Is there anyone out there using a mix of D with C/C++ and Fortran?

SCons goes to great lengths to be able to support almost arbitrary
combinations of C, C++, and Fortran -- where the compilers allow the
linker to link such combinations. Clealy mixing C and C++ or C and
Fortran are (relatively) straightforward, but mixing C++ and Fortran is
a problem. Adding DMD/GDC/LDC to this mix leads to a combinatorial issue
-- especially since the command line structures of dmd, gdc and ldc are
so different.

I am (slowly) arriving at the point of view that SCons support for D
should not be separate from the C, C++ and Fortran infrastructure, but
be an integral part of it -- it almost is already, so this is not as big
a deal as at first thought (possibly). On the other hand it is a big
deal because it involves solving some swept under the carpet issues...

Do you mean that between each other or compared to the C/C++/Fortan compilers? Both GDC (gdmd) and LDC (ldmd) ship with a wrapper script that emulates the DMD command lines. -- /Jacob Carlborg

 gdc normally follows the gcc command line conventions, which seems

 drop in replacement for dmd as well as being the D part of the GCC
 toolchain.

 Not sure about LDC, haven't really been able to use it yet.

Should be the same there as well. -- /Jacob Carlborg

Is it really required for GDC & LDC to emulate DMD's command line or those scripts serve as poor-man's crutches only?
