digitalmars.D - how to "include" the module file like C ?

Hi, I can auto index the module file use gcc,
but in D I must append the module file path to dmd args,
if I don't, dmd will give me an error like:
main.o: In function `_Dmain':
main.d:(.text._Dmain+0x15): undefined reference to `_D3lib1ai'
main.d:(.text._Dmain+0x2d): undefined reference to `_D3lib1ai'
collect2: ld returned 1 exit status
--- errorlevel 1

Here is the example:
//main.c
#include <stdio.h>
#include "lib.c"
int main(int argc, char** argv){
	printf("%d\n", a);
	a = 10;
	return 0;
}

//lib.c
int a = 1;

[pass] gcc main.c

//main.d
import std.stdio;
import lib;
int main(string[] args){
	writeln(lib.a);
	lib.a = 10;
	return 0;
}

//lib.d
int a = 1;

[pass] dmd main.d lib.d
[failed] dmd main.d
[failed] dmd main.d -inline
[failed] dmd main.d -I./
[failed] dmd main.d -I/full/path/

That mean I can't use geany to do the one key build when import 
the modules from file,
anybody known how to "include" the module file in D ?
Please teach me, thanks very much.

You can include a file as text using import("filename"), and you can convert it to code using mixin(string) mixin(import("lib.d")); will work for you example. *BUT*... You are completely breaking the module system and working against the language rather than with it. I recommend you use the tool rdmd: "rdmd main" will pick up dependencies and add them to dmds command line.

Rdmd works perfect, I just need replace linker=dmd -w -of"%e" "%f" to linker=rdmd --build-only -w -of"%e" "%f" in filetypes.d for geany then all things will be good. Thank you very much !
