Subject: [ruby-core:108106] [Ruby master Bug#18666] No rule to make target 'yaml/yaml.h', needed by 'api.o'

Issue #18666 has been updated by duerst (Martin D��rst).


I hoped https://github.com/ruby/ruby/commit/8e2a2ba0f9 (Merge psych master; Added files: ext/psych/extlibs; Modified files: ext/psych/extconf.rb; by @hsbt) might help with this. It didn't. But after I tried `./configure --enable-load-relative --disable-install-doc`, I got the following in the output:

```
duerst@Kloentalersee:~/14ruby$ make up; make

```

I haven't seen this before (but it could be easy to miss, because the output passes by very quickly). I'm just pasting it here because it could help diagnose this bug.

Bug #18666: No rule to make target 'yaml/yaml.h', needed by 'api.o'
https://bugs.ruby-lang.org/issues/18666#change-97070

* Author: duerst (Martin D��rst)
* Status: Open
* Priority: Normal
* Assignee: hsbt (Hiroshi SHIBATA)
* ruby -v: ruby 3.1.0dev (2021-06-03T06:59:33Z master 7e14762159) [x86_64-linux]
* Backport: 2.6: UNKNOWN, 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
When updating my Ruby compilation with `make up; make`, I hit the following error:

```
make[2]: Entering directory '/home/duerst/14ruby/ext/psych'
make[2]: *** No rule to make target 'yaml/yaml.h', needed by 'api.o'.  Stop.
make[2]: Leaving directory '/home/duerst/14ruby/ext/psych'
make[1]: *** [exts.mk:262: ext/psych/all] Error 2
make[1]: Leaving directory '/home/duerst/14ruby'
make: *** [uncommon.mk:307: build-ext] Error 2
```

`./ruby -v` is `ruby 3.2.0dev (2022-03-22T19:51:05Z master 0140e6c41e) [x86_64-linux]`

All of this is on Ubuntu 20.04 on WSL2 on Windows 10.

My guess is that this bug is related to recent changes in psych/yaml/...
