Hi to everybody,
A few days ago I posted a question in the plplot "Help" discussion
forum about a the development of a new driver for GNUstep
(http://sourceforge.net/forum/forum.php?thread_id=2185650&forum_id=8607).
In the last days I investigated a bit more the problem.
I was thinking of implementing the GNUstep driver within a test
application which links to the plain `plplot' library as it is already
installed by my Ubuntu package manager (libplplot-dev). In this way I
would not mess up with plplot sources while I test my code.
I have thought about two possible ways to do this, but I do not know if
they are feasible.
The first (and best) alternative would be to have some functions which
allow to register a new driver within the main program. Something like
the following:
int main ()
{
/* Initialize the hypotetical `pldriver_info' structure properly */
pldriver_info * new_driver = create_driver ();
/* Register the driver so that plplot knows about it */
plregister_driver ("mydriver", new_driver_info);
/* Set `mydriver' as the default driver for this session */
plsdev ("mydriver");
plinit ();
/* start using plplot with the custom driver */
}
However, the manual does not report the existence of such functions
(although they would be very useful, IMHO).
The second idea is less elegant but perhaps more likely to be
applicable: using dynamic drivers. Creating a "mydriver.so" and a
"mydriver.rc" file into the /usr/lib/plplot5.8.0/driversd/ directory
would be enough for plplot to recognize my new driver? Do you suggest
this approach?
Thank you very much and best regards,
Maurizio Tomasi.
