为iOS-ARM64构建libetpan时，
我已经在libetpan for mac project上的prepare脚本上添加了日志记录功能。只有在构建ARM64目标期间，Xcode才会出现奇怪的错误。 这是下面的xcode日志：

CONFIGURE FAILED.
构建脚本生成了自己的构建日志文件。它以“Malformed object”消息结束，如下所示：
ar cru .libs/libsasldb.a db_ndbm.o allockey.o
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ranlib: object: .libs/libsasldb.a(allockey.o) malformed object (unknown load command 1)
ar: internal ranlib command failed
make[2]: *** [libsasldb.a] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
有什么想法吗？提前谢谢。

将iPhone SDK从7.0升级到7.1后，我遇到了同样的问题。 我通过更改ranlib和ar路径来修复它，它们指向那些应用程序的旧版本（/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ranlib和/ Applications / Xcode 。应用程序/内容/开发商/平台/ iPhoneOS.platform /开发人员的/ usr /斌/ AR）。
我改变了路径： /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar
