in 2030 to download and run an Emacs-21 to see how it was back then :-)
FWIW, I was able to compile e21 on a current x86_64 machine running
Alma Linux 8 (I doubt the os matters much) with the attached.
Copied in m/amdx86-64.h from 22.3 as a starting point. I didn't try to
include X support, since I had no interest in it.
My configure invocation (largefile does not matter).
env CFLAGS='-g -w' ./configure --prefix=/usr/local/gnu/emacs-21.4
--without-pop --without-gif --without-gpm --without-x --with-x-toolkit=no
--without-xpm --without-jpeg --without-tiff --without-png
--without-toolkit-scroll-bars --without-xim --disable-largefile
I found it necessary to remove all the \-newlines from the Makefile.in's
since I could not find any cpp option to preserve them other than
-traditional, which then breaks the actual compilation in myriad ways
wrt system headers, etc.:
(cd src; mkdir ORIG; cp Makefile.in ORIG;
perl -p -e 's/\\\n//' ORIG/Makefile.in >Makefile.in)
# same for lib-src.
The normal make fails at the final dump; it gets a seg fault. But when
running temacs under gdb, with -batch -l loadup dump, it works. Did not
try to investigate, was just happy to have the binary.
Compilation with -O2 causes temacs to die immediately in malloc.
So just -g. Used the distro compiler:
gcc version 8.5.0 20210514 (Red Hat 8.5.0-10) (GCC)
Lots of memory failures along the way.
This set of configure outcomes is what seems to work:
Should Emacs use the GNU version of malloc? yes
Should Emacs use a relocating allocator for buffers? no
Should Emacs use mmap(2) for buffer allocation? yes
As a bonus for getting through it, the maximum buffer size is increased
to somewhere around 1GB (by experimentation).
Happy historical Emacsing,
Karl
