For installation instructions see Chapter <a href="badlink:ref:Installing a GAP Package">Installing a GAP Package</a> in the <font face="Gill Sans,Helvetica,Arial">GAP</font> reference manual. Normally you will unpack the archive in the <code>pkg</code> directory of your <font face="Gill Sans,Helvetica,Arial">GAP</font> version by typing: <p> <pre> bash> tar xfz radiroot.tar.gz # for the gzipped tar-archive </pre> <p> <p> <h2><a name="SECT002">4.2 Loading and Testing the Package</a></h2> <p><p> To use the <font face="Gill Sans,Helvetica,Arial">Radiroot</font> package you have to request it explicitly. This is done by calling <p> <pre> gap> LoadPackage("radiroot"); ----------------------------------------------------------------------------- Loading RadiRoot 2.4 (Roots of a Polynomial as Radicals) by Andreas Distler (a.distler@tu-bs.de). ----------------------------------------------------------------------------- true </pre> <p> The <code>LoadPackage</code> command is described in Section <a href="badlink:ref:LoadPackage">LoadPackage</a> in the <font face="Gill Sans,Helvetica,Arial">GAP</font> reference manual. <p> If you want to load the <font face="Gill Sans,Helvetica,Arial">Radiroot</font> package by default, you can put the <code>LoadPackage</code> command into your <code>.gaprc</code> file (see Section <a href="badlink:ref:The .gaprc file">The .gaprc file</a> in the <font face="Gill Sans,Helvetica,Arial">GAP</font> reference manual). <p> Once the package is loaded, it is possible to check the correct installation by running the test suite of the package with the command <p> <pre> gap> ReadPackage( "radiroot", "tst/testall.g" ); </pre> <p> <p> <h2><a name="SECT003">4.3 Additional Requirements</a></h2> <p><p> To use <font face="Gill Sans,Helvetica,Arial">Radiroot</font> the package <font face="Gill Sans,Helvetica,Arial">Alnuth</font> 2.2.2 or higher has to be loaded with its full functionality available. This means in particular that KANT <a href="biblio.htm#KANT"><cite>KANT</cite></a> in version 2.4 or 2.5 needs to be installed. <p> In the standard mode a dvi file is created to display the roots of a polynomial. As default the package uses the command <code>latex</code> searched for in your system programs to create the dvi file and the command <code>xdvi</code> to start the dvi viewer. If you can not use this settings you will have to change the function <code>RR_Display</code> in the file <code>Strings.gi</code> in the subdirectory <code>lib</code> of the package. <p> <p> [<a href = "chapters.htm">Up</a>] [<a href ="CHAP003.htm">Previous</a>] [<a href = "theindex.htm">Index</a>] <P> <address>Radiroot manual<br>January 2008 </address></body></html>
