Let me know, I can also try some things. I have been able at least to 
compile and run cholmod on 18.04 with simple c++ programs.
I wanted to just replicate a hello-cholmod function inside yade to see 
if the problems come from some specific compilation/link options used 
for yade compilation.

Yes beggining of March IIRC.

I was expecting that, thanks.

Indeed, it used to work.
