Universal static library 만들기

static library나 주어온 framework를 프로젝트에 포함시켜 컴파일 하다 보면 simulator에서는 되지만, device에서는 에러가 나는 경우가 있다. 거꾸로 이거나…

… missing required architecture i386 in file

이는 library나 framework 소스가 있다면, 다시 재컴파일해서 집어넣어줘야 한다. 이를 Universal library라 부른다.

1. Target에 “Run Script”를 추가한다. 그리고, 다음의 긴 코드를 넣어준다.

 

# Version 2.0 (updated for Xcode 4, with some fixes)
# Changes:
# – Works with xcode 4, even when running xcode 3 projects (Workarounds for apple bugs)
# – Faster / better: only runs lipo once, instead of once per recursion
# – Added some debugging statemetns that can be switched on/off by changing the DEBUG_THIS_SCRIPT variable to “true”
# – Fixed some typos
#
# Purpose:
# Create a static library for iPhone from within XCode
# Because Apple staff DELIBERATELY broke Xcode to make this impossible from the GUI (Xcode 3.2.3 specifically states this in the Release notes!)
# …no, I don’t understand why they did this!
#
# Author: Adam Martin – http://twitter.com/redglassesapps
# Based on: original script from Eonil (main changes: Eonil’s script WILL NOT WORK in Xcode GUI – it WILL CRASH YOUR COMPUTER)
#
# More info: see this Stack Overflow question: http://stackoverflow.com/questions/3520977/build-fat-static-library-device-simulator-using-xcode-and-sdk-4

# IF this is the original invocation, invoke WHATEVER other builds are required
#
# Xcode is already building ONE target…
#
# …but this is a LIBRARY, so Apple is wrong to set it to build just one.
# …we need to build ALL targets
# …we MUST NOT re-build the target that is ALREADY being built: Xcode WILL CRASH YOUR COMPUTER if you try this (infinite recursion!)
#
#
# So: build ONLY the missing platforms/configurations.

then
