Updated main.c for API changes Kees Bakker to sdl The main.c for the template is still targeting SDL1.2. Here is the patch to make it work for SDL1.3 (I'm hoping the mailing lists accepts attachments.) In this patch I have also changed the shell script that assembles the Template. Since there is now only one lib target (same name for "device" and "simulator" version) I copy the simulator library to the destination with the name libSDLSimulator.a. This is not a satisfactory solution, because both libraries are included in the project while only one is needed (depending on the selected environment). However, I'm not fluent with Xcode to say what a better solution would be. Kind regards, Kees Bakker
