<H3>Troubleshooting the configuration process</H3>
If the configure script fails it should give you some feedback about
what it can't find on your system. One of the most common problems
is not being able to find library files.
<P>Two common things to check for are:
<P><OL><LI>Check the value of the <CODE>LD_LIBRARY_PATH</CODE> environment variable. This
is used to tell your system where to look for libraries which are
not installed in <CODE>/usr/lib</CODE>. Quite often packages which you install
yourself will put library files in <CODE>/usr/local/lib</CODE> by default. If
<CODE>LD_LIBRARY_PATH</CODE> doesn't point to this directory (or wherever else
the library files are installed) then programs which depend on these
libraries at run time will not be able to find them.
<P>To find out the value type:
<P><PRE>
echo $LD_LIBRARY_PATH
</PRE>
<P>If the value is empty or doesn't contain <CODE>/usr/local/lib</CODE> or any of
the paths where your libraries are located in its colon separated list of paths
then you must amend it so that it does. To do this first find out which shell you
use by typing:
<P><PRE>
echo $SHELL
</PRE>
<P>If you're using the <CODE>bash</CODE> shell see section <A HREF="UserManual_13.html">*</A>
below for details of how to amend the value. If you're using the <CODE>tcsh</CODE>
shell see section <A HREF="UserManual_14.html">*</A>.
<P><LI>If you install Mesa, GLUT or audiofile via RPM binary distributions
check that you have the appropriate <EM>development</EM> packages installed
also. These include:
<P><UL><LI><CODE>audiofile-devel-0.1.6-*</CODE>
<LI><CODE>Mesa-devel-3.0.*</CODE>
<LI><CODE>Mesa-glut-devel-3.0.*</CODE>
</UL>
<P>These packages provide header files and symbolic links to the libraries
(e.g. <CODE>libaudiofile.so</CODE> linked to <CODE>libaudiofile.so.0.0</CODE>).
Without these packages the libraries themselves may be installed
but you still won't be able to compile and link programs with them.
</OL>
<P>If, after reading this section you are still baffled then take a look
at the next section too, since there is a further tool you can use to
help diagnose problems.
