Fat libraries in XCode 5

Question

I\'ve been trying to build a static library and then create a binding project from it in Xamarin. Everything was working fine until iOS 7 hit. I had to grab the latest versi

Answer 1

I'm using the makefile below for my library and it works flawless even with XCode 5 and the iOS7 SDK.

XBUILD=/Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild
PROJECT_ROOT=.
PROJECT=$(PROJECT_ROOT)/GIFLibFrontEnd.xcodeproj
TARGET=GIFLibFrontEnd

all: libUniversal.a

libi386.a:
    $(XBUILD) -project $(PROJECT) -target $(TARGET) -sdk iphonesimulator -configuration Release clean build
    -mv $(PROJECT_ROOT)/build/Release-iphonesimulator/lib$(TARGET).a $@

libArmv7.a:
    $(XBUILD) -project $(PROJECT) -target $(TARGET) -sdk iphoneos -arch armv7 -configuration Release clean build
    -mv $(PROJECT_ROOT)/build/Release-iphoneos/lib$(TARGET).a $@

libArmv7s.a:
    $(XBUILD) -project $(PROJECT) -target $(TARGET) -sdk iphoneos -arch armv7s -configuration Release clean build
    -mv $(PROJECT_ROOT)/build/Release-iphoneos/lib$(TARGET).a $@

libArm64.a:
    $(XBUILD) -project $(PROJECT) -target $(TARGET) -sdk iphoneos -arch arm64 -configuration Release clean build
    -mv $(PROJECT_ROOT)/build/Release-iphoneos/lib$(TARGET).a $@

libUniversal.a: libi386.a libArmv7.a libArmv7s.a libArm64.a
    lipo -create -output lib$(TARGET)Universal.a $^

clean:
    -rm -f *.a *.dll
    -rm -rf build

Here's a link to a Makefile with the tabs, and I made a little change to separate out the target name from the library name. Thanks very much for this! This solved my problem!
