\subsection bindings_binding_java_install How to install Simgrid-java
To use java with Simgrid you have to install some dependencies:
-- Simgrid (see [install Simgrid](http://simgrid.gforge.inria.fr/simgrid/latest/doc/install.html).
- You should set the `SIMGRID_ROOT` environment variable to the path where you installed SimGrid.
- Java JDK packages, such as `openjdk7` or `sun-java6-jdk` (with `libgcj10-dev` or another
version of gcj). For maximal performance and scalability, use a coroutine-enabled JVM (see
\ref bindings_binding_java_coroutines).
-Then Download and install package Simgrid-java:
+Then build Simgrid with the Java bindings enabled:
~~~~{.sh}
-git clone git://scm.gforge.inria.fr/simgrid/simgrid-java.git
-cd simgrid-java
-cmake -DCMAKE_INSTALL_PREFIX=$HOME/Install/simgrid-java/ .
-make install
+cmake -Denable_java=ON .

If cmake complains that **jni could not be found**, you need to tell it where
JNI header files are located. the following command should tell you:
\subsubsection bindings_binding_java_use How to use Simgrid-java
To execute the examples you need to add the path where you installed
-the generated `libSG_java` library (`<build_dir>/lib`) and `libsimgrid`
-(`$SIMGRID_ROOT/lib`) into the `LD_LIBRARY_PATH`.
+the generated `libSG_java` and `libsimgrid` libraries
+into the `LD_LIBRARY_PATH`.
Be careful on Mac, this variable is called `DYLD_LIBRARY_PATH` and not
`LD_LIBRARY_PATH`.
