Error building docker image (make: *** No rule to make target 'clean'. Stop.)

[depaolim]

Hi

When I try to build the image for docker I get the following error:

make: *** No rule to make target 'clean'.  Stop.

Steps to reproduce:

uname -a
# Linux XXXX 5.15.0-102-generic #112~20.04.1-Ubuntu SMP Thu Mar 14 14:28:24 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
mkdir docker
cd docker
wget https://raw.githubusercontent.com/pgvector/pgvector/master/Dockerfile
docker build -t postgres_with_pgvector .

Any hint?
Am I missing something?

Thank you,
Marco

@depaolim it doesn't look like you pulled down the pgvector source. See the docker steps here:
https://github.com/pgvector/pgvector?tab=readme-ov-file#docker

git clone --branch v0.6.2 https://github.com/pgvector/pgvector.git; cd pgvector;docker build --build-arg PG_MAJOR=16 -t myuser/pgvector .

Great, it works! Thank you!
It seems I missed something fundamental ... :-)
