How to build GCM for Ubuntu/arm64?

[MarkCallow]

I need to get GCM working on Linux/arm64. I tried using https://github.com/git-ecosystem/git-credential-manager/blob/main/src/linux/Packaging.Linux/install-from-source.sh on my Ubuntu/arm64 system but it ended up building (?) and installing an x86-64 version. I've now cloned this repo and want to build it but I've been unable to find any build instructions. I'm completely new to dotnet.

How do I build and install GCM from the repo source? Or how else might I get an arm64 version?

Easiest is to install the GCM .NET tool https://github.com/git-ecosystem/git-credential-manager/blob/release/docs/install.md#net-tool

dotnet tool install -g git-credential-manager

You'll need to first install the .NET SDK https://learn.microsoft.com/en-us/dotnet/core/install/linux-ubuntu

Thank you @hickford. This worked. One pain point is how to install the .NET SDK. This could easily be fixed with a link on https://github.com/git-ecosystem/git-credential-manager/blob/release/docs/install.md#net-tool to instructions. Luckily I found the SDK was already installed, most likely from my having previously run install-from-source.sh, so the above command alone did the trick. I also had to remove the broken binaries installed by the script from /usr/local/{bin.share/gcm}

Thanks for the suggestion - I've updated the docs with a link to .NET's install instructions. Note that, due to installation instructions differing based on the distro and version users are running, the best we are able to do is link to the page that provides further links for users to follow to use their respective package managers to install.

Alternatively, depending on your use case, you might try git-credential-oauth which is included in Ubuntu 23.04 and later https://repology.org/project/git-credential-oauth

sudo apt install git-credential-oauth

Unfortunately I have to keep using Ubuntu 22 for a while longer.

Unfortunately, we do not yet officially ship for Linux arm64, although that work is slated to coincide with Git's 2.42 release in September and is being tracked with this issue.

Good to hear official support is in progress.
