【问题描述】：
我想使用适用于 iOS 的 Pax86 库。最初我尝试手动创建库，因为我拥有所有必需的文件。但它由带有代码的文件组成，用于创建一个可以在终端上运行但仅适用于 iPhonesdk4.3 的静态库。由于我有 iPhonesdk7.1，我无法创建 Pax86 库。我没有带 iPhonesdk4.3 的系统。后来提供了基于 iPhoneSDK4.3 构建的静态库。
我将静态库 (.a) 文件添加到了新项目中，还将 pax86 的“包含”文件添加到了新应用程序中。 当我尝试调用任何与 pax86 相关的方法时，出现如下错误：

我已将“构建活动架构”设置为“是”和“否”，删除了所有其他架构，如 armv7s、arm64 等，但仍然出现上述问题。
我什至已将 .a 文件添加到 usr/lib，然后将其添加到构建设置中。清除了库搜索路径和框架搜索路径。
我导入了所附屏幕截图中的静态库，即使没有“包含”也尝试过。
您能帮我解决这个问题吗？是不是因为静态库仅适用于 iPhoneSDK4.3 而不是 iPhoneSDK7.1 或任何其他 SDK。我也在 iPhoneSDK3.2 中尝试过，但没有运气。
请帮忙。
提前致谢。
【问题讨论】：
-
您需要在命令行中使用
lipo -info检查库中包含的架构。 -
包含的架构是armv7。在带有静态库的新应用程序中，我已将“架构”更改为 armv7，将“有效架构”更改为 armv7。但同样的错误发生了。我有 Xcode 5.1.1 和 OS X 10.8.5 。我已经在 iPad2 上用 iOS 7.1 测试过它。 @Droppy
-
好的，我错过了错误消息“存档没有目录文件”，因此看起来静态库已损坏。您可以尝试使用
ar提取目标文件并尝试重新添加它们，但我从未使用 fat binaries 这样做。
