Source build checking out submodules on branch?

[andrjohns]

Hello! When StanHeaders is being built, the source build is failing in a way that I can only replicate if the submodules aren't also recursively checked out to the chosen branch (experimental).

Is it possible that the source build isn't handling submodules correctly? Is there a way I can replicate the build locally to debug?

Universe config here for reference.

Thanks!

We can't change the default to always checkout all submodules, because that breaks or slows down other projects.

One solution is to add a .prepare or bootstrap.R script to your project, in which you initiate the required submodules. These scripts will be executed after the checkout: https://github.com/r-universe-org/build-source/blob/master/entrypoint.sh#L45-L51

Brilliant thanks, that did the trick!

If it's possible, would you be able to trigger a re-run for the rstan build action? It should build now (or at least fail differently) with the newly-built StanHeaders.

Thanks again!

Ah just saw the button for triggering the rebuild myself, sorry for the noise
