Okay, so I'm trying to compile a simple hello world-program.

ocaml hello.ml

and

ocamlc hello.ml -o hello.exe

both work fine. When I do this:

ocamlopt hello.ml -o hello.exe

cl.exe says it can't find mspdb80.dll. I find the file in Microsoft Visual Studio 8\Common7\IDE, so I add it to my path, and try the above line again, and I get the error

LINK : fatal error LNK1181: cannot open input file 'advapi32.lib'

I find the file in Microsoft Visual Studio 8\VC\PlatformSDK\Lib, so I add that directory to my path, but the error remains! What am I doing wrong?

I didn't have one of those, and it didn't change anything, but I added the directory to the OCAMLLIB path, which already existed. Now, however, I get the error

>> Fatal error: cannot open Pervasives.cmiFatal error: exception Misc.Fatal_error

The directory where that file is is already in the OCAMLLIB variable, but also adding it to the regular PATH variable didn't make the error go away. What now?
