Hello,

I am trying to set MAC_OS_X_VERSION_MIN_REQUIRED in my app, like so:

#define MAC_OS_X_VERSION_MIN_REQUIRED MAC_OS_X_VERSION_10_3

However, CW is giving me an error, saying

Error : macro 'MAC_OS_X_VERSION_MIN_REQUIRED' redefined

Error : (location of previous definition)
#define MAC_OS_X_VERSION_MIN_REQUIRED MAC_OS_X_VERSION_10_1

How can I define this so that I don't get an error? I tried putting in my
Preprocessor panel text, but that also gave me an error.

Thanks!
Bint

Where is it previously defined? I define mine in my .pch prefix file.

I don't know. It just says this:

Error : (location of previous definition)
#define MAC_OS_X_VERSION_MIN_REQUIRED MAC_OS_X_VERSION_10_1

Then, in /usr/include/AvailabilityMacros.h has this:

/*
* If min OS not specified, assume 10.1
* Note: gcc driver may set _ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED_
based on MACOSX_DEPLOYMENT_TARGET environment variable
*/
#ifndef MAC_OS_X_VERSION_MIN_REQUIRED
#ifdef __ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
#define MAC_OS_X_VERSION_MIN_REQUIRED
__ENVIRONMENT_MAC_OS_X_VERSION_MIN_REQUIRED__
#else
#if __ppc64__ || __i386__
#define MAC_OS_X_VERSION_MIN_REQUIRED MAC_OS_X_VERSION_10_4
#else
#define MAC_OS_X_VERSION_MIN_REQUIRED MAC_OS_X_VERSION_10_1
#endif
#endif
#endif

Well, you could always use #undef as a workaround.

Really? I didn't know about that.

You need to put your macro before the OS default, which means that it needs to
go into C/C++ preprocessor settings of your target, not in your source.
