Native builds (compile-core-native) fail on Mac OSX due to dependency on 'ldd' or 'objdump'
-------------------------------------------------------------------------------------------

Key: HADOOP-7477
URL: https://issues.apache.org/jira/browse/HADOOP-7477
Project: Hadoop Common
Issue Type: Bug
Components: build
Affects Versions: 0.20.205.0, 0.23.0
Environment: Mac OSX build environment
Reporter: Matt Foley
Assignee: Giridharan Kesavan


When trying to build the patch for HDFS-7432, which is a NativeIO implementation for chmod, it became clear that building the "compile-core-native" target doesn't work on Mac, apparently due to:
{{[exec] checking zlib.h presence... configure: error: Can't find either 'objdump' or 'ldd' to compute the dynamic library for '-lz'}}

These utility programs are not present on Mac. One source suggests using {{otool -L}} instead.
