GNUstep Project Center Build problem

[周承康]

Dear GNUstep:

I'm a new comer of GNUstep. Once I install the GNUstep (include Project Center & Gorm) 

and input a sample code, I'm now faced a problem when I press "Build" button.

error message : 

5: /common.make : no such file or directory

50: /aggregate.make : no such file or directory

51: /application.make : no such file or directory

GNUmakefile:5: /common.make : no such file or directory

GNUmakefile:50: /aggregate.make : no such file or directory

GNUmakefile:51: /application.make : no such file or directory

make: *** Norule to make target '/application.make'. Stop.

===Build terminated! ===

and after I survey from google search, I still can't get any helpful solution.

So I have to get some advise from GNUstep. thanks.

Best regards.

Rico.
