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
|
||
|
|
|
||
|
|
