OSX Undefined Sybols error

SDL Development

Hi there,

I’m trying to compile in SDL for the first time and I keep getting:

Undefined symbols: _CGMainDisplayID referenced from SDL expected to be
defined in Carbon

What can I do to fix this error?

Thanx

First you should mention which version of Mac OS X you’re using, which
version of SDL you’re attempting to compile, and which toolchain you’re
attempting to compile it with (autoconf, Project Builder, Xcode,
CodeWarrior).

Sorry about that. :stuck_out_tongue:

I’m on Mac Os X 10.1.5
Running SDL 1.2.8
on Project Builder 2.0

It’s a strange error that I keep getting when I try to compile code.

Any help is welcome. Thanx!

CGMainDisplayID() is not supported on Mac OS X 10.1. SDL currently
uses kCGDirectMainDisplay in SDL_QuartzVideo.m, which is a macro that
calls CGMainDisplayID(). This code would need to be changed to use
CGGetActiveDisplayList(…) instead if it were to become Mac OS X 10.1
compatible. Obviously nobody else cares about Mac OS X 10.1, so you’d
have to actively make sure that SDL CVS remains 10.1 compatible or else
it probably won’t be.

I’d recommend that you simply upgrade to a newer version of Mac OS X,
especially considering Mac OS X 10.4 will be available later this week.

Thanx. Yea, I was going to upgrade soon anyway, I was just trying to get it
to run so I could learn now :stuck_out_tongue:

Thanks for you help!
