Changes Differences between this release and the previous one
COPYING flex's copyright
MISC/ a directory containing miscellaneous porting-related
notes (for Atari, MS-DOS, Turbo-C, and VMS)
Decide where you want to keep flex.skel (suggestion: /usr/local/lib), but don't move it there yet. Edit "Makefile" and change the definition of SKELETON_FILE to reflect the full pathname of flex.skel.
Read the "Porting considerations" note in the Makefile and make the necessary changes.
To make flex for the first time, use:
make first_flex
which uses the pre-generated copy of the flex scanner (the scanner itself is written using flex).
Assuming it builds successfully, you can test it using
make test
The "diff" should not show any differences.
If you're feeling adventurous, issue "make bigtest" and be prepared to wait a while.
Install flex using:
make install
