在为 iOS-ARM64 构建 libetpan 时，

我已经在 libetpan for mac 项目的准备脚本中添加了日志记录功能。 Xcode 失败并出现奇怪的错误，仅在构建 ARM64 目标期间。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“格式错误的对象”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？提前致谢。

【解决方案1】：

在将 iPhone SDK 从 7.0 更新到 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，它们指向这些应用程序的一些旧版本（/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ranlib 和 /Applications/Xcode .app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar)。

我将路径更改为： /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar
