digitalmars.D - SCons, Linking and D

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.

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

gdc normally follows the gcc command line conventions, which seems
reasonable as it is intended to be part of GCC :-) gdc happens to also
offer gdmd which is an adaptor between the dmd command line conventions
and gdc activity. This seems fine to me since it means gdc can act as a
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.
