Unsupported compiler 'GCC 4.2' selected for architecture 'armv7' 에러 발생시

2012.01.11 11:26
 iOS5로 업그레이드 하고, 예전 소스를 실행해보니 

Unsupported compiler 'GCC 4.2' selected for architecture 'armv7'

라는 에러가 발생했다. 해결방법은 다음과 같다.

해당 Project - Build Setting 에서 Build Options의 Compiler for C/C++/Objective-C 부분의 Compiler를

GCC 4.2 이외의 컴파일러로 선택해주면 된다.
