how to type math symbols in gnu emacs 2.12.19

[a.efremov]

Hello,
I run gnu emacs 2.12.19 on my linux f9 box. Upgrade is not an option
at least for a while. How I can type math symbols? No problem to
install additional el file. I'm not after for overkill solution but
rather for easy typing. Math symbols aren't my primary language I work
with. But sometimes usual i,j,k,l,m,n dont fit well or already in use.
It will be nice and more clear just type math. symbol on the go.
thank you in advance.

No, such an ancient version from the swinging sixties cannot be  
compiled today! (At least not a "linux f9 box".)

Oh sorry, error in version, obvious. Emacs 22.2.1

Then C-u C-\ TeX RET will put you in "TeX input method" where you can
enter math symbols using TeX notation.  I.e. just type \alpha to get
an α.

In which mode?

Can you consider installing GNU Emacs 23.2? It could make things easier.

[self@galaxy7 emacs-23.2]$ rpm -ql glibc-headers-2.8-8.x86_64 | grep

/usr/include/alloca.h

It's not clear why alloca is not found. I'm not sure about emacs 23.2

I have emacs-22.2-5.fc9.x86_64 that's ok for me. I only look for  few
common math symbols

Copy/past in emacs doesnt work properly as well or it seems to have a
weird look. For some symbols it's just fine.

thank you,

The file config.log can give you more details.


When the buffer's encoding is set to UTF-8 you can simply type the  
maths characters on your keyboard. When you set read-quoted-char-radix  
to 16 you can insert them by typing C-q 2 2 6 b <something not  
hexadecimal> or C-q 1 d 7 4 a <something not hexadecimal> to insert  
the character from this position in Unicode (U+226B or U+1D74A). UTF-8  
support is improved in GNU Emacs 23.x.


When you copy something in a modern windowing system, then not only  
some text is copied (and this text can be copied in many different  
coding systems) but also text attributes (bold, not upright, at 24  
pt). And this combination is inserted by pasting it into some buffer –  
in a different text encoding. Some customisation can be done in the  
windowing system and some in GNU Emacs.

hello,

adding soft link definitely helps to build binary > ll /usr/lib64/

emacs runs. Unicode symbols are ok on display. instead of just \xxx as
it was with emacs-22.
But. Menu doesnt work at all, emacs always pop up File-menu. then very
unfriendly black menu bar ..

I have a feeling that emacs is broken and doesnt work as expected. in
my configuration. Dont know what I should look at to spot the problem.

many thanks you for help,

Look at output of './configure --help' and set appropriate options.  
Study config.log.

Set X resources:

	Emacs*Background:	AliceBlue
	Emacs*BorderColor:	aquamarine
	Emacs*BorderWidth:	2
	Emacs*Foreground:	Black
	Emacs*bitmapIcon:	on

	Emacs.pane.menubar.faceName:	Libris ADF Std-9:style=Bold
	Emacs.pane.menubar.margin:	2
	Emacs.pane.menubar.shadowThickness:	3

or set up a gtkrc file (depending on the X toolkit used).

Read GNU Emacs (and possibly GTK) documentation.

Many modern Linux distributions that use a package system have the
ability to ensure necessary dev libraries and other required tools for
building a package are installed and will install them if there not. 

For example, under Debian based systems, you have apt-get --build-dep
<package> which will install all the necessary build dependencies for a
package. This can be very useful when you want to build a later version
from sources as it takes away some of the pain of ensuring all necessary
packages are installed. 

So, when I wanted to build emacs 24 from sources, the first thing I did
was run 

apt-get --build-dep emacs23

which ensured all the necessary packages to build emacs 23 were
installed. Then all I had to do was manually add any new libraries used
by emacs 24 (in this case, there were none). 

I believe (from memory) rpm has a similar facility. Recommend you look
into it as it will help ensure your system has the necessary libs for
building emacs - may make life easier. 

If you still have problems, check the config.log file. It will tell you
what was not available and what you may still need to install.
