Can't get SDL to work... Help please!
Post: #1
Hi, I can't get any SDL applications to link properly, not even the XCode templates. It always fail with 2 linking errors:
where I belive the most helpful (to someone, not me) is in these lines:
I read another thread where LWStrike (?) seemed to have the same problems but he didn't say how he solved it. I am quite new to Xcode so i'd really appreciate any help I can get.
I am using an iMac core duo, Mac OS X 10.4.6 and XCode 2.2.1. I have installed the SDL runtime and developer libraries.

You have two options:
1. Don't build as a universal binary (ie in the targets inspector, set the architecture to PowerPC only)
2. Use a universal binary version of SDL, which doesn't exist, but you can build it yourself from source. Download everything from this site and then run the script. It will download a bunch of libraries and frameworks and compile them for PPC and Intel or for both (in the case of the OpenAL and SDL frameworks)

1. I'm probably stupid, but I can't get it to work. I choose get info on the project, go to the "Build"-tab and change "Architecture" to "ppc" but it still fails to build. Why?
2. Looks like it is working (downloading and compiling right now). Do I simply replace the SDL.framework with the UB version?
Edit: Every library except SDL downloaded and compiled successfully, seems like "http://www.libsdl.org/cvs/SDL.dmg" isn't working... Anyone got a universal SDL.framework to send me?

Ignore my post above, I managed to compile the framework myself (thanks to the xcode project that came with the SDL source).
Thank you for helping me to find out what was wrong!
