[Plplot-general] problem compiling plplot with octave

[David A. <armstron@SEDSystems.ca>]

I have a (modified) Red Hat 7.3 system I am trying to install Plplot on. 
 I have Octave 2.1.40 and have compiled it with --enable-dl and 
--enable-shared.  I have configured PlPlot with --eanble-octave.  When I 
try to compile Plplot it generates many errors in the plplot_octave.cc 
file.  Below is the beginning of the error message stream.  I am using 
gcc 3.2 and I have installed matwrap.  Anyone have any idea what is 
going on here?

Regards
Dave Armstrong
