OSX 10.5 compile problems introduced in 20298a0d8631

Revision 20298a0d8631 introduced compile errors in OSX 10.5. Here are
the errors:

http://pastie.org/8217269

I’m no Obj-C syntax guru, but I know at least the ‘block’ syntax in
this snippet wasn’t introduced until 10.6:

At SDL_cocoamousetap.m:168:
—snip—
CFRunLoopPerformBlock(tapdata->runloop, kCFRunLoopCommonModes, ^{
/* We signal this after the run loop has started, indicating
it’s safe to CFRunLoopStop it. */
SDL_SemPost(tapdata->runloopStartedSemaphore);
});
—snap—

We don’t support building with 10.5 SDKs. SDL_platform.h should give you
an #error if you use anything lower than 10.6 to build.

That aside, I believe that there’s no runtime support for blocks on 10.5
either, so this code is likely not working even if it builds like that.
I’ll look into it.

Hi,

Hmmm… so running on 10.5 is supported, just not building with the
10.5 SDK? I didn’t know you could build for 10.5 with the 10.6 SDK.

I suppose I can work around it by using: #define SDL_MAC_NO_SANDBOX 0

Thanks for your response

Yes, setting the Deployment Target lets you build a program that targets an
earlier minimum version of OS X than what your SDK is labelled as.

SDL’s Xcode project uses the latest available SDK on your system but has
the deployment target set to OS 10.5 by default.

That #define wasn’t intended to ship like that - it is something I meant for people to enable explicitly if they wanted that functionality. Thanks for letting me know - I’ve now updated it so that it’s not enabled by default.

I’ll look at making that code work on 10.5 though, since it shouldn’t be 10.6 specific.

After the most recent commit, this should now work on 10.5 too, even if you define SDL_MAC_NO_SANDBOX=1.
