Error after installing flex and bison

I have installed flex and bison in ubuntu 9.10.I downloaded the the respective tar files and followed the instructions as it was given in the Install file. However after installation I got lex command not found when I tried using it. Moreover I found no lex file in /usr/bin.

Why didn't you used your package manager to install the 2 packages

Code:

apt-get install bison flex

Or, you can probably simply add soft links from flex & bison to lex & yacc, respectivley:

Code:

cd /usr/bin
ln -s /usr/bin/flex lex
ln -s /usr/bin/bison yacc

You may have to e root to do this, and you may have to change the flex & bison filespec to match where they really got installed.

Instead of lex command flex is working and instead of yacc bison is working. Anyway thank you
