Small bug in postgres' ./configure script and invalid bug-report-link on website

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
Thanks. Patch attached. This will be in 7.4. --------------------------------------------------------------------------- Arjen van der Meijden wrote: > 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.

Please backpatch into 7.3 branch too.
(How the heck did flex get to a .31 minor release?)

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. -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight, UK http://www.lfix.co.uk/oliver GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "Dearly beloved, avenge not yourselves, but rather give place unto wrath.

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I already downgraded back to 2.5.4a, I thought some compilation issues with postgres' devel version were caused by an out-of-date flex. But they were all due to an out-of-date bison (version 1.75 and later on 1.875 made it compile, while 1.35 failed).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 ;) Arjen > -----Oorspronkelijk bericht----- > Van: Oliver Elphick [mailto:olly@lfix.co.uk] > Verzonden: woensdag 7 mei 2003 7:41 > Aan: Bruce Momjian > CC: Tom Lane; Arjen van der Meijden; pgsql-general@postgresql.org > Onderwerp: Re: [GENERAL] Small bug in postgres' ./configure > script and invalid > > > On Wed, 2003-05-07 at 05:49, Bruce Momjian wrote: > > Tom Lane wrote: > > > Bruce Momjian <pgman@candle.pha.pa.us> writes: > > > > Thanks.

From your reply, I must ask: does 2.5.31 come after 2.5.30, or does it tweak 2.5.3? -- +---------------------------------------------------------------+ | Ron Johnson, Jr. mailto:ron.l.johnson@cox.net | | Jefferson, LA USA http://members.cox.net/ron.l.johnson | | | | The purpose of the military isn't to pay your college tuition | | or give you a little extra income; it's to "kill people and | | break things".

http://sourceforge.net/project/showfiles.php?group_id=72099 If they present it as the latest and the previous was .27, I suppose it really is .31 and not .3something :) Arjen > -----Oorspronkelijk bericht----- > Van: pgsql-general-owner@postgresql.org > [mailto:pgsql-general-owner@postgresql.org] Namens Ron Johnson > Verzonden: woensdag 7 mei 2003 13:46 > Aan: pgsql-general@postgresql.org > Onderwerp: Re: [GENERAL] Small bug in postgres' ./configure > script and invalid > > > On Wed, 2003-05-07 at 00:41, Oliver Elphick wrote: > > On Wed, 2003-05-07 at 05:49, Bruce Momjian wrote: > > > Tom Lane wrote: > > > > Bruce Momjian <pgman@candle.pha.pa.us> writes: > > > > > Thanks.

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 -- Oliver Elphick Oliver.Elphick@lfix.co.uk Isle of Wight, UK http://www.lfix.co.uk/oliver GPG: 1024D/3E1D0C1C: CA12 09E0 E8D5 8870 5839 932A 614D 4C34 3E1D 0C1C ======================================== "Dearly beloved, avenge not yourselves, but rather give place unto wrath.
