Re: [Plplot-general] Does plplot have an equivalent of PGPLOT's /xserve device?

[Thomas M. <t.r...@wa...>]

yes of course: here is a cut-and-paste:

cd pgplot_build [the directory I created for building]

make xwin
[  0%] Built target plhershey-unicode-gen
[  7%] Built target plhershey-unicode.h_built
[  7%] Built target csirocsa
[ 15%] Built target deltaT-gen
[ 15%] Built target deltaT.h_built
[ 15%] Built target tai-utc-gen
[ 15%] Built target tai-utc.h_built
[ 15%] Built target qsastime
[ 92%] Built target plplotd
[100%] Built target xwin

make _plplotcmodule_fixed
make: *** No rule to make target `_plplotcmodule_fixed'.  Stop.
