Thank you for the mini-driver and correcting my syntax. (Updated the repo
<https://github.com/akigupta131/ascend-steam-reformation/commit/1a0de9f3e508caadeb91c7c12ba793d55f4ed0df>
)
Unfortunately while I am trying to run that as you suggested, I am getting:-
PROGRAM ERROR: ascend/solver/solver.c:138:slv_lookup_client: Invalid engine
name 'QRSlv'
runqrslv: ascend/runqrslv.c:110: main: Assertion `qrslv_index != -1' failed.
Aborted (core dumped)
Also looking at the bug http://ascend4.org/b564, It's quite possible that
maybe the case. I am using Ubuntu 14.04 LTS on 64 bit system. Good luck
with the bug. I'm also trying to find some solution.
I'm looking for a 32 bit system. I'll soon start working on it. And get
back to you in case of any progress.
Thanks for all the help :)
