Re: [Plplot-general] png plots

[Alan W. I. <ir...@be...>]

What was the output from configure?  Your problem is almost sure to be due
to an old or non-existent header or library for one/some of libgd, libpng,
or zlib.  --enable-png has no effect on configure if correct versions of
these necessary libraries/headers are not installed in the usual place. What
versions of all of those have you installed?  Where have you installed them
on your system?  Have you included the headers (usually in a package with
-dev or -devel in the name) with your installation of the libraries? What
Unix/Linux system do you have?

I need these details in order to help you.
