cygwin和eclipse CDT安装好了后不能使用cygwin编译

先安装了cygwin

在path中加入 cygwinbin

安装eclipse CDT 7.0

打开eclipse -> new project

创建hello world 后

使用build报如下问题

**** Build of configuration Default for project test ****

****  WARNING: The "Default" Configuration may not build  ****
****  because it uses the "cdt.managedbuild.toolchain.gnu.cygwin.base"  ****
****  tool-chain that is unsupported on this system.  ****

****  Attempting to build...  ****

(Cannot run program "make": Launching failed) 注：在windows的命令行下可用

请问如何配置？
