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.
