SDL 1.3 - MacOS X build errors

SDL Development
1

I get some compile errors on a fairly recently SDL 1.3 build I got within the last week. Here’s the first error:

/Users/vernold/SDL Sep 2010 - Won’t Compile/Xcode/SDL/…/…/src/video/cocoa/SDL_cocoawindow.m:298:0 /Users/vernold/SDL Sep 2010 - Won’t Compile/Xcode/SDL/…/…/src/video/cocoa/SDL_cocoawindow.m:298: error: ‘NSTouch’ undeclared (first use in this function)

The others are similar. Sounds like a simple #include that is missing. Which one?

Which SDK are you compiling with? I think NSTouch is fairly new. If
your SDK is too old, then it won’t have the header.

Thanks,

I’m not sure if the OP got his to work, but just wanted to chime in that for me the issue was that the AppKit framework was not linked to in the project. (The AppKit framework contains NSTouch).

But piggy backing on this post, I can’t get my SDL 1.3 source from Mercurial to compile using XCode on 10.6.4. It produces the following link errors:

New user to SDL here, would love to get this working …

Thanks!

I believe it has something to do with the config file, like i posted some
time ago for the iphone project.
You probably need to add HAVE_ATAN2 to your platform config.h file
