yes!

Well, I see it links too, looking down the log (it seemed to be
compiling with gcc on a Ubuntu system). Does it/can it install and run
on the system too? One problem is that Denemo does not have proper
separation to enable it to run without its GUI (the draw.c in particular
has side effects on the data, this is the reason for the drawing done
with cairo context set to NULL). So running without an actual display
could be problematic.

It is very easy to write tests nowadays, you can just pass a scheme
script on the command line...

I didn't delve into what you have done Eloi ... are you using gub?

very much.

are they on a branch at the moment?
