`pack build` segfaults on M2 mac + podman
Summary
pack build segfaults on M2 mac + podman
Reproduction
Steps
- follow pack + podman setup guide - https://buildpacks.io/docs/for-app-developers/how-to/special-cases/build-on-podman/
-
pack build sample-app -p samples/apps/ruby-bundler/ -B cnbs/sample-builder:jammy - 💥
Current behavior
...
[builder] [DEPRECATED] The `--path` flag is deprecated because it relies on being remembered across bundler invocations, which bundler will no longer do in future versions. Instead please use `bundle config set --local path '/layers/samples_ruby-bundler/bundler'`, and stop using this flag

Hi @mpern.
But it looks like it is a problem with our sample ruby buildpack on ARM
There are some documentation around some buildpacks and builders available for ARM arquitectura, like the one from Daniel or Dshaun you can give it a try also.
I don't think it's the buildpack.
After switching to colima to manage my docker runtime, it "just works"
> colima start --cpu 4 --memory 16
> export DOCKER_DEFAULT_PLATFORM=linux/amd64
> pack build sample-app -p sample/apps/ruby-bundler/ -B cnbs/sample-builder:jammy

I think, because you are setting your platform to be linux/amd64, we are working to support arm architecture, but today it is limited.
the thing is, you are trying to use the sample builder cnbs/sample-builder:jammy, this builder is based on jammy linux/amd64, also the ruby buildpack is probably pointing to linux/amd64 binaries, then when you try to run that on linux/arm you get into issues, because you need a builder/buildpacks that are compliant for arm architecture. This is a known issue, and we are working on that direction. (see this RFC).
That's why I suggested to try to use the builders from Daniel or DShaun because they already did the job to compile, some of them, for arm architecture.
If you run pack build and you uses a compliant arm builder and buildpacks, you should be able to get your app image built correctly
