Hello,

Thank you for responding.  I'll send the information you asked
about below, along with a few additional comments.=20

I did a "make install" after the build was completed.  I'll mention
that I've had no problems in the past running ./gnuplot, but I went
ahead and ran it from the full path:

/tmp/external.rross/bin/gnuplot     (This is the install area)

The results were the same as before.  Also, the other terminal types
seem to be OK.  At least, when I did this, it worked.

set terminal x11
plot x*x             (parabola displayed in an X window)
splot x*x+y*y        (3-dimensional surface is displayed in X window)

I have included these items below:

- The configure parameters that I used in the build
- The link line from the log
- The output from "ldd gnuplot"

A bit more information.  The system used to compile this was SLES9.  =
This is

because we want to build it on a least common denominator, and have it =
run
successfully on other systems, like SLES10, RHEL4, RHEL5, and others.  =
The
eventual intent is to link the gnuplot binary statically (with the =
exception
of a few things like libm, libc) and distribute it along with a product =
that
calls gnuplot.  You will see many of the libraries that I compiled and
linked
in the 'ldd gnuplot' list.  Eventually we want to produce ".a" files and =

statically link the whole thing.  But first, it needs to work!

Also, the compiler used was gcc 4.0.2.  The machine native compiler, gcc
3.3.3
is not being used.  That is why some of the libraries are in
/usr/local/lib64,
(gcc 4.0.2) vs. /usr/lib64 (native installed compiler)

This is the 64 bit version.  When this works, we will also do a build =
for 32
bit.
