Unable to install libv8 within docker running on Apple M1

[hegwin]

Hi Team, I'm trying to install libv8 in a docker container running in my MacBook Pro with M1 chip.

I got following logs after executing gem install libv8 -v 3.16.14.19

Building native extensions. This could take a while...

The image I'm using is ruby:2.7.2.

And in my container:

$ ruby -e 'puts Gem::Platform.local'
aarch64-linux

I resolved a similar issue with the v8 gem by building the image using the platform option.
Example: docker build --platform linux/amd64 -t image-name .

I am also in need of running this in a docker image with arm and failing. It seems like newer versions of libv8 are easier to install but since rubyracer is pinned to 3.16 we need this version to work. I tried manually forcing arm in the architecture (you can see somehow it detects x64), but ran into other issues:

/usr/bin/make -j2 arm.release ARFLAGS.target=crs

	build/gyp/gyp --generator-output="out" build/all.gyp \

  ^

I dont see an arm64 option either. I have been banging my head trying to figure it out, any help would be appreciated.

[henrymazza]

Docker on ARM is basically a Raspberry Pi, follow here #261

[shaheen-edmodo]

@henrymazza all the threads I have seen specify newer versions of libv8, I am specifically talking about 3.16. I don't even think that version was fully implemented to support arm based on other threads I have read but I was curious if anyone figured anything out since then.

This saves my day. Thanks so much :)

Thanks for this tip.

This also resolved the issue for me, but I don't understand why?

[Linell]

If you're hitting this issue from docker-compose, there is a platform flag that resolved the issue for me.

[lloeki]

docker build --platform linux/amd64 -t image-name .

This also resolved the issue for me, but I don't understand why?

You are now using an amd64 a.k.a x86_64 image, either emulating the CPU under qemu or using Hypervisor.framework or Virtualization.framework, the latter which can use Rosetta 2 for Linux.

since rubyracer is pinned to 3.16 we need this version to work

We cannot stress enough that moving to mini_racer is the only viable option.

Closing.
