Re: [Gretl-devel] gretlcli termination (crash?) with gnuplot error

Hi,
the following happened when running the awm.inp example file from the SVAR
addon on a console-only installation (Linux), within a "gretlcli" session via
gretl's 'run' command.
The awm.inp script must fail because it tries to send stuff to gnuplot with
the "display" option. That's understood. Here is some error output:
gnuplot stderr: '01:48:52 PM: Error: Unable to initialize GTK+, is DISPLAY
set properly?
Failed to initialize wxWidgets.
'
Failed command: 'gnuplot -persist
"/home/gretlcheck/.gretl/gpttmp.plt"'
However, after that I don't get back to the gretlcli prompt ("?"), but
instead gretl(cli) terminates and I'm at the shell prompt. And I think that's
not right.
I've experimented with running a script containing deliberate errors
under "run" in gretlcli and mostly you get the interactive prompt
back. An error in calling gnuplot (or maybe an error in calling any
external program?) seems to be the exception. I'll see what I can find
out about this.
