I have problems with ps device. When I use the following command including "device,/close",
I get the error,
% Warning: getlogin() failed!
When I remove the "device,/close" line and write,
% Warning: multi-page PostScript not supported yet (FIXME!)
Either way I am not getting the desired ps file, an empty ps file is created. Please help….
By the way I am using Ubuntu 12.04 LTS.
First time I read report about this "getlogin()", to be checked !
pb with blanck PS is known :(
if you are compiling by yourself GDL, it would be better to desactive libps (-without-pslib)
on U 12.04, I would advice to desactivate IM and switch to GM
We hope to have very soon a revised version of some Graphical parts, thanks to Gilles !
"Warning: getlogin() failed!" is just a warning and tells you that GDL was not able to retrieve your unix username to be put into the PS file in a header comment. This happens e.g. when using the screen terminal, and it is handled by gdl. That's not an error - just a warning.
"% Warning: multi-page PostScript not supported yet (FIXME!)" is related with the fact that pslib does not handle yet multi-page postscripts. Using "ENCAPSULATED" keyword to device disables use of pslib so you can try this way. You should then get a multi-page eps (which is not PostScript standard compliant, but that what's the plplot library outputs).
