digitalmars.D.learn - Trouble with LDC2 and definition file to hide console?

reply spikespaz <spikespaz outlook.com> writes:
I am trying to add a *.def file to my program to hide the console 
window on launch, as it doesn't need to display anything to 
function. It is a Windows only application.

I saw at this post 
(https://forum.dlang.org/post/ilj5vn$ef4$1 digitalmars.com) that 
I could either use a linker flag, -L/exet:nt/su:windows, or add a 
module definition file. I decided on the definition file.

EXETYPE NT
SUBSYSTEM WINDOWS

I have this file named deflector.def, and I compile with the 
command as follows.

ldc2 source/* -of="build/SearchDeflector-x86.exe" -O3 -ffast-math 
-release


All of my source code and the *.def file is in the source/ 
directory. I am not using DUB. The issue when compiling says that 
those two definitions(?) aren't supported for my target. That 
doesn't make sense because I am using the MSVC linker with LDC2.

source\deflector.def(1) : warning LNK4017: EXETYPE statement not 
supported for the target platform; ignored
source\deflector.def(2) : warning LNK4017: SUBSYSTEM statement 
not supported for the target platform; ignored

Any help would be appreciated.

I would also like to know how to add a PNG or ICO file to my 
compiled executable. I have icons in the resolutions of 16, 32, 
64, 128, 256. Currently I'm adding them in using GitHub's RCEDIT 
tool (https://github.com/electron/rcedit) but I would like a more 
proper way.

Also adding that the linker flag I have stated above also is 
ignored by the linker.

LINK : warning LNK4044: unrecognized option 
'/exet:nt/su:windows'; ignored

That is for Optlink not for MSVC link which ldc uses.

Exactly. For LDC, just rename your main() to WinMain().

Or alternatively, `-L/SUBSYSTEM:WINDOWS -L/ENTRY:mainCRTStartup` 
in the LDC cmdline.
