You partially are right, the issue is related to the application
internals but not to GTKD. I forgot that I launch the second
application inside. I recompiled both of the with
-L/SUBSYSTEM:windows -L/ENTRY:mainCRTStartup and that's it.
Thanks a lot everyone!

I've never used a module definition file for this. The
/subsystem:windows switch has always worked for me. When linking
with OPTLINK, that's all you need. When using the MS linker,
you'll need that along with the /ENTRY:mainCRTStartup. With
recent versions, if you don't have the MS tools installed, you'll
get the LLVM linker when using -m64 or -m43mscoff. If that's the
case, I don't know that it even supports changing the subsystem
or, if it does, what the syntax looks like. A cursory search
turns up nothing.

Both of the following command lines work for me.
With OPTLINK:
dmd -L/SUBSYSTEM:windows win.d
With the MS linker:
dmd -m64 -L/SUBSYSTEM:windows -L/ENTRY:mainCRTStartup win.d
user32.lib

Windows 7 x64. Prevent appearing of console with GUI application
Hello! I'm trying run my GUI application getting a console hidden. The application is on top of GTKD, compiled with dmd 2.081.1 in Windows 7 x64. I read a few threads on the forum and StackOverflow and I got that I need to add a module definition file [1] or to add -L/SUBSYSTEM:WINDOWS -L/ENTRY:mainCRTStartup options to compiler [2] or to add only /SUBSYSTEM:WINDOWS [3] or use a command getting console hidden [4]. Actually no one case works properly. The first one doesn't affect, the second "unbinds" appeared console giving ability to close it without closing the application, the third one raises a linker error about unresolved symbol WinMain, the fourth one hides a console but it does it with delay. Also, I tried to use `editbin /SUBSYSTEM:windows myapp.exe` but I it doesn't affect anything. Here is my dub.json [5] So... how prevent appearing of console on the startup of the application?
