Subject [jira] [Commented] (HADOOP-8187) Improve the discovery of the jvm library during the build process
Date Tue, 25 Sep 2012 00:26:08 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13462298#comment-13462298

Allen Wittenauer commented on HADOOP-8187:

I guess you didn't bother actually reading that JIRA.  Here, I'll summarize for you:

Deveraj opened this jira to track future work.  The primarily thought was actually asking
the JVM where the libraries are via system properties.  HADOOP-8737 is a pretty terrible hack
that only works on some platforms. By asking the JVM, one should only need to port to a JVM
rather than an entire OS*. Sample code I wrote a while back for Sun's JVM exists in HADOOP-6924.

* - As usual, OS X is a bit of a troublemaker since (by default) libjvm.dylib is only 32-bit
on at least Snow Leopard in some JVM versions.  (I'll leave it as an exercise for the reader
to figure out why.)  But by passing by the appropriate flags at compile time, it will get
built the fat binary version of libjvm and the problem goes away.

> Improve the discovery of the jvm library during the build of native libraries/libhdfs/fuse-dfs,
etc. A couple of different ways are currently used (discussed in HADOOP-6924). We should clean
this part up and also consider builds of native stuff on OSX.
