## Overview



Hello. ���� With the recent [Alpine Linux 3.17.2](https://www.alpinelinux.org/posts/Alpine-3.17.2-released.html) patch release -- which includes OpenSSL security patches -- I'm no longer able to build an Alpine Linux Docker image with YJIT enabled for Ruby. Prior to the 3.17.2 patch release, I could build Ruby + YJIT without issue. Here's the error I'm seeing when building locally:



``` 

#0 409.6 gcc (Alpine 12.2.1_git20220924-r4) 12.2.1 20220924

#0 421.7    24 | # error YJIT unsupported platform

#0 421.7       |   ^~~~~

```



...but what I see in the `yjit.h` source code is:



``` 

// We generate x86 assembly

#if defined(_WIN32) ? defined(_M_AMD64) : defined(__x86_64__)

// x86_64 platforms without mingw/msys or x64-mswin

#else

# error YJIT unsupported platform

#endif

```



...so AMD 64 should still be supported.



## Steps to Recreate



Probably the simplest way to recreate this, locally, is to use my Docker project:



1. Run: `git clone https://github.com/bkuhlmann/docker-alpine-ruby`

1. Run: `cd docker-alpine-ruby`

1. Edit the top of the `Dockerfile` so it says: `FROM bkuhlmann/alpine-base:2.0.3` (this ensures Alpine Linux 3.17.2 is being used).

1. Run `docker build --platform linux/amd64 .`

1. Wait for the build to fail.
