Xcode SDL2 issue: "Undefined symbols for architecture i386"

1. Which SDL2 headers are you using?
2. Sure you got all the development libs? (And for the right arch?)

I'm using these headers:

https://github.com/ev1313/Pascal-SDL-2-Headers

And have installed the Mac OS X SDL 2 frameworks from the official sources (I mean, I didn't install them from source files, I downloaded the .dmg's from the official websites and installed them by copying the frameworks into the Library/Frameworks/ folder). There's only one .dmg to choose for SDL2, SDL2_image and SDL2_mixer, respectively.

I'm also using the Xcode 4 Objective Pascal templates from here:

I'm fairly sure that it's an issue with Xcode not finding the SDL 2 libraries/frameworks during linking, but I don't know how to fix that. I've tried setting the framework path in Build Settings, but that didn't help.

[Christian Knudsen]

Finally some progress!

I had to add:

{$IFDEF DARWIN}
{$linkframework Cocoa}
{$linkframework SDL2}
{$linkframework OpenGL}
{$linkframework SDL2_image}
{$linkframework SDL2_mixer}
{$ENDIF}

To the main source file to get it to compile. I have no idea why, though. It now crashes when setting up the OpenGL context during runtime, but at least it's compiling now!

[Super Vegeta]

ev1313's headers use {$LINKLIB} to specify linking to SDL2. I'm guessing that because you put the SDL2 lib in Frameworks/, {$LINKLIB} failed to find them so you had to use {$LINKFRAMEWORK}.

[Christian Knudsen]

Ahhh, that makes sense! There should probably be a notice about that in a readme or somewhere else, since per the installation instructions on the SDL2 website, most people will probably install the frameworks in Library/Frameworks.

I also fixed the OpenGL crashing issue (I had OpenGL was set to PROFILE_CORE when it should be PROFILE_COMPATIBITY as I'm using immediate mode). I've never been this relieved to just manage to compile and run some code before!
