conditional custom build step

[CambridgeGuy]

Hi.

I have a few assembly (NASM) files that are part of a C++ project. I use custom build commands to compile these files and it works fine.

I am trying to find a way to only compile these files when a certain preprocessor definition exists. For example, in the C code where the routines from the assembly files are used, I use "#ifdef USE_ASM" to only call those routines when USE_ASM is defined. Is there any way I can do something similar in the custom build command?

The only alternative I have been able to come up with so far is to create separate Project Configurations for using the assembly files, but this makes the project more complicated than I would like.

Any suggestions?

Is this VS6, VS2002.net, VS2003.net or VS2005.net? The configuration is different depending on which version you're using.

Sorry, I forgot to include that info.

I'm using MSVC6. But if there are solutions to this problem that use one of the newer versions, please let me know. I would consider switching.

Are you running on a platform that supports WSH? (eg 98/ME/2000/XP)

Yes, I am.
