Subject [jira] [Commented] (HADOOP-6924) Build fails with non-Sun JREs due to different pathing to the operating system architecture shared libraries
Date Sat, 17 Mar 2012 22:48:38 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6924?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13232092#comment-13232092
] 

Devaraj Das commented on HADOOP-6924:
-------------------------------------

I don't want to hold the commit of this really really simple two line patch that improves
the build in a big way.

Allen, could you please submit your ideas as a patch on how to make it work on a Mac (you
seemed to indicate you had a solution that is more general). I'd suggest you open a separate
jira to track that approach.

Hope it makes sense to everyone.

> The src/native/configure script used to build the native libraries has an environment
variable called JNI_LDFLAGS which is set as follows:
> JNI_LDFLAGS="-L$JAVA_HOME/jre/lib/$OS_ARCH/server"
> This pathing convention to the shared libraries for the operating system architecture
is unique to Oracle/Sun Java and thus on other flavors of Java the path will not exist and
will result in a build failure with the following exception:
>      [exec] gcc -shared  ../src/org/apache/hadoop/io/compress/zlib/.libs/ZlibCompressor.o
../src/org/apache/hadoop/io/compress/zlib/.libs/ZlibDecompressor.o  -L/home/hadoop/Java-Versions/ibm-java-i386-60/jre/lib/x86/server
-ljvm -ldl  -m32 -m32 -Wl,-soname -Wl,libhadoop.so.1 -o .libs/libhadoop.so.1.0.0
>      [exec] /usr/lib/gcc/i586-suse-linux/4.1.2/../../../../i586-suse-linux/bin/ld: cannot
find -ljvm
>      [exec] collect2: ld returned 1 exit status
