Installing ARM version for Mac

[dmitryrn]

go1.16.7.darwin-arm64 is available here https://golang.org/dl/

But how do I install 1.16.7 darwin arm64 via gvm?

When I do gvm install 1.16.7, it installs darwin/amd64.

In case it helps, I've managed to get it working as follows:

• Download the ARM64 build
• Unpack into ~/.gvm/gos/
• Create a file in ~/.gvm/environments/ - just copy the file for a different version and change the version numbers in it
• Create an empty directory ~/.gvm/pkgsets/

Having done that, I can now do gvm use <version> and it seems to work fine.

Here's a "less pure" way of using gvm to install/manage go, but less involved: brew install go && gvm install go1.17.6 && gvm use go1.17.6 --default && brew uninstall go

Ok, so I got this working for me in the end 2021 MacBook Pro, running MacOS Monterey, M1 Chip. Trying to get gvm to install go1.15.6.

I downloading the binary manually from here:

https://go.dev/dl

I download the darwin-amd64 binary. 👈🧐 More on this in a bit.

First thing to do, is extract the tarball and just run the binary manually, check that it works on your machine.

Now follow sazzers instructions to manually add it to your .gvm folder.

Which binary to use?

So this is where I'm a bit confused. My understanding is that the m1 chip is an ARM64 instruction set, so I'd assumed that was the right on to use. But seems like the AMD64 instruction set is the one to use, is that because rosetta is converting it?

Does anyone want to enlighten me on this?

There's another way:

1. Download the ARM64 build, then install, make the version as default
2. gvm install go1.1x.x (any version you like), it would build from source
3. You get a ARM64 build from gvm install

After this, every time you want to install other version from gvm, then it would be built in ARM64

it works! Just replace the verion in the environments.

@sazzer Create a file in ~/.gvm/environments/ - just copy the file for a different version and change the version numbers in it

Can you elaborate on this, what's the filename and content?

[soulteary]

Maybe this will help you: https://github.com/moovweb/gvm/issues/406 You can install binaries directly without local compilation, which is a waste of time.

thanks @soulteary, this works great for me!

This worked fine for me and it's pretty straight forward solution, it only works to install go1.16+ with gvm though (AFAIK there is no support for arm64 for go older versions).

Homebrew installs at this time the latest amd64 version available, so I downloaded the arm64 installer from go official site instead. I executed export GOROOT_BOOTSTRAP=$GOROOT before install any version with gvm, but I do not know if it's required.

This can be put into a script called gvm-install-mac-version and be used like:

chmod +x gvm-install-mac-version
 ./gvm-install-mac-version 1.22.2
gvm list
gvm use go1.22.2
