Hi
I have an existing C shared library that I am trying to link to a
D shared library. The D shared library at present only has a
binding (extern (C)) definition, nothing else.
When I try to create the shared library using the DMD command
line I get link errors.
Platform is Windows 10 64-bit.
The command I am using is:
dmd -m64 -shared -v -L/LIBPATH:c:\ravi\lib -Lravimatrix.lib
source\matrix.d
Partial output from DMD follows:
binary C:\D\dmd2\windows\bin\dmd.exe
