After building CVS Emacs you have, src/emacs, src/emacs-22.0.50, and
src/emacs-22.0.50.1. Why three? What is the difference between them? On
my GNU/Linux system (Debian unstable) the first and last are hard links to
each other. Sample ls:
$ ls -li src/emacs{,-*}
24765 -rwxr-xr-x 2 happy happy 9378548 Jan 14 10:23 src/emacs*
21633 -rwxr-xr-x 1 happy happy 13622004 Jan 14 10:09 src/emacs-22.0.50*
24765 -rwxr-xr-x 2 happy happy 9378548 Jan 14 10:23 src/emacs-22.0.50.1*
One difference that I stumbled upon is that the emacs-22.0.50 binary breaks
documentation for functions defined in the C source. At some point I
accidentally symlinked ~/bin/emacs to src/emacs-22.0.50 in one of my build
trees. I always invoke emacs as ~/bin/emacs. Later I noticed that
describe-function always said "Missing arg list" when I requested
documentation for a function defined in C. Is that expected or is it a
bug?
To reproduce:
Run src/emacs -q and then C-h f make-network-process RET. You will get the
documentation for make-network process.
Then run src/emacs-22.0.50 -q and C-h f make-network-process RET. You
will get:
make-network-process is a built-in function in `C source code'.
[Missing arglist. Please make a bug report.]
Not documented.
