running it manually in CLI is ok; running attached script produces:

dhp at moon_gen_2:~/documents/programmation/rpl$ ./ewample_draw_graphic.rpl

Any way, nothing come out; no popup, no extra window.

I attach the created eps (1195 bytes, content is white).

I have installed gv and redo all steps above, same result.

After checking deep logs, rpl was build with gnuplot.

Logs mention:

checking for gv... no
configure: WARNING: Cannot find gv! You may install it.

is this the problem ?

In fact, it was a stupid question. La nuit porte conseil :)
