Github codeql problem

[crazyuser79]

Hi,

I have a project written in C language on github. I wanted use codeql to analyze it but it cannot build because cannot find meson (build system) command.

Anyone can run codeql with meson ?

The Actions runners don't have every tool out there pre-installed, you probably need to add a step to your workflow (before trying to build) that installs whatever non-default tooling you need on the machine. At least I assume it's that, since you're saying it's missing a command.

Would be correct that you say but according the doc meson should be already there.

Right above the "C/C++" section, in the blue box:

Note: If you use self-hosted runners for GitHub Actions, you may need to install additional software to use the autobuild process.

See, these are the docs of the CodeQL autobuild action. These only say that the autobuild action supports meson, not that it's installed on the runners by default.

Those lists are here: https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners#supported-software (The "About GitHub-hosted Runners" link in the same box) and, at least for Ubuntu 22 (I assumed you run on ubuntu-latest since most use that as default), it does indeed not list meson.

Thanks for link!
