Subject [jira] [Commented] (HADOOP-7276) Hadoop native builds fail on ARM due to -m32
Date Fri, 27 May 2011 21:43:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7276?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13040460#comment-13040460

Eli Collins commented on HADOOP-7276:

I don't see the findbugs warning locally. Don't think a test is needed since this to get the
code compiling.

     [exec] -1 overall.  
     [exec]     +1 @author.  The patch does not contain any @author tags.
     [exec]     -1 tests included.  The patch doesn't appear to include any new or modified
     [exec]                         Please justify why no new tests are needed for this patch.
     [exec]                         Also please list what manual steps were performed to verify
this patch.
     [exec]     +1 javadoc.  The javadoc tool did not generate any warning messages.
     [exec]     +1 javac.  The applied patch does not increase the total number of javac compiler
     [exec]     +1 findbugs.  The patch does not introduce any new Findbugs (version 1.3.9)
     [exec]     +1 release audit.  The applied patch does not increase the total number of
release audit warnings.
     [exec]     +1 system test framework.  The patch passed system test framework compile.

> 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.
