I am using the normal OpenBSD 7.4 installation from ftp.jaist.ac.jp,

It would be possible to create an alternative script using "readelf -d".
Thanks for the suggestion.

Yes, I applied that patch locally and proceeded with my project.

Of the recently announced OpenBSD 7.3 patches 006 through 009,
008 cannot be found on CVSweb.
And even after cvs update, sys/kern/exec_elf.c remains unfixed.
But, I was able to find patch-008 on GitHub.

z required
629MB for i386 and 1GB for amd64.
For example, if I delete the files under /usr/share/relink, I can
get within 512MB, but this is not a desirable installation method, is
it?

So the implementation of W^X in i386 has an impact.
Thank you for showing me the cause, it became clear.
swap /mnt
# umount /mnt
# mount -t mfs -o -s=1352M swap /mnt
mount_mfs: mmap: Cannot allocate memory
What could be the cause? Is there any way to increase the MAXDSIZ to
nearly 3GB?

tive language is, so I
can't give you a detailed answer, but I expect you can still find a
suitable one from packages.
If your native language is French, you may find an OpenBSD
