RHEL8 Install

[lwli11]

Please feel free to ignore this if CN is not intended to support RHEL.

Installing on CN works according to: https://github.com/rems-project/cerberus/blob/master/backend/cn/INSTALL.md until 'make install'.

$ make install [DUNE] cerberus [DUNE] install cerberus Error: The mandir installation directory is unknown. Hint: It can be specified with '--prefix' or by setting '--mandir' make: *** [Makefile:294: install] Error 1

Would running CN in a docker container work for you? See https://github.com/rems-project/cerberus?tab=readme-ov-file#docker-image

[lwli11]

It should! To confirm, which of deps/release/dev-env should I pick?

$ make -f Makefile_docker targets: deps|release|dev-env

Thanks!

[podhrmic]

We have been using the release image:

make -f Makefile_docker release

Thanks! I seem to run into an issue.

I suspect this is due to too old an OCaml version. Which version of OCaml do you have? We depend on an OCaml version of at least 4.14.0 (This information was previously missing in CN's build machinery, I just added that.)

Thanks, the docker image now builds.

I also see the image: docker image ls Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg. REPOSITORY TAG IMAGE ID CREATED SIZE localhost/cerberus release 635ba847a591 19 minutes ago 2.96 GB

However, when I run the docker run command: docker run --volume PWD:/data/ cerberus:0.1 tests/tcc/00_assignment.c --pp=core bash: PWD: command not found... Similar command is: 'pwd' Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg. ? Please select an image: ▸ registry.access.redhat.com/cerberus:0.1 registry.redhat.io/cerberus:0.1 docker.io/library/cerberus:0.1

Or when I replace 'PWD' with 'pwd': docker run --volume pwd:/data/ cerberus:0.1 tests/tcc/00_assignment.c --pp=core Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg. ? Please select an image: ▸ registry.access.redhat.com/cerberus:0.1 registry.redhat.io/cerberus:0.1 docker.io/library/cerberus:0.1

@cp526 maybe this issue could be a gentle nudge to add the missing token to https://github.com/rems-project/cerberus/pull/323 and actually publish the docker image so it doesn't need to be built locally?

We have our cerberus image published in the VERSE registry, but sadly I cannot make it public yet...

I think I've found the command that works!

docker run --volume pwd:/data -it cn /data/tests/tcc/00_assignment.c Emulate Docker CLI using podman. Create /etc/containers/nodocker to quiet msg.

The docker container is now built in CI. Could we close this issue @lwli11 ?
