fatal error C1017: invalid integer constant expression

Question

Hi,

I have got a statement in my code:

#if DEBUG==0

this works fine in gnu g++ but it fails in VC++. Can anyone explain what is wrong with this.

I have already read msdn help on this topic. so, if debug is defined as 1 then this is false i.e.0, so it should work and similarly if debug=0

Can anyone suggest how to correct this. My code has to be compiled both in linux and win.

Thanks

Leave it like:

#if DEBUG

Though I should add that typically one checks if DEBUG is defined, not if it is 1. To declare you simply say:

#define DEBUG

Check if it is not defined with:

#ifndef DEBUG
