Build error when trying to make all

[duguorong009]

Description

It is needed to update the git submodule url of labrador in .gitmodules

Context

When I try to follow the guideline in paper and build LaZer using make all, I get the error.
In fact, I get the following error when I run git submodule update cmd.

Cloning into '../lazer/src/labrador'...
ERROR: Repository not found.
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.
fatal: clone of '[email protected]:gregorseiler/labrador.git' into submodule path '../lazer/src/labrador' failed

Hi, I found a possible link to the Labrador library repository that might solve the issue.
It could be useful for future updates or as an alternative to the current repository.
You can find it here at: https://github.com/lattice-dogs/labrador
Let me know if it’s the correct link to use.

Hey, @alby0x0c
Thanks for tip!

BTW, I already tried your idea before posting this issue.
I mean I update the .gitmodules file like following:

[submodule "src/labrador"]
  path = src/labrador
  url = https://github.com/lattice-dogs/labrador.git

Then, I try to run this commands.

git submodule init
git submodule update --recursive

I get this error.

Cloning into '.../lazer/src/labrador'...
fatal: remote error: upload-pack: not our ref af6e5d6d4aa95a9dd287a47fda1b86f054e86f3b
fatal: the remote end hung up unexpectedly
Fetched in submodule path 'src/labrador', but it did not contain af6e5d6d4aa95a9dd287a47fda1b86f054e86f3b. Direct fetching of that commit failed.

I think the author @p-steuer adds some more commits to his own fork of labrador, and uses that for this lib.
Hence, I hope he resolves the issue.

(Similar issue in #3 )

The labrador submodule accidentally pointed to a private repo.
This is fixed with commit 3e33453.
