I'm trying to compile a program to use gtkd, however, I don't know what options
I should pass to the d compiler. 

I'm using dmd to compile a test program. I'm using one of the example provided
on gtkd's dsource website: 

import gtk.MainWindow;
import gtk.Label;
import gtk.GtkD;

void main(char[][] args)
{
	GtkD.init(args);
	MainWindow win = new MainWindow("Hello World");
	win.setDefaultSize(200, 100);
	win.add(new Label("Hello World"));
	win.showAll();

	GtkD.main();
}

When I run dmd gtk_example.d, the compiler threw an error stating that it could
not find gtk/MainWindow.d. 

I did a search for the file and found that dsss had created a gtk directory
under /usr/local/include/d/, where /usr/local was the prefix that I used during
the build. I copied the program that I'm trying to compile to
/usr/local/include/d and tried to recompile it. This time It returned a number
of 'undefined reference' errors. For example:

gtk_example.o: (.data+0x30): undefined reference to  
'_D3gtk10MainWindow12__ModuleInfoZ'

It seems that I need to compile against a library. The instructions provided on
gtkd's dsource page say that I need to use gcc to handle linking, and gives the
following example: 

dmd myprog.d -c
gcc myprog.o -o myprog -lm -lpthread -ldl -lgtkd -lphobos

It seems that I'm missing the gtkd library. I'm guessing from ld's usage
conventions, that the library should be named libgtkd.a. I did a search for
this library and the closest thing that appeared was libDD-gtk.a. I tried
linking against this and it failed. At the moment I'm out of ideas.

Any help would be appreciated.

If you used dsss to download/install gtk then you should probably be 
using dsss to compile it:

dsss build myprog

With a simple one-line dsss.conf containing:

[myprog.d]

I created a new directory containing the example program and a dsss config
file. The config file contained the line that you gave me. When I executed dsss
build, the compiler threw a number of undefined reference errors. I'm pretty
sure that the program needs to be linked against a library to compile.
Unfortunately I don't names or locations of these libraries.

So you built and installed gtkd with dsss?
That should take care of most imports, but you still need to link against 
libdl
Put this in your source file:

version (build) {
     pragma(link, "dl");
}

that should hopefully fix the linker issue.

Gtkd uses dlopen() at startup to load all the associated libraries, so 
you dont have to have them available when you build. The only thing you 
need is the resuling libgtkD.a file (created from building gtkd)

Looks like the docs are pretty out of date.

compd is the best way to build gtkD stuff, as it's how the developers do 
stuff...

dmd YOURSOURCEFILE.d   -of/tmp/YOURCODENAME.o  -op  \
-Isrc:LOCATIONOFYOURCODE:/usr/src/gtkD/src -c   -g -I/usr/src/dmd/src/phobos

gcc  /tmp/YOURCODENAME.o -o YOURAPP -m32     -L.. -L. 
-L/usr/src/dui/gtkD  -lstdc++ -lphobos -lgtkd -ldl -g -m32 -lphobos 
-lpthread -lm


Should get you going.

Actually, we're working to get things working smoothly with dsss too.  
But part of the problem with dsss is that some users of it do not "follow 
the rules" or are confused about what rules they must follow (or they 
don't read the installation instructions); this tends to cause 
conflicts.  And then sometimes, it really is dsss' fault, or the config 
script it uses.  I use dsss pretty much exclusively now while developing 
gtkd.

dsss is really one of those "exclusive" tools.  That is, if you want it 
to work, you should be using in exclusively or you may end up with wierd 
configuration conflicts.

compd is still in there (gktd project) for those that use it... but it's 
not well documented, which is one reason that makes it less attractive to 
me.

llee, if you need some more help, you can post on the gtkd forums in 
dsource.  We can probably help you sort things out better there.

There should be a script somewhere named something like compdgtkD.sh

I think if you run that script it will make the library you need.
