what 
I'm getting:

$ gdc -fshared -Wl,-soname,libfoo.so -o libfoo.so foo.o
/usr/bin/ld: unknown flag: -soname
collect2: ld returned 1 exit status

That's on Mac OS X. How about also setting up a wiki page so it's easy to find?

I haven't created a shared library with GDC, but the shared (.so) files 
on other platforms are known as either dynamiclib or bundle on Mac OS X.
Dynamic libraries are for linking to and bundles for loading at runtime,
for instance program plugins and modules for Perl or Python are bundles.

Using -soname should be equivalent to -install_name on Mac OS X. See:
http://developer.apple.com/documentation/developertools/gcc-4.0.1/gcc/Darwin-Options.html
$ gcc -dynamiclib -Wl,-install_name,libfoo.dylib -o libfoo.dylib foo.o
But my GDC says cc1d: error: unrecognized command line option "-fshared"

Weird...

/usr/bin/ld: -i argument: nstall_name must have a ':' between its symbol names

Which compiler are you using ? (I'm using the regular Mac OS X 10.4 one)

OK, if you are using the FSF version of GCC it probably doesn't know 
about the various linker flags for Darwin - those are Apple specials.

$ gdc -v
...
gcc version 4.0.1 (Apple Computer, Inc. build 5363) (gdc 0.23, using dmd 
1.007)

$ gcc -v
...
gcc version 4.0.1 (Apple Computer, Inc. build 5367)

Apple hasn't released the source codes to Xcode 2.4.1 just yet, that's
why the difference in the build numbers (gcc-5363 was from Xcode 2.4)

I downloaded Apple's version:

gcc version 4.0.1 (Apple Computer, Inc. build 5341) (gdc 0.23, using dmd 1.007)

But I get the same thing:

/usr/bin/ld: -i argument: nstall_name must have a ':' between its symbol names

And I guess that makes sense because it's ld that's failing, not gcc.

$ /usr/bin/ld -v
Apple Computer, Inc. version cctools-590.18.obj~10
