Ok, just recompiled emacs with dumping support, and running
$ emacs -Q --batch --eval \
'(dump-emacs "./demacs" "/usr/bin/emacs")'
on the NanoNote gave me:
[..]
Loading ediff-hook...
Finding pointers to doc strings...
Finding pointers to doc strings...done
emacs: Can't allocate buffer for /usr/bin/emacs
So it wants to pull a full copy of the emacs binary into memory?
This problem I can workaround by changing the Linux overcommit setting,
but then dumping fails with another problem:
$ echo "1" > /proc/sys/vm/overcommit_memory
$ emacs -Q --batch --eval \
'(dump-emacs "./demacs" "/usr/bin/emacs")'
[..]
Finding pointers to doc strings...
Finding pointers to doc strings...done
emacs: Program segment above .bss in /usr/bin/emacs
So what's that supposed to mean?
cheers,
David
