When I do a make CFLAGS=-O2 LDFLAGS=-s under flex I get the following message:
make CFLAGS=-O2 LDFLAGS=-s
cp ./initscan.c scan.c
touch .bootstrap
CONFIG_FILES= CONFIG_HEADERS=config.h:conf.in ./config.status
creating config.h
config.h is unchanged
echo timestamp >stamp-h

gcc -c -I. -I. -O2 nfa.c
yacc -d ./parse.y
Make: Cannot load yacc. Stop.

I have put the full path to flex in my profile.
Can anyone help Please?

You need to install yacc first.

Well, since you are using gcc you almost certainly didn't purchase any sort of development system. Yacc and lex are bundled with any of the C/C++ deveopment systems. You need to install the Gnu version of yacc which is called bison.

Hi,

Check your /opt/langtools/bin directory to see if you have yacc installed (comes with any C/C++ development toolkit) If so, modify your path.

Else you can get Berkeley yacc from this site.
