Linking libraries that are written in C++ with a C interface

[Gerry via Digitalmars-d]

Hello All,

I'm trying to link a library that is written in C++ that provides 
a C interface. Unfortunately the lib is proprietary, so I can't 
include the code. I'm getting undefined references to new and 
delete operators etc.  This links fine with gcc. I'm using the 
following command line to build.

dmd test.d file1.d file2.d -L/path/to/lib/lib.a

Is this the write way to link a static library? I was actually 
using ldc, but couldn't get that to work at all.

Thanks,
-G
