When running make on the newest master checkout, I get the following error:

transdb.h unchanged
generating makefiles ext/configure-ext.mk
ext/configure-ext.mk unchanged
make[1]: Entering directory '/home/duerst/ruby3'
make[2]: Entering directory '/home/duerst/ruby3/ext/-test-/thread_fd_close'
make[2]: *** No rule to make target 'thread_fd_close.c', needed by 'thread_fd_close.o'.  Stop.

This may (or may not) be related to https://github.com/ruby/ruby/commit/7564e066ff.

This is on an Ubuntu 20.04 on WSL2 on Windows 10.

Do ext/-test-/thread_fd directory and Makefile there exist?

Probably make -C ext/-test-/thread_fd_close distclean may help you.
Although configure-ext should remove no longer existing directory but may have a bug for deeper paths.

The directory exists, but the Makefile doesn't exist.

Probably make -C ext/-test-/thread_fd_close distclean may help you.

This says make: *** No rule to make target 'distclean'. Stop.. It doesn't help, unfortunately.

Although configure-ext should remove no longer existing directory but may have a bug for deeper paths.

Do you mean ext/-test-/thread_fd_close should no longer exist? Or something else?

Yes,renamed as ext/-test-/thread_fd.

You can remove the old directory, and ext/-test-/exts.mk file.

Many thanks for your help. I removed both the directory and the file. Now I'm getting the following:

transdb.h unchanged

ext/configure-ext.mk unchanged

make clean is sometimes needed when building CRuby (correct C files dependencies is still a mess to this day, not CRuby-specific).
Would that help here?

This file should be updated, but actually wasn't.
Could you try again after removing that file?

Thanks, that helped.
