Gpsim and invisible nodes

[Phil-22]

Thank you for reading this.

If I connect, say, a single switch to a port pin then the connection is
visible, as it should be. However, adding further nodes causes all nodes  to
become invisible. Is this another gtk-extra bug and is a patch available to
fix it?

I've added two patches to gtk-extra that were designed to prevent Gpsim
crashing but I haven't found any mention of any further patches.

Invisible in what sense? Do you mean the black lines on the breadboard vanish? If so, this is merely a very long-standing quirk of the breadboard (which is STILL marked as being in development and untrusted). The "trace all" button will restore most, but not always all, until you change something else. The connections still exist, though; it's only the black lines that vanish.

To be honest, I think the developers[1] have been treating this as very low priority, since the breadboard is not actually that useful. Indeed, I tend to leave it on another virtual screen and only switch to it very occasionally.

There's been some development going on in SVN recently, but not on the breadboard. We don't tend to announce patches - if somebody submits one via this list then you might see it, otherwise you need to check the bug tracker (which is often out of date on status so read the comments) or the SVN log.

Also, GPSim questions are often best directed to the GPSim mailing list rather than this more general PIC list.

Cheers,
Rob

Yes, a single connection is always visible but multiple connections are never
visible. I find that having the breadboard display visible connections is
handy since I don't always have the hardware to experiment with. I live in a
remote area and mail ordering small quantities is difficult.

Thanks for that tip as well Rob. Both of the Piklab and Gpsim discussion
forums at Sourceforge have a very low traffic rate and the likelihood of
having a question answered is also disappointingly very low. I'll have
another look for a suitable mailing list.

Hi All,

question directed to Phil,
did you have any futher luck getting gpsim to work under piklab?

I have been using piklab (SVN co 2906) successfully with a CCS compiler,
and ICD2 device. But today I decided to add gpsim to the toolbox.
I did a SVN checkout today, and set about building it. I'm using Ubuntu 8.04
with all updates, and had to add..
bison
flex
libreadline5-dev
libpopt-dev
libgtkextra-x11-2.0-1
libgtkextra-x11-2.0-dev
this allowed a build to finish, and install.
but now I have the same error you had 2 months ago.
'Could not detect supported deivces for "GPSim"'

Is anyone else successfully running gpsim under the piklab IDE?

regards
Andrew
