Subject [jira] [Created] (HADOOP-8569) CMakeLists.txt: define _GNU_SOURCE and _LARGEFILE_SOURCE
Date Fri, 06 Jul 2012 06:29:35 GMT
Colin Patrick McCabe created HADOOP-8569:

             Summary: CMakeLists.txt: define _GNU_SOURCE and _LARGEFILE_SOURCE
                 Key: HADOOP-8569
                 URL: https://issues.apache.org/jira/browse/HADOOP-8569
             Project: Hadoop Common
          Issue Type: Bug
            Reporter: Colin Patrick McCabe
            Assignee: Colin Patrick McCabe
            Priority: Minor

In the native code, we should define _GNU_SOURCE and _LARGEFILE_SOURCE so that all of the
functions on Linux are available.

_LARGEFILE enables fseeko and ftello; _GNU_SOURCE enables a variety of Linux-specific functions
from glibc, including sync_file_range.
