Stephen Watt commented on HADOOP-6924:
--------------------------------------
That sounds like a good approach Allen. Something that greps forward from the
$JAVA_HOME/jre/lib directory for the libjvm.so to determine the path would be
quite elegant and much simpler than trying to divine the OS Architecture
signature and build the right path.
> Build fails with non-Sun JREs due to different pathing to the operating
> system architecture shared libraries

> Key: HADOOP-6924
> URL: https://issues.apache.org/jira/browse/HADOOP-6924
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 0.20.0, 0.20.1, 0.20.2
> Environment: SLES 10, IBM Java 6
> Reporter: Stephen Watt
> Fix For: 0.20.3
>
>
> 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
