BCB5 Where is WIN32 defined ?

I have the following line of code in one of my Borland C++ Builder 5 projects CPP modules

#define WIN32

This produces an error "Redefinition if WIN32 is not Identical"

I am not able to find any other re-definition by searching All Files in the project.

Can anyone advise me as to where WIN32 is originally defined ?

Taks a look at your project settings, it is likely that this is passed to the compiler as a command line option.

I am running the compiler from the IDE, not the command line.

jkr

Yes, I presumed that. That's why I suggested the settings.

There are no references to WIN32 under any of the tabs in Project|Options ??

jkr

Is there anything like "preprocessor definitions"?

Roger Alcindor

ASKER

No, there is no mention of preprocessors.

I have devised a workaround however, I preceed the #define WIN32 with the line #undef WIN32

Possibly not the best solution but I have spent too much time on this issue already.

jkr

Well, instead uf an #undef, you could change that to

#ifndef WIN32
#define WIN32
#endif

you better remove the #define WIN32 statement in your code. such a basic macro never is defined in individual code but either in the compiler or project settings or in very basic header files of the libraries used. in the latter case it is done like jkr has shown cause a redefinition of that fundamental macro won't make a sense for any normal environment.

The reason that I included #define WIN32 in my code was due to the fact that a third party API (supplied with PicoScope, the USB oscilloscope) would not work with my compiler without it.

By the way, changing #define WIN32 to #define WIN32 1 does not fix the problem either.

The compiler isn't clever enough to realise you haven't actually redefined WIN32 with "#define WIN32 1" then. As sara says - #include <windef.h> should sort this out for you.

Thanks for your help, I adopted Sara'smost recent comment and it fixed the problem.
