In this case you can unpack XGAP in any other location within a ``pkg'' directory with the <var>unzoo</var> command as described above. Let us call this directory ``pkg'' for the moment. You get an ``xgap'' subdirectory with all the files of XGAP in it. You follow the standard procedure with two exceptions: <p> Before you can configure and compile XGAP you need a symbolic link ``cnf'' which is in the directory where ``pkg'' is and points to the ``cnf'' directory in the main <font face="Gill Sans,Helvetica,Arial">GAP</font> directory. You can install this link directly after unzooing by (remember: you are in the ``pkg'' directory!): <p> <pre> ln -s /usr/local/lib/gap4/cnf .. </pre> <p> if ``/usr/local/lib/gap4'' is the location of the main <font face="Gill Sans,Helvetica,Arial">GAP</font> installation. <p> You can find out where the main <font face="Gill Sans,Helvetica,Arial">GAP</font>4 installation is by starting <font face="Gill Sans,Helvetica,Arial">GAP</font> as usual and looking at the variable <code>GAP_ROOT_PATHS</code> within <font face="Gill Sans,Helvetica,Arial">GAP</font>. <p> Note that you have to edit the startup script ``xgap.sh'' (see previous section) to adjust the paths for ``XGAP_DIR'' and ``GAP_DIR'', and possibly the name of the <font face="Gill Sans,Helvetica,Arial">GAP</font> executable ``GAP_PRG''. Enter your <font face="Gill Sans,Helvetica,Arial">GAP</font> installation directory for the variable ``GAP_DIR'' and the name of the directory that contains ``pkg'' for the variable ``XGAP_DIR''. The variable ``GAP_PRG'' has to contain the path to the <font face="Gill Sans,Helvetica,Arial">GAP</font> executable relative to the ``bin'' subdirectory of the main <font face="Gill Sans,Helvetica,Arial">GAP</font> installation. In most cases this value will already be correct. Note however that if <font face="Gill Sans,Helvetica,Arial">GAP</font> and XGAP are compiled on different machines, then it is possible that these directory names differ for the <font face="Gill Sans,Helvetica,Arial">GAP</font> and XGAP executables respectively. <p> The script will automatically launch <font face="Gill Sans,Helvetica,Arial">GAP</font> with two directories as library path such that all <font face="Gill Sans,Helvetica,Arial">GAP</font> and XGAP libraries will be found. <p> <p> [<a href = "C003S000.htm">Up</a>] [<a href ="C003S005.htm">Previous</a>] [<a href ="C004S000.htm">Next</a>] [<a href = "theindex.htm">Index</a>] <P> <address>xgap manual<br>Mai 2003 </address></body></html>
