> <\body> \; As the minimal distribution provides only the basic data structure, sooner or latter one will like to extend it with more advanced tools. Let us show, as an example, how the package which provides extended arithmetic, can be added to the environment. Hereafter, we assume that we are in the folder and that the source code is available in . We also assume that the commands and are available (see how to install a ). <\shell-fragment> mmxmake ../minimix +p numerix The configuration files are updated accordingly. This package depends on two external libraries: <\itemize-dot> |http://gmplib.org/> for integer and rational numbers, |http://www.mpfr.org/> for floating point numbers. If they are not installed globally, the option can be set to download and build them:\ <\shell-fragment> cmake ../minimix -DEXTERNAL=ON Then the new libraries can now be built: <\shell-fragment> make The library can now be loaded in the interpreter : <\session|mathemagix|default> <\input> <|input> use "numerix" <\unfolded-io> <|unfolded-io> 122333344555^56 <|unfolded-io> <\input> <|input> \; The other packages of the distribution can be added in a similar way, respecting the dependencies. A list of packages is available . For more information on how to update packages, see . \; <\initial> <\collection>
