X $ C $Ç - 符号（S）未找到x86_64的架构（IOS库） [英] Xcode - symbol(s) not found for architecture x86_64 (iOS Lib)

问题描述

我建立一个静态库。构建设置已经设置到体系结构： $（ARCHS_STANDARD）被示为标准架构（ARMv7的，armv7s，arm64）我建的lib选择iOS设备，然后使用仿真器（例如iPhone的Retina）。

现在，我有两个版本（一个在调试-的iPhoneOS 和其他内部调试 - iphonesimulator ，我使用脂-create 以创建聚集的lib目录下：

 脂 - 创建路径/要/首/ lib目录/路径/要/秒/ lib目录-o mylib.a上
 

如果我用这个库中的另一个项目，以模拟在任何iOS设备与64位架构，它提供了符号（S）未找到架构的x86_64 。真正让我气得的lib项目本身是与使用的lib另一个项目工作区中。我可以模拟64位的iOS模拟器！ （所有的模拟器和设备为此事）。我究竟做错了什么？

注：

1. 在此不重复的问：在指责我的那个（因为这是我的第二天试图解决这个愚蠢的问题），我也搜索堆栈和谷歌。所有的答案都没有帮助。
2. 我用X code 5.1.1。

解决方案

我有同样的麻烦建立静态库。
最后，我已经找到了基本解决。 （您需要构建 x86_64的 / 通用库的ARMv7 / armv7s / arm64 ）

1）点击项目文件
2）点击目标
3）打开构建阶段
4）打开运行脚本
5）加入/ bin / sh的及以下

I am building a static library. The build setting has the Architectures set to: $(ARCHS_STANDARD) which is shown as Standard Architectures (armv7, armv7s, arm64) I build the lib choosing iOS Device AND then using the simulator (for example iPhone Retina).

Now that I have two builds (one inside Debug-iphoneos and the other inside Debug-iphonesimulator, I use lipo -create to create the aggregated lib:

lipo -create path/to/first/lib /path/to/second/lib -o MyLib.a

If I used this library in another project to simulate on any iOS device with 64-bit architecture, it gives symbol(s) not found for architecture x86_64. What really makes me so angry that the lib project itself is inside a workspace with another project that use the lib. I can simulate on 64-bit iOS simulator! (on all simulators and devices for that matter). What am I doing wrong?

Notes:

1. This is not duplicate Q. Before accusing me of that (since this is my second day trying to fix this stupid issue), I did search on Stack and Google. All answers don't help.
2. I am using Xcode 5.1.1.

解决方案

I had the same trouble with building static library.
Finally I have found the basic solution. (You need to build universal library for x86_64/armv7/armv7s/arm64)

1) Click on the project file
2) Click on the target
3) Open "Build Phases"
4) Open "Run Script"
5) Add "/bin/sh" and the script below

# Version 2.7
#
# Latest Change:
# - Supports iPhone 5 / iPod Touch 5 (uses Apple's workaround to lipo bug)
#
# Purpose:
#   Automatically create a Universal static library for iPhone + iPad + iPhone Simulator from within XCode
#
# 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)

6) Hit "cmd + B" (Build Project)

7) Open Product in Finder

8) Navigate 1 directory up ("cmd + ↑"), and you will see "Release-universal" directory.

There will be your "fat/universal" library, You are ready to go!
