我收到此错误消息。我试图用 CYGWIN 做正确的事情，我做错了什么吗？你需要更多信息？

"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf
make[1]: Entering directory `/cygdrive/c/Users/Liam/Documents/NetBeansProjects/playing with c'
cygwin warning:

  Preferred POSIX equivalent is: build/Debug/Cygwin_4.x-Windows/hello/.d
  CYGWIN environment variable option "nodosfilewarning" turns off this warning.
  Consult the user's guide for more details about POSIX paths:

您已经在多个地方定义了 main 方法：main.c:14 和 hello world.c:3。

一个程序只能有 1 个 main 方法。

从项目中删除这些文件之一，或删除主要方法定义之一。
