Bug #18666: No rule to make target 'yaml/yaml.h', needed by 'api.o'

https://bugs.ruby-lang.org/issues/18666#change-101366



* Author: duerst (Martin Dürst)

* Status: Feedback

* 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/...
