Compiling dll issue.

Aug 25, 2014

So i have been trying to follow the instructions on: http://wiki.dlang.org/Win32_DLLs_in_D but when i get to the step where i compile the dll dmd -ofmydll.dll -L/IMPLIB mydll.d dll.d mydll.def I get this output: OPTLINK (R) for Win32 Release 8.00.15 Copyright (C) Digital Mars 1989-2013 All rights reserved. http://www.digitalmars.com/ctg/optlink.html OPTLINK : Error 180: No Match Found for Export/ENTRY - : DllGetClassObject OPTLINK : Error 180: No Match Found for Export/ENTRY - : DllCanUnloadNow OPTLINK : Error 180: No Match Found for Export/ENTRY - : DllRegisterServer OPTLINK : Error 180: No Match Found for Export/ENTRY - : DllUnregisterServer OPTLINK : Error 81: Cannot EXPORT : DllCanUnloadNow OPTLINK : Error 81: Cannot EXPORT : DllGetClassObject OPTLINK : Error 81: Cannot EXPORT : DllRegisterServer OPTLINK : Error 81: Cannot EXPORT : DllUnregisterServer --- errorlevel 8 Not, very pretty. Do I have something not setup right? Im using the latest DMD as of 8/25/2014. 2.066.0 Any Ideas?

So, I figured it out! I used the wrong example for mydll.def.

---------------------------------------------
LIBRARY         MYDLL
DESCRIPTION     'My DLL written in D'

EXETYPE		NT
CODE            PRELOAD DISCARDABLE
DATA            WRITE

EXPORTS
		DllGetClassObject       @2
		DllCanUnloadNow         @3
		DllRegisterServer       @4
		DllUnregisterServer     @5
----------------------------------------------
The above will cause errors: even though it makes you think that it should be mydll.def it is not.

----------------------------------------------
LIBRARY "mydll.dll"
EXETYPE NT
SUBSYSTEM WINDOWS
CODE SHARED EXECUTE
DATA WRITE
----------------------------------------------
The above is the correct .def contents

Thanks all!

If you don't use the extern(C) foreign function interface then the name won't match to the export name as written in the source (in the binary you'll get the bytecount of all the param size with a @ before). si you need to create a name table for optlink (http://www.digitalmars.com/ctg/ctgDefFiles.html) (http://www.digitalmars.com/archives/cplusplus/4029.html)
