Downloading lammps using git

[kaustubhjsawant]

Hello,

I am trying to build ssages with lammps using the following commands :

mkdir build && cd build
cmake -DLAMMPS=YES ..
make

However as of Jan. 11th, 2022, Git has changed its security protocol. (https://github.blog/2021-09-01-improving-git-protocol-security-github/#no-more-unauthenticated-git). Therefore I am getting the following error :

Error

Thank you, Kaustubh

GitHub deprecated the use of git:// URLs. The functionality should be fixed if you replace it with https:// in the file hooks/lammps/CMakeLists.txt. All other repositories already use the https:// protocol.

The following command will update the file appropriately:

sed -i "s/git:/https:/g" hooks/lammps/CMakeLists.txt
