1. Download gtkD 1.3 from gtkd
2. unzip
3. run make to run the GNUmakefile in the base directory.
4. su to root
5. make install copies include and lib files under /usr/local/.

libraries:

libgtkd.a
libgtkdgl.a
libgtkdsv.a

Test it out…

1. cd to gtkD/demos/gtk
2. try to compile HelloWorld.d.

First attempt was to do

ldc HelloWorld.d

That resulted in a linking error:

After a lot of searching, I found a note is post that alluded to a solution - link manually with gcc, instead of letting ldc do the linking:

ldc -c HelloWorld.d
gcc HelloWorld.o -o HelloWorld -lm -lpthread -ldl -lgtkd -ltango-base-ldc -ltango-user-ldc -v
Using built-in specs.

And that leaves me with an executable that runs.

Other information I found, seemed to indicate that I needed to use dsss to build. That went nowhere because there doesn’t appear to be any way to install dsss with/to-work-with ldc (only dmd and gdc).

At this point my /usr/local/bin/ldc.conf is… “/usr/local/include/d” contains the header files for gtk.

default:
{
    // 'switches' holds array of string that are appends to the command line
    // arguments before they are parsed.
    switches = [
        "-I/usr/local/include",
        "-I/usr/local/include/tango",
        "-I/usr/local/include/d",
        "-L-L/usr/local/lib",
        "-L-ltango-user-ldc",
        "-d-version=Tango",
        "-defaultlib=tango-base-ldc",
        "-debuglib=tango-base-ldc"
    ];
};

It seems as though ldc should be able to be configured to link, since I think it uses gcc to do its linking. Seems there is something about gtkD needing to be able to load gtk libraries dynamically.
