- Setup the JAVA_HOME environment variable. The
java
executable is supposed to be found in$JAVA_HOME/bin/java
- Setup the ROOT environment:
source <wherever you installed ROOT>/bin/thisroot.sh
- Cd to the javaROOT directory.
- Run
make OSTYPE=linux-gnu all
. - Tell the linker where to find the new shared objects. E.g. if running the example "C++", calling export LD_LIBRARY_PATH:$LD_LIBRARY_PATH:. is necessary for the program to run.
- Running the Java programs requires the classpath to be set approriately, e.g. java -cp ../../jar/javaROOT.jar:../../jar/freehep-physics-2.1.jar:. Test.
- If there are any problems with network exceptions on the LCSIM example, it is due to proxy servers: set these when Java is run by adding -Dhttp.proxyHost=<hostname> -Dhttp.proxyPort=<hostport> in the call to Java.
