it's ok ,but where is the file for config?
---------------------get another error:

I'm not known the GDC config file ,and maybe I use the error 
build .
Who can help me?
  thank you.

  thank you.
About the first error ("...module wiringPi is in file 'wiringPi.d' which cannot be read...") - are you sure that the dfiles are in "./wiringPi/WiringPi/"? The compiler reports that it can't find them there. You can try copying the WiringPi dfiles in the same folder as "my.d". About the second error - you need to verify that aa.so actually has those symbols that the linker reports as "undefined reference". You can do this with readlelf or nm. For more info see here:http://stackoverflow.com/questions/1237575/how-do-i-find-out-what-all-symbols-are-exported-from-a-shared-object

Thank you,but can you tell me that what is right way to use GDC on linux,such as d refer a c lib. for eacample: a.d refer x.h x.c how do you build it by GDC? what's your steps? How to config the GDC for the thirty c lib and d files. Thank you,waiting for your answer.
