Re: west: multiple local west project installations

Carles Cufi

I am not quite sure I understand David.


“west init” initializes an installation. It creates a top-level folder which then contains a .west/ subfolder and a bunch of other folders that correspond to the manifest repo and west projects.

Once you are inside that installation you cannot really refer to another installation, but you *can* switch the path to the manifest repository by using your ~/.westconfig or the “west config” command. Say you have a zephyrproject/ top-level installation folder and there’s a zephyr/ folder inside it, at the same level as the .west/ folder. Say also that you have a myrepo/ folder at the same folder level that contains a myrepo/west.yml with your own manifest. Then you can do:


west config manifest.path zephyr (&& west update)

west config manifest.path myrepo (&& west update)


to switch between manifest repos while remaining in a single installation.

no. I want to initialize a second Zephyr project area in parallel. So for example:

Hi David:

I'm not sure if I understand your question correctly.

Do you mean that you  created "zephyrproject_2" under "/home/dleach/work/zephyrproject" and run "west init"? If so, I don't think you should create "zephyrproject_2" like this. You should create it in another directory, rather than "/home/dleach/work/zephyrproject".

Can I use west to initialize multiple working directories?


I’m experimenting with adding a module and I wanted to a setup so I created a ‘zephyrproject_2’ directory and ran a ‘west init’ command with some additional parameters to use the west.yaml of my url/branch but it returns an error which leads me to think a system can only have one installation:


FATAL ERROR: already in an installation (/home/dleach/work/zephyrproject), aborting
