This is a mistake that I I'm not sure can be fixed since you installed a binary package.

Well, I generated the jessie_why.vo ( I took it from why lib) and I added it to the same folder of sample.v.

Please try again with why --coq-v8 > Well, I really don't know what to do! My problem is to generated the Coq file using the Jessie-plugin. As far as I understood, the problem is in Why and not in Frama-C, but I don't know how to solve it. > > It's a combination of problems: - Frama-C binary package should have been compiled with coq V8 support - Why should redetect properly the coq version after installation Hope this helps, - Claude -- Claude March? | tel: +33 1 72 92 59 69 INRIA Saclay - ?le-de-France | mobile: +33 6 33 14 57 93 Parc Orsay Universit? | fax: +33 1 74 85 42 29 4, rue Jacques Monod - B?timent N | http://www.lri.fr/~marche/ F-91893 ORSAY Cedex |
