Question about running ctest based on the instructions in HACKING.md

This is mostly from the top of my head as I can't test everything right now, but you have some options:

1. in a conda environment, run the install script e.g. install.sh from the competition (don't forget to update the revisions to get the latest version of operon). you can remove pyoperon from that script if it's not needed.
2. using nix, as per BUILDING.md will get you a dev shell where you can configure and build operon.
   one can also do to get a built version. a result symlink will then point to its location in the nix store.

   nix build github:heal-research/operon/cpp20 --no-write-lock-file
   

   same as above but inside docker:

   docker run -ti --rm docker.nix-community.org/nixpkgs/nix-flakes nix shell github:heal-research/operon/cpp20 --no-write-lock-file
   

3. vcpkg - this might not work as I suspect some of the port files might be outdated, but instructions are present in BUILDING.md

Feel free to reopen this and I'll do my best to help.

Hi,

Sorry, ctest integration is not complete yet. If you want to check the available presents, please see cmake --list-presets.
If you do want to run the available unit tests, there are available in a separate project. Just pass -Doperon_DEVELOPER_MODE=ON to cmake and it will get build in build/test/operon-test.

hi @foolnotion, @msnliu is working with me to install and test operon. Thanks for your quick response. Could you recommend a simple starting example we can follow for running the CLI version?

[lacava]

thanks @foolnotion ! we went the vcpkg route, but will switch to 1 or 2 and see how it goes.

Happy to help! For option 1, the cmake flag -DBUILD_CLI_PROGRAMS=OFF needs to be -DBUILD_CLI_PROGRAMS=ON. eve, vstat, operon revisions need to be the latest ones. You probably also want to pass -DCMAKE_CXX_FLAGS=-march=x86-64-v3 or something similar, in order to get the best performance.
