hello,
now i don't know how to connect the eclipse cdt with my processor using architecture of altera..

Eclipse is an environment for coding, compiling and downloading. It is a generic environment and can be used for any processor. So, if you want to use it for your zpu processor, then you should prepare a library of drivers (= software programs that zpu will use to communicate with the peripherals in your specific project). I am sure they may already be available on zpu source sites. Else, you need to code drivers. Please also go through Eclipse documentation in this regard.

and the connection between the processor and led..

Once you are done with a software library of drivers, this is pretty simple. Your software library will also contain zpu drivers to communicate with led ports (actually LED is just one device from a family of devices which are driven by single ttl/otherwise lines). You will have several functions in your library (which you will have coded yourself) to control and monitor status of LEDs like LED_Read, LED_Write etc.

Though this is not very tough, it is important that you spend some time coding drivers. A deep perusal of NIOS drivers will be a good start as also the way libraries should be coded in Eclipse.
