Hi Owen,

Thanks for the reply. From the link you provided, I found the build instruction. I do not understand the option, "-Djava5.home=/usr/local/jdk1.5". Does it mean I have to use JDK 1.5? I read somewhere it suggested to use JDK 1.6. 

Also, the very first line is "export JAVA_HOME=/path/to/32bit/jdk
". Does it mean the JAVA_HOME jdk has to be 1.5?  Please let me know.


export JAVA_HOME=/path/to/32bit/jdk
export CFLAGS=-m32
export CXXFLAGS=-m32
ant -Dversion=X.Y.Z -Dcompile.native=true -Dcompile.c++=true -Dlibhdfs=1 -Dlibrecordio=true -Dxercescroot=/usr/local/xerces-c -Declipse.home=/usr/lib/eclipse -Dforrest.home=/usr/local/forrest -Djava5.home=/usr/local/jdk1.5 clean api-report tar test test-c++-libhdfs
export JAVA_HOME=/path/to/64bit/jdk
export CFLAGS=-m64
export CXXFLAGS=-m64
ant -Dversion=X.Y.Z -Dcompile.native=true -Dcompile.c++=true compile-core-native compile-c++ tar


Thanks,


Gary
