Question

我正在尝试为arm64构建我的项目。该项目需要arm64 libcrypto.a。我想知道是否缺少任何设置。预先感谢...

我看到的错误是：

我的项目设置如下所示：

ld: warning: ignoring file /Users/Amy/Desktop/swift_proj/swift_proj/include/libcrypto.a, file was built for archive which is not the architecture being linked (x86_64): /Users/Amy/Desktop/swift_proj/swift_proj/include/libcrypto.a

我已将info.plist中的“ RequiredDeviceCapabilities”更新为arm64。
我已经检查了要链接的库的类型：

Architectures: arm64
Base SDK: Latest iOS(iOS 11.4)
Build Active Architecture Only: No
Supported Platforms: iOS
Valid Architectures: arm64

我不明白为什么该错误说明该项目是针对x86_64构建的。

看起来OpenSSL的多体系结构存在一些问题，您需要解决该问题才能使其正常工作，这里的Build Multiarch OpenSSL on OS X答案应该有所帮助。

基本上，您必须使用#ifdef替换几个包含特定于体系结构的头的OpenSSL头文件，以在编译时检查系统体系结构。从源构建所需的每个目标的OpenSSL之后执行此操作。然后，您将能够使用lipo工具将针对OpenSSL的每个目标的静态库构建组合到一个静态库中，然后使用它。
