Editing Advanced Installation (section)

==Dependencies==
Some platforms feature complete lists of dependencies. See [[Advanced Installation#Platform-specific installation advice | Platform-specific installation advice]] for details.
===C++ API===
A C++ compiler. SCons is smart and will try to find it for you. If it does not work specify the path to your compiler in the <tt>CXX</tt> environment variable (can be passed as an option to the configuration script, like the <tt>API</tt> one).
===F77 API===
A Fortran 77 compiler. If SCons does not find one, then you can either specify its path through the <tt>F77</tt> variable, or if the executable is in your path, add its name to the list of F77 compilers in <tt>RSFSRC/configure.py</tt> .
===F90 API===
Same as for Fortran 77 &ndash; just substitute <tt>F90</tt>. If using the <tt>gfortran</tt> compiler, make sure to get [http://gcc.gnu.org/wiki/GFortranBinaries the latest version]. If you have more than one compiler installed on your system, specify the desired one at configuration time:
<bash>
./configure API=f90 F90=/path/to/preferred/compiler
</bash>

===Java API===
There are two styles of API, old (1.0 release and previous) and new. The two APIs are not compatible with each other.

The "old" interface requires the Mines Java Toolkit for fast Java file IO. The Mines JTK, is an open-source Java package that can be downloaded from [http://inside.mines.edu/~dhale/jtk/ Mines JTK]. Currently, the "old" interface will also build alongside the new one if the MINESJTK environment variable exists, and can be used as was previously.

To install the new API, you need the (Oracle) JDK. Set your JAVA_HOME environment variable to the location of the jdk (on Ubuntu 10.04 this is: /usr/lib/jvm/java-6-openjdk), then reconfigure (./configure API=java ...) and reinstall.  

Ignore the SWIG warnings (there are lots). 

Make sure to set your LD_LIBRARY_PATH to $RSFROOT/lib .

If you want to include additional Java packages, you can set them using your shell's CLASSPATH variable.  This environment variable is now automatically passed onto all Java classes in SCons.

The installation can be tested using the example demonstrating the new API in api/java/test .

===Matlab API===
Besides Matlab itself, you need Mex, which compiles C code into regular Matlab functions. Use the <tt>MATLAB</tt> and <tt>MEX</tt> environment variables to specify their paths if they are installed, but not found.
===Octave API===
The Octave function compiler (<tt>mkoctfile</tt>) is sometimes bundled in a separate package, so it may be missing from the Octave installation.

===Python API===
This API requires [http://www.swig.org/ SWIG], [http://numpy.scipy.org/ numpy] and the Python development kit. Numpy requires Python 2.4 or newer (i.e. RHEL 5 or newer). However, these dependencies are unnecessary for the common case when Python is just used as [http://en.wikipedia.org/wiki/Glue_language glue] to create chains of programs, and it only needs to read the RSF header, and not the binary. To allow Python [http://en.wikipedia.org/wiki/Meta-programs metaprograms] in madagascar to function, and programming in this style to be done, a fallback development kit implementing only the header-related functionality will be installed in the lack of these dependencies.

===Python modules in user space===
Python is an evolving language. Many large systems have old versions for stability reasons, and administrators of such large systems tend to not install all software users may wish, and to not allow access to rpm either. To install a module in your user space, download the tarball, unzip it, cd into the directory and run: 

<pre>python setup.py install --prefix=/path/to/your/place</pre>

The installer will create a subdirectory named <tt>lib</tt>, or <tt>lib64</tt> under the directory above. These <tt>lib*</tt> dirs will have a directory named <tt>python</tt>, or <tt>python2.3</tt> for example, and those will have a subdirectory named <tt>site-packages</tt>. Add all paths to these <tt>site-packages</tt> subdirectories in your <tt>PYTHONPATH</tt> environment variable. Some (<tt>numpy</tt>) may create a <tt>bin</tt> directory that needs to be added to <tt>PATH</tt>.
