How to install GNU flex or lex on Raspbian Raspberry

I need to install EyedDB for studies and I'd like to run it on my Raspbian Raspberry. I downloaded and unzipped at /usr/programs/EyeDB where I ran first with Pi user as requested and later as root:

./configure

Then a bunch of lines is coming out and ended with

 error: you must have Gnu flex or lex installed to compile EyeDB

Any clues?

Well, just get it like you would get anything else:

# apt-get install flex

You'll also need

# apt-get install bison
# apt-get install libreadline6-dev # for a non-maddening command line

...after which configure --disable-doc and make will sing their merry little songs and be happy (The --disable-doc is needed as javadoc chokes on Database.java)

flex and bison are the GNU versions of the venerable Unix tools lex (scanner generator) and yacc (parser generator), used in countless compilers and interpreters. They are never needed at runtime, so there is no need for separate {bison,flex} and {bison,flex}-dev packages.
