[Gnuplot-info] generate .eps file in %!PS-Adobe-3.0 EPSF-3.0 format?

[Jon <dev...@gm...>]

I am trying to include .eps file into latex. I generated .eps file using
gnuplot. The problem is that it cannot be successfully compiled, complaining
that

! LaTeX Error: Unknown graphics extension: .eps

However, this does not happen for .eps files created from xgrace. I tried to
compare the difference between these two and find that it could be because
the .eps is created in xgrace has higher version number than it created from
gnuplot 4.2.

I am wondering whether this is the actual cause of the problem. If the case,
is it possible to upgrade gnuplot to generate .eps files with higher
version.

Thanks,

John
