Sorry. Please ignore the it. It is because my manual configure failed. The configure command:

./configure —with-mac --with-modules --disable-acl --without-makeinfo CFLAGS="-O2 -g0"

The error message:
————————————————
config.status: creating src/config.h
config.status: executing src/epaths.h commands
make: *** No rule to make target `epaths-force’. Stop.
config.status: error: ‘src/epaths.h’ could not be made.

It seems that “—without-makeinfo” for configure doesn’t has effect while It works well for the origin
emacs-26.

Why do you need that option? If the manuals in the Info format are
part of the tarball, you will not need to run makeinfo anyway.


It is because the makeinfo command on macOS is too old to make.
