[Gnuplot-info] libgd and libpng question

[Smith, R. H <Rya...@ph...>]

I'm trying to output my graphs in png format, but am not sure how to use the
libgd and libpng libraries.  Do they need to be installed before compiling
gnuplot, or does gnuplot use them at run time?  And where would I
change/include the path to the libraries so that gnuplot can use them?
I've installed these libraries in a non-standard folder
(/opt/src/sftw/../../../lib/), which is the cause of my problem, I know.
But that's the way it needs to be.

Thanks!
