Installing OGRE XCode template for iOS

This is the continuation of my previous blog Building OGRE for iOS. To install the template, you need to follow these steps.

OGRE XCode template

This will install the OGRE template for you. Let us create our first sample OGRE demo using the template we installed it now. To do that, open XCode and select the OGRE template and hit next.

If you see the next attached screenshot carefully, for some reason, the XCode was not letting me add ‘/’ at the beginning of the root SDK path of OGRE. Just ignore it for now. Lets correct this later by making few changes in the XCode project settings.XCode project creation

Now, select the target ‘DemoApp’. Now, select ‘Header Search Paths’ under ‘Build Settings’ and add the missing ‘/’ . Also, make the same changes for ‘Library Search Paths’ too 🙂

Now. it’s time to compile the app. If you have done everything right then you should see this error 🙂

To fix this error, add -lboost_system in the Other Linker Flags. That’s it…Compile and Run the program now. You should see the OGRE beast staring at you 🙂

One thought on “Installing OGRE XCode template for iOS

  1. Hi Praveen,
    Thanks for a tutorial which is finally up to date 🙂 Actually I managed to complete this demo earlier, but thought may be you might know the answer to my question: Is it possible to run Ogre in a separate UIView? I mean combining Ogre with Storyboards, for example, or building UI using Apple’s own framework, then including that view inside MVC. Thank you!
