Hi List,

I'm using flex 2.5.31

acm@server pgsql $ flex --version
flex 2.5.31

And get this warning from the configure-script (in latest cvs):

checking for flex... no
configure: WARNING:
*** The Flex version 2.5.3 you have at /usr/bin/lex contains a bug. You
*** should get version 2.5.4 or later.
configure: WARNING:
*** Without Flex you will not be able to build PostgreSQL from CVS or
*** change any of the scanner definition files. You can obtain Flex
from
*** a GNU mirror site. (If you are using the official distribution of
*** PostgreSQL then you do not need to worry about this because the Flex
*** output is pre-generated.)

Of course the regexp on line 3580 of the configure-script is wrong:
if $pgac_candidate --version | grep '2\.5\.3' >/dev/null 2>&1; then

I don't know a real solution, probably something like changing the grep
to read:
grep -e `2\.5\.3$'
Or adding a second grep to grep out 2\.5\.3[0-9]

Ow and the reason why I didn't try reporting this via the "Report a bug"
link on the postgresql-website is because that gave me a 404-error.
"Not Found
The requested URL /bugs/bugs.php was not found on this server.

Apache/1.3.27 Server at www.ca.postgresql.org Port 80"

Regards,

Arjen

Please backpatch into 7.3 branch too.

But remember that flex 2.5.31 breaks the existing lexer code. In spite
of being only a minor release, its code requirements are not completely
compatible with 2.5.4a.

Yes I already downgraded back to 2.5.4a, I thought some compilation
issues with postgres' devel version were caused by an out-of-date flex.
But they were all due to an out-of-date bison (version 1.75 and later on
1.875 made it compile, while 1.35 failed).

Although it is still a bug in de configure-script ;)

From your reply, I must ask: does 2.5.31 come after 2.5.30, or does
it tweak 2.5.3?

If they present it as the latest and the previous was .27, I suppose it
really is .31 and not .3something :)

The former.

I don't know exactly what has been going on, but I think:

2.5.3 is an old buggy flex
2.5.4a has been the standard for a while
2.5.30 was recently released to the world as the next flex and
2.5.31 seems to be some fixes and enhancements on that
