在使用 GPUImage 构建应用程序时，我遇到了这样的错误
ld: warning: directory not found for option '-L/Users/.../GPUImage'
ld: warning: ignoring file /Users/.../Libraries/GPUImage/libGPUImage.a, missing required architecture x86_64 in file /Users/.../Libraries/GPUImage/libGPUImage.a (3 slices)
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_GPUImageCrosshatchFilter", referenced from:
objc-class-ref in AddPopViewController.o
我不知道这个错误是否相关，但我想做的是让我的应用程序支持 64 位处理器。我怎样才能做到这一点？ 在这个link , 它说
The framework supports 64-bit, but you'll have to enable this for your project in the framework and your application yourself
我该怎么做？谢谢
最佳答案
以下是 iOS documentation 中给出的步骤确保应用程序支持 64 位。检查您的环境中是否注意以下几点。
概括地说，以下是创建面向 32 位和 64 位运行时环境的应用的步骤:
- Install the latest Xcode.
- Open your project. Xcode prompts you to modernize your project. Modernizing the project adds new warnings and errors that are important when compiling your app for 64-bit.
- Update your project settings to support iOS 5.1.1 or later. You can’t build a 64-bit project if it targets an iOS version earlier than iOS 5.1.
- Change the Architectures build setting in your project to "Standard Architectures (including 64-bit)."
- Update your app to support the 64-bit runtime environment. The new compiler warnings and errors will help guide you through this process. However, the compiler doesn’t do all of the work for you; use the information in this document to help guide you through investigating your own code.
- Test your app on actual 64-bit hardware. iOS Simulator can also be helpful during development, but some changes, such as the function calling conventions, are visible only when your app is running on a device.
