Linking C++ standard library works with GDC... but not DMD. (Linux)

[TheGag96 via Digitalmars-d-learn]

Hi, I've got this project that requires me to link into a C++
backend. It works just fine when using GDC:

gdc *.d [client libraries]

However, this command using DMD does not work:

dmd -L-lstdc++ *.d [client libraries]

I still get errors involving the standard library not being added
like:

/usr/include/c++/4.8/iostream:74: undefine reference to
`std::ios_base::Init::Init()'
(etc.)

What do I need to do to make this work? Thanks.
