I'm trying to get d++ to work on Windows 10/64-bit machine but it

foo.dpp from here

went to run:

 d++ foo.dpp c.o
I got the error:

dmd version:

gcc version 6.3.0 (MinGW.org GCC-6.3.0-1)
d++ the least one, build from sources my OS is windows 10/64-bit. What am I missing?

I have never used dpp, but the github page says you should use LDC, not DMD. And I could not find anything implying gcc is supported.

what the docs says is about to use ldc2 to build from source code, which I did. That failed dmd call is done by d++ internally.

DMD expects .obj for Windows. So you'll probably have to use the MS compiler or clang to emit an MSVC-compatible object file, and then use either -m32mscoff or -m64 for DMD.

that worked, thanks! i used MS C compiler to get the object file
 cl /arch:IA32 /c c.c
then:
 d++ -m32mscoff foo.dpp c.obj
worked fine
