CVS Emacs compilation problem

CVS Emacs compilation problem

[Martin Stemplinger]

Hi all,

I just checked out the emacs source from CVS. The compilation fails 
while preparing loaddefs.el with the message

Loading vc-cvs (source)...
Symbol's function definition is void: vc-find-root
make: *** [autoloads] Fehler 255

I'd appreciate any hints what mistake I made here.

TIA
Martin

Did you bootstrap it?  I don't recall the details, but try something along
the lines of `make bootstrap'.

It happens during make bootstrap. Should have mentioned it. Sorry!

The first thing to do is to read the INSTALL.CVS file.
It doesn't answeryour question IIRC, but it does tell you where to post your
question (emacs-pretest-bug@gnu.org).

The answer: remove the *.elc files with `make maintainer-clean' and the do
`make bootstrap'.

OK I will do that the next time.

That was it. Thanks!

line drawing characters

[Greg Hill]

I am using emacs (GNU Emacs 21.2.2 (sparc-sun-solaris2.7, X toolkit)) 
on a unix system under X.

I would like to create some simple line drawings by mixing 
line-drawing characters along with ordinary text.  Surely the One 
True Editor is capable of that, but I haven't been able to glean any 
useful information on how to proceed from the Gnu Emacs Manual 
(Fifteenth Edition), the Gnu Emacs Lisp Reference Manual, or anything 
I could find doing a Goolge search.

Can anyone offer me any tips?

Thanks.

Thanks, but that is not what I had in mind.  I am talking about using 
special line-drawing characters that are designed for that purpose, 
and are not part of the normal ASCII set.

Not as good as Emacs 21.3 or 21.3.50 (CVS), but should be recent enuf.

1. These line drawing characters must belong to some character set
    e.g. Unicode http://www.unicode.org/charts/PDF/U2500.pdf

2. Once you've identified the character set you want to use, you need to
    figure out which Emacs coding system supports it.  Then you specify
    that coding system with `C-x RET c' when you edit your buffer/file.

3. Finally, you'll need how to input those characters while you're
    editing.  If your keyboard can enter them directly, `C-x RET k'
    should handle it; but you may need to install LEIM and rebuild Emacs
    and use `C-\'.

Thanks.  So far what I have is...

1.  It appears as if U2500-2575 contains the glyphs I am after.

2.  I switched to a computer that has emacs 21.3.1with leim support.

3.  The variable 'charset-list tells me that there is a character set 
named "mule-unicode-2500-33FF", which sounds like it's probably a 
pretty good bet.

4.  The function 'find-coding-system-for-charsets tells me there is a 
coding system named "emacs-mule" that can encode characters in both 
mule-unicode-2500-33FF and ascii.

5.  I can use `C-x RET c' to create a new file in a buffer using the 
emacs-mule coding system.

Now, what I can't figure out is:

a.  How do I find out what character codes correspond to which glyphs?

b.  How to I get those glyphs to actually appear on my screen?  I 
tried eval-ing the following fragment of code

(let ((ic 0))
   (while (< ic 10000)
     (if (char-valid-p ic)
         (insert-char ic 1))
     (setq ic (1+ ic))))

with my "emacs-mule" buffer as my current buffer, and all I get is 
regular ascii, a lot of glyphs I am not interested in, and a lot of 
empty boxes which are probably where the glyphs I am interested in 
should be.

Any more tips you can give me will be greatly appreciated.

Thanks again.

`M-x list-charset-chars RET mule-unicode-2500-33ff' will show you a
table of the chars.  You can insert them with `M-x ucs-insert'.

If you see empty boxes, that means that you need to instruct Emacs to
use a font with coverage of the this Unicode range.

list-charset-chars for mule-unicode-2500-33ff gives me all empty 
boxes.  I am beginning to suspect that the problem is not so much 
with Emacs as it is with my X windows server (eXodus running on a MAC 
under OS-9), which must not have a matching font to use for painting 
the display.  I will be working with our IT department this week to 
(finally!) get my MAC upgraded to OS-10, in hopes that that will take 
care of the problem.

Incidentally, the following bit of code tells me that character codes 
in the range of 294912 (0x48000) to 311295 (0x4bfff) correspond to 
the mule-unicode-2500-33ff character set.

(let ((ic 0) first last)
   (while (< ic 500000)
     (if (eq (char-charset ic) 'mule-unicode-2500-33ff)
         (setq first ic ic 500000)      
       (setq ic (1+ ic))))
   (setq ic first)      
   (while (< ic 500000)
     (if (eq (char-charset ic) 'mule-unicode-2500-33ff)
         (setq last ic))
     (setq ic (1+ ic)))
   (cons first last))

But list-charset-chars for mule-unicode-2500-33ff shows characters 
(which are displayed as empty boxes) from 0x2020 to 0x7F7F.   Is 
there some function I haven't found yet that clarifies the 
correspondence?

Thanks again for all the help.

OK, if you're lucky it might work out-of-the-box.

Well, yeah but not quite.  2941912 isn't a valid normal char:

(valid-char-p 2941912)
=> nil

but it _is_ a valid generic char:

(valid-char-p 2941912 t)
=> t

... don't ask :-)

It's too bad neither of those commands is documented in the Emacs manual.

FWIW, `list-charset-chars' is documented in CVS Emacs.
