I am newbie in the area of opengl and iphone development, but I found this project very interesting and spent a few days to get know it better . Following this steps I successfully run that demo on iPhone Simulator:

1. xcode - I've downloaded and installed latest Xcode (xcode_3.2.3_and_ios_sdk_4.0.2.dmg) from apple developer page.
2. cmake - usign existing macports I've installed cmake 2.8.2 (with command line
   Code:

   port install cmake

   ), I suppose that downloading compiled version from http://www.cmake.org/cmake/resources/software.htmlshould be even easier.
3. source - using svn from command line, in my Documents folder I've executed
   Code:

   svn co http://gamekit.googlecode.com/svn/trunk/ gamekit-read-only

   . And checked out revision nr 615 of the source tree.
4. crate project - cd into new gamekit-read-only directory, create buil directory and execute cmake
   Code:

   cd gamekit-read-only
   mkdir build && cd build
   cmake .. -G Xcode -D OGREKIT_BUILD_IPHONE=1 -D OGREKIT_BUILD_GLESRS=1
    OGREKIT_BUILD_GLRS=0

5. build - run Xcode and open and build project OGREKIT.xcodeproj from gamekit-read-only/build/ . Building process took c.a. 20-30 minutes.

1. change target config - Targeted Device Family - to iPad
2. change Architecture i Valid Architecture to armv7
3. put valid Code Signing Identity
4. check off Compile for Thumb - I'm not sure if this is right solution, but with this option checked on I got 6 compile errors f.e."error: branch out of range in Engine/AI/gkNavPath.cpp"

• It is staring/loading - 40 seconds.
• It starts only once, or only run via Xcode and usb cable. After disconecting from mac, and trying to run by pressing app icon it just shows black screen for 40 seconds and switches off.
• It looks and sounds great, render fast, but it restponds to touch events after 15-20 seconds.

OGRE build가이드

오거는 Cmake를 사용한다. 이 가이드는 이에 대한 설명이다.

1. CMake?

CMake는 cross-platform build system이다. CMake script들의 셋으로 native build시스템을 오거 빌드를 위해 만들어준다.

2. CMake는 어디서 나나?

http://www.cmake.org(Resources -> Downloads)에서 구할수 있다. 소스로도 받을 수 있지만 이미 컴파일된 모든 플랫폼의 바이너리들을 다운받을 수 있다. 

3. Dependency들은 어디서 구하나?

freetype lib가 필요한데 그 외에 다른 것들이 더 필요하다. 소스또는 바이너리를 각 배포사이트를 통해서 얻을 수 있다. ogre에서도 몇몇 플랫폼들에 대해서 미리컴파일된 디펜던시들을 별도로 제공하고 있다.

http://www.ogre3d.org/download/source 를 참조하라.

Linux에서는 디펜던시를 바로 설치가 가능하다. Ubuntu Karmic의 경우 다음 명령으로 설치가 가능하다.
