Hi All,

I would appreciate your answer very much on this. When I do ./configure in cygwin, I got the two following related messages:

checking for flex... flex
checking lex output file root... lex.yy

The above shows that I have flex. However, when I run make, I got this error

make[1]: lex: Command not found

I have installed flex in Cygwin. I did the following:

$ which flex
/usr/bin/flex

$ which lex
which: no lex in (/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:....)

I also echo $PATH and my $PATH leads to /usr/bin/flex.

I suppose that to use lex, one has to install flex, and I have done that, what's the problem?

Thanks for your help!

Regards,
KL
