passing code through the preprocessor only

[semblance]

Hi, I'm trying to convert a large Visual Studio 6 C++ project to Java. I could find a converter tool, but I'd rather do it by hand as an exercise to understand the code.

My question is whether there is a way to pass the code through the Visual C++ compiler such that it *only* interprets the preprocessor directives. There are quite a few #defines and #ifdef directives around, and I'm not certain which are used and which are ignored.

See /P (and /C) compiler directive(s).
For example, preprocess file.cpp to file.i in cmd line:

cl /P file.cpp

You may set this directive in IDE too (see Project Setting panel).

Cool, thanks. Exactly what I needed.
