<H3>If you are still stuck with configuration problems</H3>
After receiving a emails from some <B>Tao</B> users who had run into
problems with the configure script I decided to write a shell script
as and aid to testing for installed libraries, their locations,
and whether or not the executables dependent on those libraries
would be able to find them. This shell script is located in the top
level directory of the distribution and is called <CODE>diagnose-lib</CODE>.
<P>Typing <CODE>diagnose-lib</CODE> without any arguments prints out the following
usage message:
<P><PRE>
Usage: diagnose-lib <libname>
Diagnose problems in finding shared libraries during
configuration of Tao
<libname> can be one of the following:
'gl', 'GL', 'glu', 'GLU', 'glut' or 'audiofile'.
</PRE>
<P>So, for example, if the configure script claims that you don't have any
OpenGL libraries installed but you are convinced that you do, type:
<P><PRE>
./diagnose-lib gl
</PRE>
to check for the GL library or
<PRE>
./diagnose-lib glu
</PRE>
for the GLU library.
<P>The <CODE>diagnose-lib</CODE> script will respond with information about whether
it can find a library of the right name, where that library is installed
and whether the executables which depend on that library will be able
to find it. It does so by searching obvious locations such as
<CODE>/usr/lib</CODE>, <CODE>/usr/local/lib</CODE> first and then searches the
directory tree rooted at your home directory. If it fails to find
the library it will abort and let you know.
<P>If on the other hand it does find a suitable candidate it then checks
to see whether either the file <CODE>/etc/ld.so.conf</CODE> or the environment
variable <CODE>LD_LIBRARY_PATH</CODE> contain the appropriate path to
find this file. These are the two principal mechanisms by which your
system locates <EM>shared objects</EM> or <EM>dynamic link libraries</EM>
at run time.
<P>If neither contain the path to this file a suitable message is printed out
and suggestions for solving the problem are given.
<P>If you find that you are still having problems after following any advice
given by the <CODE>diagnose-lib</CODE> script then please feel free to email
me at <A HREF="mailto:m.pearson@ukonline.co.uk">m.pearson@ukonline.co.uk</A>.
I will try to help out where I can.
