I was trying to check out windbg with a project I am working on. The program currently consists of two D files (main.d, Application.d) and three Derelict3 import libs (DerelictUtil, DerelictSDL2, DerelictGL3). Without debug info, the following console command runs fine;

---

dmd main.d Application.d DerelictUtil.lib DerelictSDL2.lib DerelictGL3.lib

---

However, no matter where I put either the -g or -gc switches, Optlink complains with 'Error 118: Filename Expected', and proceeds to spit out my PATH environment variable. I tried with just a 'Hello World' program that only imports 'std.stdio', and I get the same problem.

Could anyone explain to me what the problem is? I have the feeling that there is something I need to do to set up Optlink, however I installed from the Windows binary on dlang.org. If it matters, I'm running Win7

OK, so it's a bug rather than a failure on my part? That's comforting, if a little problematic.

Likely. What does your PATH variable look like?

Horrific. It's full of paths to sub-directories of "C:\Program Files\". I've found that if I run "set PATH=C:\D\dmd2\windows\bin" before compiling, it works fine. If it usually takes time for this, I'll just set up a cmd shell with this reduced PATH envvar, I think.
