Hello. I am trying to make a wrapper to use the DarkGDK 3d

it to successfully compile however the resulting exe

command in WinMain
is writeln which doesnt show up.
It may be the case that you need to call rt_init(); at first
line of
WinMain. Every time I see WinMain problems it boils down to D
runtime not
setup properly.
I agree. Take a look at http://dlang.org/windows.html
Working from that, I was able to get your app to begin to
start up.
The other trick is that when you structure your main this way,
stdout/stderr/stdin don't seem to be set up for you (at least,
not
with MinGW GDC). I added this:
stdout = File("test.txt", "w");
and now test.txt contains this:
%sCreating Swindow
%sInitializing DarkGDK
It's still crashing, but it's getting significantly farther. I
haven't
dug enough to figure out what's going on now.
Actually, it's not crashing, it's failing to initialize DarkGDK
and
bailing nicely. Looks like it's probably because the DarkGDK
DLL is 32
bit and I'm building a 64 bit executable.
If I switch to a 32 bit executable and add a stdout.flush()
after
every writeln, I get this:
%sCreating Swindow
%sInitializing DarkGDK
%sStarting the window
%sHanind the window to DarkGDK
Unfortunately, I can't debug the crash for some reason. I'll
have to
ping the MinGW GDC folks about it.
The code looks like this: http://pastebin.com/i5A3PFTt
My GDC build.bat looks like this: http://pastebin.com/PW30V3q4
Great, thanks for the help so far. I have altered some of the
code for main.d and simplewindow.d to incorporate these tips.
Mainly i have offloaded WinMain to simpleWindow.d and made it
call GDKmain which is my new main(post WinMain) function in the
main.d i had wanted to do this originally as i didn't like making
the end-user have to have a WinMain with all these args that they
don't need for this engine and the need to export windows. There
may be issues with doing this later on but for the moment i like
it this way except for the fact that showWindow in GDKmain needs
the nCmdShow from WinMain so i have to pass that along to it
still.
I have also reordered the way things are called in main.d so that
things make more sense, so it tries to initialize the dll (and
fails) then starts creating the window, you don't want a window
just sitting there blank and non responsive while the dll
initializes so thats what i have done.
Yes the dll is 32bit, i am just using plain dmd and haven't had
any problems as i believe its just doing 32bit as i wanted it to.
I did actually have the runtime initialization in the
Swindow.start but i guess it has to be a part of WinMain to work.
I just replaced the file at the previous download link in the OP
so if you re-download from there you get the new version with the
adjustments. also i added kernel32.lib to the build as
MonoDevelop seems to do that so i thought i should too.
Thanks for the help so far guys, cant wait to get this to work!
