编译netbeans中的cpp代码会产生错误,如何解决呢？

Question

我使用netbeans与MinGW和MYSY make/debugger,但当我编译一个基本的cpp代码并运行它产生两个erorrs

这是运行的代码和输出![alt text] [1]框

#include <iostream>
void main()
{
  cout << "Hello World!" << endl;  
  cout << "Welcome to C++ Programming" << endl;
}

输出是

/usr/bin/make -f nbproject/Makefile-Debug.mk SUBPROJECTS= .build-conf
make[1]: Entering directory `/d/Users/Home/Documents/NetBeansProjects/newApp'
/usr/bin/make  -f nbproject/Makefile-Debug.mk dist/Debug/MinGW-Windows/newapp.exe
make[2]: Entering directory `/d/Users/Home/Documents/NetBeansProjects/newApp'
mkdir -p dist/Debug/MinGW-Windows
g++.exe     -o dist/Debug/MinGW-Windows/newapp build/Debug/MinGW-Windows/newmain.o build/Debug/MinGW-Windows/newfile.o build/Debug/MinGW-Windows/main.o  
build/Debug/MinGW-Windows/newfile.o: In function `main':

collect2: ld returned 1 exit status

make[2]: *** [dist/Debug/MinGW-Windows/newapp.exe] Error 1
make[2]: Leaving directory `/d/Users/Home/Documents/NetBeansProjects/newApp'

make[1]: Leaving directory `/d/Users/Home/Documents/NetBeansProjects/newApp'
make: *** [.build-impl] Error 2
BUILD FAILED (exit value 2, total time: 1s)

我怎么能解决这个问题？

Answer 1

我在这里可以看到三件事,前两部分已由Xavier和jwismar指出,但要巩固:

1. 两者D:/Users/Home/Documents/NetBeansProjects/newApp/newfile.cpp并D:/Users/Home/Documents/NetBeansProjects/newApp/main.cpp定义一个main().您需要从项目中删除其中一个.

2. 你需要using std::cout和using std::endl.

3. main()应该总是返回一个int.
