socket.cpp：在成员函数`int Socket :: recv（std :: string&）const''：
Socket。 cpp：135：错误：`cout''未命名在命名空间`std''
Socket.cpp：在成员函数`bool
Socket :: connect（std :: basic_string< char，std :: char_traits< ; char> ;,std :: allocator< char>>，int）''：
Socket.cpp：158：错误：`inet_pton''未声明（首先使用此函数）
Socket.cpp： 158：错误:(每个未声明的标识符只报告一次它出现的每个函数
。）
make：*** [Socket.o]错误1
怎么能cout在C ++中未声明？这不是基本的基础之一吗？
请帮忙，
查看代码，作者未能包括< ;&的iostream GT;这是定义std :: cout的
头文件。包括< iostream>在Socket.cpp和你
应该没问题。

Hello.
I am trying to compile a linux socket server and a client in cygwin on
windows. The g++ version is 3.3.1. The source was obtained from this
location:
http://www.linuxgazette.com/issue74/tougher.html
ServerSoccket.cpp apparently compiles OK. Socket.cpp has a problem. Here''s
my output:
$ make -f Makefile.txt
g++ -c -o ServerSocket.o ServerSocket.cpp
g++ -c -o Socket.o Socket.cpp
Socket.cpp: In member function `int Socket::recv(std::string&) const'':
Socket.cpp:135: error: `cout'' undeclared in namespace `std''
Socket.cpp: In member function `bool Socket::connect(std::basic_string<char,
std::char_traits<char>, std::allocator<char> >, int)'':
Socket.cpp:158: error: `inet_pton'' undeclared (first use this function)
Socket.cpp:158: error: (Each undeclared identifier is reported only once for
each function it appears in.)
make: *** [Socket.o] Error 1
How can cout be undeclared in C++? Isnt that one of the basic basics?
Please help,
Eugene.

Look at the code, the author has failed to include <iostream> which is the
header file that defined std::cout. Include <iostream> in Socket.cpp and you
should be OK.
