Xcode - 找不到架构 x86_64 (iOS Lib) 的符号 [英] Xcode - symbol(s) not found for architecture x86_64 (iOS Lib)
本文介绍了Xcode - 找不到架构 x86_64 (iOS Lib) 的符号的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在构建一个静态库.构建设置将架构设置为:$(ARCHS_STANDARD) 显示为 Standard Architectures (armv7, armv7s, arm64) 我选择 iOS 设备构建库，然后使用模拟器(例如 iPhone Retina).
现在我有两个版本(一个在 Debug-iphoneos 内，另一个在 Debug-iphonesimulator 内，我使用 lipo -create创建聚合库:
lipo -create path/to/first/lib/path/to/second/lib -o MyLib.a如果我在另一个项目中使用这个库在任何具有 64 位架构的 iOS 设备上进行模拟，它会给出找不到架构 x86_64 的符号.真正让我生气的是 lib 项目本身与另一个使用 lib 的项目位于一个工作区中.我可以在 64 位 iOS 模拟器上模拟！(在所有模拟器和设备上).我做错了什么?
注意事项:
- 这不是重复的问题.在指责我之前(因为这是我尝试解决这个愚蠢问题的第二天)，我确实在 Stack 和 Google 上进行了搜索.所有的答案都没有帮助.
- 我使用的是 Xcode 5.1.1.
解决方案
我在构建静态库时遇到了同样的问题.
最后我找到了基本的解决方案.(需要为x86_64/armv7/armv7s/arm64构建通用库)
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) 添加"/bin/sh"和下面的脚本
6) 点击"cmd + B" (Build Project)
7) 在 Finder
8) 向上导航 1 个目录(cmd + ↑")，您将看到 Release-universal" 目录.
将会有你的fat/universal"库，你准备好了！
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:
- 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.
- 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
