I download the 'wiringPi' from http://wiringPi.com,convert the

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.
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

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 third part c libaries and d
files,such as PATH.
Thank you,waiting for your answer.
