我是Cygwin,Windows和C ++的新手,所以请耐心等待。
这是C ++程序(try.cpp)我试图使用Cygwin编译。
#include<iostream>
using namepsace std;
int main(void) {
cout<<"Trying out CPP"<<endl;
return 0;
}
这是我正在使用的Cygwin版本(在cygwin终端上使用uname -r
获得):1.7.17(0.262/5/3)
这是我用来编译程序的命令:
g++ try.cpp
以下是我得到的错误:
$ g++ try.cpp
try.cpp:2: error: expected nested-name-specifier before "namepsace"
try.cpp:2: error: `namepsace' has not been declared
try.cpp:2: error: expected `;' before "std"
try.cpp:2: error: expected constructor, destructor, or type conversion before ';' token
try.cpp: In function `int main()':
try.cpp:5: error: `cout' undeclared (first use this function)
try.cpp:5: error: (Each undeclared identifier is reported only once for each function it appears in.)
try.cpp:5: error: `endl' undeclared (first use this function)
FWIW,这是我做g++ -v
时得到的结果(我猜想计算机上安装的g ++版本)“

我做错了什么?
答案 0 :(得分:3)
您拼错/错误输入namespace
为namepsace
。
