`make prove` fails with `gnatprove: unrecognized option '--checks-as-errors=on'`

[mgrojo]

Invocations to gnatprove seem to require a newer version compared to the one available in Alire.

When running make prove

/home/mgr/src/github/mgrojo/coap_spark/tools/RecordFlux/.venv.poetry/bin/poetry run make -C tests/spark prove
make[1]: se entra en el directorio '/home/mgr/src/github/mgrojo/coap_spark/tools/RecordFlux/tests/spark'
/home/mgr/src/github/mgrojo/coap_spark/tools/RecordFlux/tools/gnatprove -Ptest -Xtest=
gnatprove: unrecognized option '--checks-as-errors=on'
try "gnatprove --help" for more information.
make[1]: *** [Makefile:32: prove] Error 1
make[1]: se sale del directorio '/home/mgr/src/github/mgrojo/coap_spark/tools/RecordFlux/tests/spark'
make: *** [Makefile:494: prove_tests] Error 2

After looking at https://github.com/AdaCore/spark2014/commit/3e33794eb73f0fca408dccb48148e6f1492f8bbd I changed --checks-as-errors=on to --checks-as-errors. But there are more incompatibilities:

gnatprove: unrecognized option '--function-sandboxing=off'

gnatprove on PATH is version 14.1.1 as installed by Alire. RecordFlux is v0.24.0.

Hi @mgrojo,

thank you for your report!

As you have noticed, we do not officially support the Alire version of gnatprove for developing RecordFlux. SPARK Pro is a prerequisite for that. Consequently, the internal testsuite is run only with the Pro tools.

That being said, you may still be able to verify most of the code you generate with RecordFlux using the toolchain from Alire. Are you sure you're really using the most recent version? When adding gnatprove to the install_gnat target, removing "colibri" from the list of provers in tests/spark/test.gpr and then using $ eval make_printenv_gnat to setup your environment you should be able to get the proofs started without fatal errors. Note, that there may be a few unproven verification conditions, though.

No, it seems I wasn't. Thanks.

✓ Installation targets fully solved
error: Release gnatprove=14.1.1 has another version already installed:
error:    gnatprove=12.1.1:
error:    Releases installing executables can be installed only once:
error:    Forcing this install will overwrite the release already installed. (This error can be overridden with --force.)

After forcing the update and removing "colibri", I got what I think you expected.

I'll close this as it has been clarified. Thanks.
