On windows, optlink is used by dmd to link binaries. optlink is the linker for dmc. Since, you need compatible linkers for both the D and C code if you want them to link together, you use dmc for your C code.

On Linux, gcc is used to link by dmd to link binaries. So, the C code needs to be linked by gcc. And since it pretty much already all is, you don't have to worry about it. The situtation is much better than on Windows where there you're more likely to be using Microsoft's compiler than dmc, and you have to adjust what your doing to use dmc. On Linux, it should just work (as long you're dealing with 32-bit libraries anyway; that can be a bit of a problem on 64-bit machines, since the 64-bit port for dmd isn't complete yet, but generally all you have to do is make sure that you have the 32-bit versions installed, and you should be fine).

Thats good news. I stick to 32 bit as 64 bit still seems to be a hassle for drivers etc. Thanks very much.
