Hi everyone!

I need sample to make 64-bit dll in D with C interface.
I tried to use "mydll" sample in C:\D\dmd2\samples\d\mydll\, but it fails:
----------
C:\D\dmd2\samples\d\mydll>..\..\..\windows\bin\dmd -m64 -ofmydll.dll -L/IMPLIB mydll.d dll.d mydll.def
LINK : fatal error LNK1146: no argument for "/IMPLIB" parameter
Error: linker exited with status 1146

C:\D\dmd2\samples\d\mydll>..\..\..\windows\bin\dmd -m64 test.d mydll.lib
LINK : fatal error LNK1104: не удается открыть файл "mydll.lib"
Error: linker exited with status 1104
----------

32-bit version (which is usless for me) gives another error messages:
----------
C:\D\dmd2\samples\d\mydll>build.bat
C:\D\dmd2\samples\d\mydll>..\..\..\windows\bin\dmd -ofmydll.dll -L/IMPLIB mydll.d dll.d mydll.def
C:\D\dmd2\samples\d\mydll>..\..\..\windows\bin\dmd test.d mydll.lib

In earlier version 2.073.3 of DMD compiler 32-bit version of "mydll" builds successfully, but 64-bit get the same error messages as above. I use 64-bit path settings. DMD compiler version 2.079.0, Windows 7 Pro (6.1, build 7601: Service Pack 1).

-m64 uses the MS linker, not Optlink. You don't need /IMPLIB for that unless you intend to change the default name for the generated import library. This should build a 64-bit DLL for you:

dmd -m64 -ofmydll.dll -L/DLL mydll.d dll.d

And actually, the -of parameter is superfluous in this case. The DLL will pick get the name of the first source module by default.

Thank you very much! Now it compiles successfully.
