Re: emacs26, ucs-normalize.el, Symbol’s function definition is void: regexp-opt-charset

[hx]

CFLAGS="-march=native -O2 -pipe -fomit-frame-pointer" \

./configure --prefix=/home/xyz/emacs26 --disable-largefile --without-pop --without-sound \

yesterday, I manually open emacs and make byte-compile on the ucs-normalize.el, then run make again, it worked.

today, I just do make clean && make distclean, delete all .elc files, sh autogen.sh, configure with above options,

make success without error.

I think I understand why, but just so I'm sure: can you tell how you
configured this build?  What was the command line with which you
invoked the 'configure' script?
