Emacs NOT running on runlevel 3 ?!

Emacs NOT running on runlevel 3 ?!

[Jaeil Choi]

It's a shame that Emacs cannot run on runlevel 3,
while vim works fine.
I only hope there's something I missed.

When it was executed with "-nw" command line option
on runlevel 3 of Fedora Core 3,
X11 dynamic library(!) camplains about undefined 'yKeycode'.
Do emacs really need X11 when it's executed with "-nw" option ?

If it's linked against Xlib: yes.  But it should be possible to
compile it w/o X (./configure --without-x) or try to link
statically or mount the partition with the X libraries.

I'm think about situations where we want to use Emacs in
emergencies to recover linux.
It's natural to be linked with Xlib, since we don't want to
use Emacs in text mode all the time.

Then, the question is, do we have to keep another version
of Emacs executable compiled without Xlib to use in runlevel 3,
while 'emacs -nw' works fine in terminals if Linux's on runlevel 5 ?

Probably that's not what it's meant to be.
Emacs is supposed to adapt itself to environment appropriately.

If emacs is linked against Xlib and the linker can't find it you
can't run emacs.  It's that easy.

Either you have two versions of emacs or you link it
statically.  BTW, if you want to use emacs to fix a broken
system, you don't want any dependencies on any libraries in
/usr/lib/.

I strongly recommend to compile your own version with as much
--disable-foo as possible and install it --with-prefix=/ (check
with ldd src/emacs if any dependencies are left and link
statically if you can't avoid them).

IMHO emacs is just not made for these kinds of editing tasks.
