c - 我无法构建 HELLO, WORLD 程序？

Question

我是学习 C 的新手，我在 Windows 上(我想在 Windows 上学习)。

我已经在 cygwin 上安装了 GCC，并且我正在使用 NetBeans IDE。

来源:

#include <stdio.h>

main()
{
    printf("Hello, world!\n");
    return 0;
}

我在构建上述代码时遇到了这个错误:

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
make[1]: Entering directory `/cygdrive/g/VS Projects/Hello World'
"/usr/bin/make"  -f nbproject/Makefile-Debug.mk dist/Debug/Cygwin_4.x-Windows/hello_world.exe

有什么简单的方法可以在 Windows 上学习 C 吗？(visual studio 给我错误，似乎主要是针对 c++，所以这不是一个选项)

问题可能出在您的 gcc 或您的 NetBeans 配置上

这里一切正常

// helloworld.c
#include <stdio.h>

main()
{
    printf("Hello, world!\n");
    return 0;
}

编译成myprog

$ gcc helloworld.c -o myprog

运行它

$ ./myprog
# => Hello, world!
