I have a problem to get jessie3 on frama-c neon working (see below).
It claims that it could not find z3 solver (but its installed, removing prover z3 from ~/.why3.conf does also not help.

Any ideas whats wrong in my setup?

My setup:
- Ubuntu 14.04
- Z3 [version 4.3.1 - 64 bit] (manuell kompiliert)
- alt-ergo 0.95.2-1build1
- coq 8.4pl3dfsg-1
- coq-theories 8.4pl3dfsg-1
- Why3 platform, version 0.83 (build date: Mon Aug 11 18:23:24 CEST 2014) (manuell kompiliert)
- /usr/local/bin/frama-c --version
Version: Neon-20140301
Compilation date: Sat Aug 9 14:16:12 CEST 2014
