Submodule don't initialize properly

Remove the 1 after --depth to make it work for newly cloned repos.

Edit: The removal of 1 after depth doesn't seem to solve it. I had to remove it completely and live with the long clone time of linux's git.

I tried to make a fallback to full clone for older git versions that don't support shallow clone at: https://github.com/cirosantilli/linux-kernel-module-cheat/blob/ae9bbf9aa641706dc618a961839fd9f4705d2281/configure#L27 but I can't test it properly since I don't have the older gits.

What happens to you exactly? Does the fallback get run, or does something fail? What is the last line that gets run, and what is the stdout?

It looks exactly like the issues you mentioned. The git submodule only get the latest ref (of the master branch) and don't pull in the commit coupled with this repo. With the result that the commit that wants to be pulled in doesn't exist in the local git history.

Stdout:

Submodule 'buildroot' (https://github.com/buildroot/buildroot) registered for path 'buildroot'
Submodule 'linux' (https://github.com/cirosantilli/linux) registered for path 'linux'
Submodule 'qemu' (https://github.com/cirosantilli/qemu) registered for path 'qemu'

If I run git log --oneline in the directory buildroot I get:

7c384c3 qt5tools: fix typo in <pkg>_SOURCE

And that's all the history it knows, so it pulls in 1 depth as specified but it is the origin/master ref not the one referenced by the submodule. Hope this helps with finding a solution.
