Subject [jira] [Commented] (HADOOP-7276) Hadoop native builds fail on ARM due to -m32
Date Thu, 12 May 2011 20:26:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13032649#comment-13032649
] 

Trevor Robinson commented on HADOOP-7276:
-----------------------------------------

No tests included because this change just fixes a build failure. Manually verified that x86-64
builds unchanged (-m64 is properly specified) and that ARM now builds (-m32 is not specified).

Findbugs issue seems to be a configuration issue unrelated to change. From console output:

     [exec] findbugs:

Also, the precommit build queue (https://builds.apache.org/hudson/job/PreCommit-HADOOP-Build/)
seems to be hanging multiple recent jobs at "Recording test results". They're still running
at >1hr.

Would a committer please review the change and let me know if I need to resubmit it?

> The native build fails on machine targets where gcc does not support -m32. This is any
target other than x86, SPARC, RS/6000, or PowerPC, such as ARM.
