Description :
This is not a problem with this particular code, but I will include it anyways for the sake of completeness and reproducibility.
With the following C code "average.c"
/*@ ensures \result == \abs(x); / double abs(double x) { if (x >= 0) return x; else return (-x); } /@ requires 0x1p-967 <= C <= 0x1p970; @ ensures \result == \round_double(\NearestEven, (x+y)/2); @ */ double average(double C, double x, double y) { if (C <= abs(x)) return x/2+y/2; else return (x+y)/2; }
running the command
frama-c -wp -wp-model +float -wp-prover "why3:coq" -wp-print average.c produces the following output ============================================= [kernel] Parsing average.c (with preprocessing) [wp] Running WP plugin...

the line referenced in coq.drv is
"theory qed.Qed meta "realized_theory" "qed.Qed", "Qed" end
Additional Information :
Product Version: Frama-C-Chlorine-20180501 not an option in reporting tool
I reported this here because the error seems to be with the configurations files generated by frama-c in the frama-c/wp directory, but I can't be sure that the problem isn't with why3 itself. I'm still very new to using these tools.
Note: the "Builtin \NearestEven not defined" seems to be a separate bug, referenced here: https://lists.gforge.inria.fr/pipermail/frama-c-discuss/2016-July/005117.html
Steps To Reproduce :
Installed the following via OPAM
coq 8.8.0 (because 8.8.1+ reports not supported by why3) why3-coq 1.0.0 frama-c-chlorine-20180501
error persists after uninstalling and re-installing all of the above
