链接器找不到标准C库。

The linker can't find the standard C libraries.

您是否以正常方式安装Cygwin？ （这里有一个简单的指南： http://www.eecg.utoronto.ca/ 〜aamodt / ece242 / cygwin.html ）。

Did you install Cygwin in the normal way? (Here's a simple guide: http://www.eecg.utoronto.ca/~aamodt/ece242/cygwin.html).

您可以编译更简单的程序：

Have you been able to compile even simpler programs:

#include <stdio.h>

int main(int argc, char **argv) {
    printf("Found C library.\n");
}

如果不编译，你可能只是试图删除并重新安装Cygwin - 有东西坏了。

If that doesn't compile, you might just want to try removing and reinstalling Cygwin - something is broken.
