Hello PHP hackers,

What version of flex is needed to compile PHP5 from CVS?  My version
bails out like this:

[Thu Apr 17 10:58:15] per@salem:/usr/local/src/php-cvs/php5> make
Zend/zend_language_scanner.c
flex -Pzend -S/usr/local/src/php-cvs/php5/Zend/flex.skl
-oZend/zend_language_scanner.c -i
/usr/local/src/php-cvs/php5/Zend/zend_language_scanner.l
flex: fatal internal error, bad line in skeleton file
make: *** [Zend/zend_language_scanner.c] Error 1

[Thu Apr 17 11:09:44] per@salem:/usr/local/src/php-cvs/php5> flex -V
flex 2.5.31

[Thu Apr 17 11:10:04] per@salem:/usr/local/src/php-cvs/php5> dpkg -l
flex
[...]
ii  flex                                              
2.5.31-3                                           A fast lexical
analyzer generator.

It doesn't warn me, and obviously, 2.5.31 > 2.5.4 so it should not... 
Still, this version does not seem good.

I should warn you, as 2.5.31 is borked. And I'm pretty sure the check is 
in (perhaps when you run ./buildconf though).

Yes, I agree.  But if it just checks whether the flex version is
>=2.5.4, it obviously "should not" fail on this flex version.

  The check is in but doesn't abort ./configure as it IMHO should.

  The only supported version of flex at the moment is 2.5.4 (or 2.5.4a).
  The only supported versions of bison are 1.28, 1.35 and 1.75.

Actually, it checks whether the version is == 2.5.4.  Maybe that was
what you were trying to communicate.

Anyway, I think a warning is not enough; it should bail out if the flex
version is wrong (since it will not compile otherwise).

Thank you, I will try again with these versions.

If you'd been paying attention you'll notice that this was suggested a 
few days ago already.
