Subject [jira] [Commented] (HADOOP-8489) fix 32-bit native build on 64-bit x86
Date Thu, 07 Jun 2012 18:20:23 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8489?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13291178#comment-13291178

Colin Patrick McCabe commented on HADOOP-8489:

Yeah, you're right.

It seems that CMake gets CMAKE_SYSTEM_PROCESSOR from the output of "uname -p", and on some
older versions of Linux this could return "amd64."

As for passing -m32 to the linker... there are some online sources that recommend doing this
for a 32-bit-build-on-64.  The GNU ld documents themselves seem silent on -m32 itself, although
they do talk about some other options to -m.  So it's probably best to leave this for now,
until we can determine that it's not needed...
