Now I build a project for ARM linux on ubuntu 15.04 ,but build error.
I download the 'wiringPi' from http://wiringPi.com,convert the *.h to *.d.then build the 'aa.so' file:
#! /bin/sh
dfiles="max31855.d max5322.d mcp23008.d mcp23016.d mcp23016reg.d mcp23017.d mcp23s08.d mcp23s17.d mcp23x08.d mcp23x0817.d mcp3002.d mcp3004.d mcp3422.d mcp4802.d pcf8574.d pcf8591.d sn3218.d softPwm.d softServo.d softTone.d sr595.d wiringPi.d wiringPiI2C.d wiringPiSPI.d wiringSerial.d wiringShift.d wpiExtensions.d"

 /opt/arm-unknown-linux-gnueabihf/bin/arm-linux-gnueabihf-gdc  -o aa.so $ofiels $dfiles  -shared
---------------------------------------my.d
import wiringPi;
import std.stdio;

void main()
{
	writeln("start");
	wiringPiSetup();
	pinMode(0,OUTPUT);
	while(1)
	{
		digitalWrite(0,HIGH);
		delay(500);
		digitalWrite(0,LOW);
		delay(500);
	}
return;
}
-------------------------------------build the my execute file
/opt/arm-unknown-linux-gnueabihf/bin/arm-linux-gnueabihf-gdc  -o my  my.d aa.so -I./wiringPi/WiringPi/

---------------------now get the error:
my.d:1:8: error: module wiringPi is in file 'wiringPi.d' which cannot be read
 import wiringPi;
        ^
import path[0] = /opt/arm-unknown-linux-gnueabihf/lib/gcc/arm-unknown-linux-gnueabihf/5.2.0/include/d
---------------------I copy the *.d to /opt/arm-unknown-linux-gnueabihf/lib/gcc/arm-unknown-linux-gnueabihf/5.2.0/include/d
it's ok ,but where is the file for config?
---------------------get another error:
/tmp/cc7M1B9I.o: In function `_Dmain':
my.d:(.text+0x60): undefined reference to `wiringPiSetup'
my.d:(.text+0x6c): undefined reference to `pinMode'

my.d:(.text+0x98): undefined reference to `digitalWrite'
my.d:(.text+0xa0): undefined reference to `delay'
collect2: error: ld returned 1 exit status
---------------------------------end

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 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.

 How to config the GDC for the third part c libaries and d files,such as PATH.

 Thank you,waiting for your answer.

 I've gotten the answer: use the difference 'gcc' for c code.
