i download flex (a lex generator) from
http://www.monmouth.com/~wstreett/le.../lex-yacc.html
and decompress the flex.zip
when I run ./configure script, shell display the following error:
:bad interpreter : no such file or directory
When I do
ln -s /bin/bash /bin/sh
shell tell me the file is already exist.
I modify the first line of configure script to #!bin/bash, but the bad interpreter error occurs again. Help me.
the configure script is as follows:
#! /bin/sh
