INSTALL Installing FreeMat

Section: Introduction and Getting Started

# Instructions

Here are the general instructions for installing FreeMat. First, follow the instructions listed below for the platform of interest. Then, run the

    -->pathtool

which brings up the path setup tool. More documentation on the GUI elements (and how to use them) will be forthcoming.

# Linux

For Linux, FreeMat is now provided as a binary installation. To install it simply download the binary using your web browser, and then unpack it

      tar xvfz FreeMat-\<VERSION_NUMBER\>-Linux-Binary.tar.gz

You can then run FreeMat directly without any additional effort

      FreeMat-\<VERSION_NUMBER\>-Linux-Binary/Contents/bin/FreeMat

will start up FreeMat as an X application. If you want to run it as a command line application (to run from within an xterm), use the `nogui` flag

      FreeMat-\<VERSION_NUMBER\>-Linux-Binary/Contents/bin/FreeMat -nogui

If you do not want FreeMat to use X at all (no graphics at all), use the `noX` flag

      FreeMat-\<VERSION_NUMBER\>-Linux-Binary/Contents/bin/FreeMat -noX

For convenience, you may want to add FreeMat to your path. The exact mechanism for doing this depends on your shell. Assume that you have unpacked `FreeMat-<VERSION_NUMBER>-Linux-Binary.tar.gz` into the directory `/home/myname`. Then if you use `csh` or its derivatives (like `tcsh`) you should add the following line to your `.cshrc` file:

      set path=($path /home/myname/FreeMat-\<VERSION_NUMBER\>-Linux/Binary/Contents/bin)

If you use `bash`, then add the following line to your `.bash_profile`

      PATH=$PATH:/home/myname/FreeMat-\<VERSION_NUMBER\>-Linux/Binary/Contents/bin

If the prebuilt binary package does not work for your Linux distribution, you will need to build FreeMat from source (see the source section below). When you have FreeMat running, you can setup your path using the `pathtool`. Note that the `FREEMAT_PATH` is no longer used by FreeMat. You must use the `pathtool` to adjust the path.

# Windows

For Windows, FreeMat is installed via a binary installer program. To use it, simply download the setup program `FreeMat-<VERSION_NUMBER>-Setup.exe`, and double click it. Follow the instructions to do the installation, then setup your path using `pathtool`.

# OS X

For Mac OS X, FreeMat is distributed as an application bundle. To install it, simply download the compressed disk image file `FreeMat-<VERSION_NUMBER>.dmg`, double click to mount the disk image, and then copy the application `FreeMat-<VERSION_NUMBER>` to some convenient place. To run FreeMat, simply double click on the application. Run `pathtool` to setup your FreeMat path.

# Code

The source code build is a little more complicated than previous versions of FreeMat. Here are the current build instructions for all platforms.

1. Build and install Qt 4.3 or later - `http://trolltech.com/developer/downloads/opensource`
2. Install g77 or gfortran (use fink for Mac OS X, use `gcc-g77` package for MinGW)
3. Download the source code `FreeMat-<VERSION_NUMBER>-src.tar.gz`.
4. Unpack the source code: `tar xvfz FreeMat-<VERSION_NUMBER>-src.tar.gz`.
5. For Windows, you will need to install MSYS as well as MINGW to build FreeMat. You will also need unzip to unpack the enclosed matio.zip archive. Alternately, you can cross-build the WIndows version of FreeMat under Linux (this is how I build it now).
6. If you are extraordinarily lucky (or prepared), you can issue the usual ./configure, then the make and make install. This is not likely to work because of the somewhat esoteric dependencies of FreeMat. The configure step will probably fail and indicate what external dependencies are still needed.
7. I assume that you are familiar with the process of installing dependencies if you are trying to build FreeMat from source.

To build a binary distributable (app bundle on the Mac, setup installer on win32, and a binary distribution on Linux), you will need to run `make package` instead of `make install`.
