Scientific Linux Fermi version 4.4, GCC version 3.4.6, Java version 1.6.0.13, ROOT version 5.24 25 and SWIG version 1.3.3940.
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 25 and SWIG version 1.3.40.
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.)

javaROOT requires SWIG version 1.3.40 or higher, and on Windows, ROOT v.5.25.

javaROOT can:

create histograms (TH1Fs, TH1Ds, TH2Fs, TH2Ds, TProfiles) and fill them with data.
create TTrees and fill them with data (branches of type float, int, double, bool, TVector3, TLorentzVector, std::vector<float>, std::vector<int>, std::vector<double>, std::vector<bool>, std::vector<TVector3>, std::vector<TLorentzVector>).

...

Ensure the %ROOT_SYS% and %JDK_HOME% environment variables are set (go to System Properties (WinKey+Break), Advanced, Environment Variables) to the root folders of ROOT and the JDK respectively.
Run a Visual Studio Command Prompt.
Cd to the javaROOT root folder.
Run mingw32-make all.
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.
