当我尝试编译和运行(使用Xcode)时,它会引发38个链接错误

您需要将Crypto++标头和库添加到Xcode项目中。下面的图像取自,并假定Crypto++安装在
/usr/local/cryptopp

在此处添加标题:

在此处添加库:

如果您是为iOS交叉编译(也是Mach-O),Crypto++wiki有几个关于这个主题的页面:

如果您想使用ARMv7、ARMv7s、ARM64和i386(模拟器)为iOS预先构建Crypto++,请参见此


在自己创建库之前,应该打开makefile(
GNUmakefile
),并取消注释
cxflags=-fPIC

<> P>也因为<代码> >包含< /C> >,您可能需要添加<代码> CXXFLAG++-STDC++11 。我不确定,因为我不记得尝试MIC C++ 03和C++ 11。
Crypto++5.6.2及更早版本在Intel平台上也需要
-dcryptoppp\u DISABLE\u ASM
,因为Clang的集成汇编程序和Apple的底层链接器

Crypto++5.6.3及以上版本解决了大多数问题。无法有效解决的问题已将
-DCRYPTOPP\u DISABLE\u ASM
应用于有问题的翻译单元,而不是整个库
