Issue building

[hnisonoff]

Hi! I am very interested in using your solver!

I am running into the following error:
fatal error: cub/detail/device_synchronize.cuh: No such file or directory 36 | #include <cub/detail/device_synchronize.cuh>

I am using CUDA 11.4

It looks like I don't have any cub/detail/ directory:

Do you have any advice on how to proceed? I am unable to install different CUDA versions on this machine. Thanks!

Have you followed the instructions to install the solver, in particular have you exactly typed git submodule update --remote --recursive --init? Please try this out on a fresh checkout of the repo.

[hnisonoff]

When I run that command in a new checkout I get the following:

fatal: Needed a single revision
Unable to find current origin/master revision in submodule path 'external/CLI11'

All of the directories in external are also empty.

[hnisonoff]

It looks like part of the reason the command failed is because the .gitmodule file had to be edited to point to the "main" branch rather than the default "master" which doesn't exist for some repos. I was still unable to make progress though.

In issue #13 (#13) i describe how you can solve it. Basically you need to

1. navigate with terminal to <bdd_root>/external/thrust/dependencies/cub/
2. Inside the folder of step 1) do $ git checkout main and git pull
3. try building the project once again :)

I think the error is exactly what you describe and might come from that "cub" project switched branch names from master to main.

Whenever you will re-invoke in <bdd_root> the command git submodule update --remote --recursive --init you'll likely have to follow my "solution" again :)

Thanks to @paul0noah the issue should now be fixed. Please reopen if it is not.
