无法从静态库Pax86调用方法

Question

我想使用适用于iOS的Pax86库。最初我尝试手动创建库，因为我有所有必需的文件。但它由带有代码的文件组成，用于创建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。我没有配备iPhonesdk4.3的系统。后来提供了一个基于iPhoneSDK4.3的静态库。

我将静态库（.a）文件添加到新项目中，还包括pax86的“include”文件到新应用程序。 当我尝试调用与pax86相关的任何方法时，会发生错误，如下所述：

对于模拟器：

我将“Build Active Architecture”设置为“YES”和“NO”，删除了所有其他架构，如armv7s，arm64等，但仍然会出现上述问题。

我甚至将.a文件添加到usr / lib，然后在Build Settings中添加它。清除了图书馆搜索路径和框架搜索路径。

我在附带的屏幕截图中导入了静态库，甚至在没有“include”的情况下尝试了。

你能帮我解决一下这个问题。是因为静态库仅适用于iPhoneSDK4.3，而不适用于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。

Answer 1

静态库是为iPhone SDK 4.3构建的，只能使用它。它可能只包含架构armv6的符号，而您尝试在i386（模拟器）和armv7 / armv7s / arm64（设备）中使用。

您的解决方案是使用较新的SDK构建该库。
