This provides a Java interface to a (very) limited subset of ROOT. The code for this is currently stored on the SVN server (https://heplnm060.pp.rl.ac.uk/repos/javaROOT/tags/0.1.0).
...
- Scientific Linux Fermi version 4.7, GCC version 3.4.6, Java version 1.6.0.13, ROOT version 5.24 and SWIG version 1.3.39.
- Windows XP SP3, Microsoft C++ Compiler version 15.00.30729.01, MinGW 5.1.4, Java version 1.6.0.14, ROOT version 5.24 and SWIG version 1.3.3940.
- OpenSuse 10.2 GCC 4.3.2 Java version 1.6.0.13, ROOT version 5.22 and SWIG version 1.3.36.
The libraries are built using a set of makefiles. (On Windows, these are executed using the MinGW port of GNU make, mingw32-make.)
There are a set of example programs demonstrating the available functionality in ./Examples/. These are also built when the main libraries are built with "make all".
There are also a series of tests in ./Tests/ to check that certain basic ROOT functions work correctly on your platform. These are built and run using ./make Tests.
Using the libraries (Linux)
- Setup the ROOT environment by running $ROOT_SYS/bin/thisroot.sh.
- Cd to the javaROOT directory.
- Run make all.
- Tell the linker where to find the new shared objects. E.g. if running the example BasicC"C++", calling export LD_LIBRARY_PATH:$LD_LIBRARY_PATH:. will ensure is necessary for the program runsto 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.
