ARM64 build error during building libetpan project

Question

While building libetpan for iOS-ARM64,

I've been added logging functionality on prepare script on libetpan for mac project. Xcode fails with strange error, only during build ARM64 target. Here's the xcode log below:

CONFIGURE FAILED.

The build script generated its own build log file. It ends with "Malformed object" message like below:

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

Any ideas? Thanks in advance.

I ran into the same problem after updating iPhone SDK from 7.0 to 7.1. I fixed it by changing ranlib and ar paths, they were pointing to some old version of those applications (/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ranlib and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/ar).

I changed the path to: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ar
