Stephen Watt updated HADOOP-6924:
---------------------------------
Attachment: HADOOP-6924.patch
This is a one line fix that identifies the location of the appropriate
libjvm.so file. For Sun systems this is under the jre/lib/$OS_ARCH/server
folder for IBM JREs this is under the jre/lib/$OS_ARCH/classic folder. Non-Sun
JREs do not have a sun.boot.library.path environment variable that can be
relied upon.
This is also easily extensible as other JREs (such as Apache Harmony) can
simply extend the regular expression by adding in an "OR" expression for a
folder that is unique to their JRE.
> Build fails with non-Sun JREs due to different pathing to the operating
> system architecture shared libraries

> 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
