Bug #21919: `libruby-static.a` links to wrong `Init_enc`
https://bugs.ruby-lang.org/issues/21919

* Author: reitermarkus (Markus Reiter)
* Status: Open
* ruby -v: ruby 4.0.1 (2026-01-13 revision e04267a14b) +PRISM [arm64-darwin20]
* Backport: 3.2: UNKNOWN, 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN
----------------------------------------
When building Ruby with `--with-static-linked-ext`, `libruby-static.a` links the `Init_enc` function from `dmyenc.c` instead of `enc/encinit.c.erb`, resulting in `uninitialized constant Encoding::UTF_8` error, among other things.

There seems to be a discrepancy between `INITOBJS` (https://github.com/ruby/ruby/blob/e730ac41be4d427f06540e0f67fa16bbdced4789/common.mk#L81) and `ENCOBJS`/`EXTOBJS` (https://github.com/ruby/ruby/blob/e730ac41be4d427f06540e0f67fa16bbdced4789/configure.ac#L3139-L3152).

Currently, the only workaround I found is to manually link `enc/libenc.a` and `enc/libtrans.a` to the final binary.

[ruby-core:124865] [Ruby Bug#21919] `libruby-static.a` links to wrong `Init_enc`

[nobu (Nobuyoshi Nakada) via ruby-core]

Issue #21919 has been updated by nobu (Nobuyoshi Nakada).

Status changed from Open to Rejected

`--with-static-linked-ext` means the extension libraries including encodings are linked to the ruby executable or library.so.
`-static.a` is not intended to link these extensions.

Which `library.so` is that exactly?

Can you please clarify *why* it is not intended?

I'd like to include a fully static Ruby interpreter in a Rust executable. Also needing to ship `encdb.so` and `transdb.so` kinda defeats the purpose of a having a static binary.

What would be the proper solution here?
