2.
i saw a word "optimized"
and found this .configure cmd in folder e29/etc/ :
./configure --enable-checking='yes,glyphs' --enable-check-lisp-object-type
\
CFLAGS='-O0 -g3'
then rebuild again
$ make clean
$ ./auto
$ ./configure --enable-checking='yes,glyphs'
--enable-check-lisp-object-type \
CFLAGS='-O0 -g3'
$ make - j 4
run gdb,
because there is no gui emacs occur,
i have no way to input:
$ gdb ./emacs -q
