SDL on Mac OS X 10.4 - 10.5

SDL Development
1

We’ve run into a bit of trouble running our SDL-based framework on OSX 10.4,
when compiled on a 10.5 machine :

dyld: Symbol not found: _NSDefaultRunLoopMode

Using nm -mg, we’ve determined it’s SDL the one that links to this symbol.

Is there an easy way to fix this (ie without having to install a 10.4
environment?) Which version is the one downloadable from the website
compiled for?

Thanks,
–Gabriel

Hi Gabriel-

In 10.5 and later, that symbol is defined in CoreFoundation.framework;
in 10.4 and before it’s in Foundation.framework. Linking against
Foundation.framework should solve the problem.On 12 Mar 2009, at 15:09, Gabriel Gambetta wrote:

Thanks for the tip, Alastair - we still can’t fix the problem.

otool shows that our libSDL.dylib is linked to both Foundation and
CoreFoundation; our binary is linked to both, too. We’re not linking to
either of these explicitly, though.

Our binary is linked with -framework Cocoa -framework OpenGL -lSDL; I’m
not sure about the relationship between the frameworks and the libraries. Do
you think this may be a problem?

Thanks,

The official SDL.framework from the website is intended to scale for 10.2
through 10.5. (It may even work as far back as 10.0 though I don’t think
anybody has tried in a long time.)

Can you look and see why this doesn’t work?

We tried used the framework but the game hangs up on start. We’re now trying
compiling the dylib using -isysroot and the other cross-compiling gcc
switches.

I just did some testing but could not reproduce
any problems.

I downloaded the DMGs, installed the framework and Xcode templates. I used
the SDL Application and SDL OpenGL Application templates to create two
projects.

I built and compiled both projects using the 10.5 SDK on my Leopard Xcode
3.1 machine. No problems building or running.

Testing on my G4 Powerbook building Unversal. Did not try running on Intel.
But I’m not expecting trouble there.

We’re still having trouble with this…

Does anyone have libsdl.dylib compiled in 10.4 and can share it?

We’ve tried compiling using -isysroot and -mmacosx-version-min but that
hasn’t solved our issues.

Unfortunately, this happens on a test machine we don’t have here, and the
build does work in some other 10.4 machines…

If someone could send me a libsdl.dylib compiled in 10.4, I’d be most
grateful.

Thanks,

Apparently, our build works with 10.4.8, but it doesn’t work in 10.4.11.On Wed, Mar 18, 2009 at 5:14 PM, Gabriel Gambetta wrote:
