Please forgive me if this question is patronising or stupid but ... do you have all of these solvers installed and on the command-line path? CBMC does not build them in, you have to install them separately.

We should add a "solver executable not found, please install" message.
I believe #8378 will also address this one.
For the following program, I am getting different results from different solvers. Bug is unreachable in the program however some of the solvers states it as reachable.
Output for
cbmc undCBMCSmall.c --z3
ORcbmc undCBMCSmall.c --cvc3
ORcbmc undCBMCSmall.c --smt2
is as follows:Where for
cbmc undCBMCSmall.c --cvc4
ORcbmc undCBMCSmall.c --cvc5
ORcbmc undCBMCSmall.c --yices
ORcbmc undCBMCSmall.c --cprover-smt2
ORcbmc undCBMCSmall.c --boolector
ORcbmc undCBMCSmall.c --cprover-bitwuzla
ORcbmc undCBMCSmall.c --cprover-mathsat
is as follows:CBMC version: 5.80.0 (cbmc-5.80.0) Operating system: Ubuntu 16.04 / macOS Sonoma Version 14.3 Exact command line resulting in the issue: cbmc programname.c --cvc5/ --cvc3/ --cvc4 / .. other SMT solvers What behaviour did you expect: expecting same behavior from all SMT solvers as "VERIFICATION SUCCESSFUL" since the bug is unreachable What happened instead: Different solvers gives different results
