installing bison and flex
 

How 2 install flex and bison which is important for making work yacc and lex. If any one know give the step by step installation procedure. Thank you

That depends which distribution of Linux you're using

Hi.
My aim is to install and hopefully learn to use tetex, but when I tried to ./configure it said I needed lex or flex. I arbitrarily choose flex, download it, and try to install it. When I try to make it I get a message to say that there's no such command as yacc. Not knowing what that is, I google and find something called bison which is supposed to do the same thing. That gets installed and made no problem, but flex still gives me the yacc error, so I have no idea where to go from here. I'm using Suse 9.2.

There is a tetex package that comes with SuSE.

Try this command for more information:
rpm -q tetex te_latex

After installing tetex and te_latex, there will be documention under /usr/share/texmf/doc.

thanks. will take a look in a mo. .c.

Any kind of help will be truly appreciated.

No reason to download any system software in Linux. Never.
It's all available in the Package Manager = 'synaptic'.

Or use the command line in a terminal window :

sudo apt-get update
sudo apt-get install flex g++ automake autoconf make

..

better: apt-get install build-essential

http://packages.ubuntu.com/karmic/build-essential

""If you do not plan to build Debian packages,
you don't need this package. ""


And flex is not included.!
