Error building software stack

Cobain

Hi,

I have been trying to build the Morello software stack using the 1.3 release user-guide.rst and have not been able to get it to build.

The error I have been getting is:  

Submodule path 'llvm': checked out '47853ef78a113576a9f4e927fe46409a88f1c503'

Using the following command:

Have I made a mistake somewhere or is there a problem with the repository?

    Hi Cobain,

    This error:

    fatal: A branch named 'morello/release' already exists.

    is a known issue with the current releases of morello-aarch64. It should however be harmless if you haven't changed the branch manually in morello-aarch64/morello/musl, and it shouldn't stop the build either. Is this what you are observing?

    Please note that there is a more serious issue when using the 1.3 or 1.4 release, causing Musl to fail to build (this happens after the checkout error you are referring to). This was fixed in minor releases 1.3.1 and 1.4.1. Make sure to switch to either of these releases; as a general rule you are encouraged to use the latest release, that is 1.4.1.

    Hope that helps,

    Kevin

    Thanks Kevin, will definitely try that.

    Cobain was using 1.3, as the guide on the Arm website here links directly to the 1.3 documentation here and I guess he took it on trust that it was current.

    Maybe we could add a note in the top-level guide to indicate that the direct link isn't necessarily current, and advising users to check for updates?

    Thanks again.
