XCode 5中的胖库 [英] Fat libraries in XCode 5

问题描述

我一直在尝试构建一个静态库，然后在Xamarin中创建一个绑定项目。一切正常，直到iOS 7出现。我不得不抓住最新版本的本机库并尝试在XCode 5中构建它，但它一直给我各种各样的问题。我认为它可能与构建过程有关，或者可能与XCode 5中的某些更改设置有关（对比4），但我不确定。

<我正在使用这个

使用Xcode和SDK 4+构建胖静态库（设备+模拟器）

我注意到的一件事就是之前，在我的二进制版本的旧版iOS 6.1版本（内置在XCode 4中）中，我的二进制文件大约是24 Mb，现在使用XCode 5，它已经膨胀到接近50 Mb！这让我觉得编译和链接步骤有问题。

有什么想法吗？有没有其他人在XCode 5（vs 4）中遇到通用二进制文件的问题？

解决方案

我正在使用下面的makefile库甚至使用XCode 5和iOS7 SDK也能完美无缺。

  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发布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发布清理版本
 -mv $（PROJECT_ROOT）/ build / Release-iphoneos / lib $（TARGET）.a $ @

 lipo -create -output lib $（TARGET）Universal.a $ ^ 
 
 clean：

 -rm -rf build 
  

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 version of the native library and try and build it in XCode 5, but it's been giving me all kinds of problems. I think it might be related to the build process or possibly some changed setting in XCode 5 (vs. 4) but I'm not sure.

I was using this script to build a universal binary which is based of work in this question:

Build fat static library (device + simulator) using Xcode and SDK 4+

One thing I did notice is that previous, in the old iOS 6.1 version of my binary (built in XCode 4), my binary was about 24 Mb, now with XCode 5 it's ballooned to almost 50 Mb! Which is leading me to think that there is something wrong with the compiling and linking step.

Any ideas? Has anybody else encountered problems with universal binaries in XCode 5 (vs 4)?

解决方案

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
