# PHP 5.2 - No easy installation for users anymore? - Thread: https://externals.io/message/24123 - Original archive: https://news-web.php.net/php.internals/24123 - Started by Stefan Esser on 2006-06-14T18:02:13+00:00 - Messages: 9 - Reply by email to internals@lists.php.net - More for agents: search with https://externals.io/search.md?q={query} · JSON API at https://externals.io/api · documentation at https://externals.io/llms.txt --- ## #24123 — Stefan Esser — 2006-06-14T18:02:13+00:00 URL: https://externals.io/message/24123#24123 Hello, I just wanted to ask if we really want to bail out in configure if the installed flex is not 2.5.4. This stops everyone with f.e. Debian Sarge to install PHP 5.2 (if he has installed flex on his system). The normal user will never need flex for PHP's configure but it could be that he needs flex for other software. With PHP 5.2 this has become an either or. Greetings Stefan --- ## #24124 — Nuno Lopes — 2006-06-14T18:14:54+00:00 URL: https://externals.io/message/24123#24124 · In reply to: #24123 Hi, Currently we have to bail out if a new flex is installed, because the new flex versions simply die when parsing the flex skeleton bundled in the Zend folder. Why this happens? because flex has suffered a lot of changes and doesn't support the old skeletons. So currently we are stuck with the old flex version. This problem is so irritating to me, that I even have that in my TODO list. The new flex already supports re-entrant parsers, so we could get rid of the bundled skeleton plus all the engine hacks related with flex.

IMHO the correct way would be to warn the user about the incompatible flex version (like we did before) and then internally make configure believe that NO flex is installed. This should work, shouldn't it? Otherwise we really have the problem that a normal user cannot install PHP 5.2 anymore.

Are you talking about CVS or snapshots here? regards, Derick --- ## #24127 — Stefan Esser — 2006-06-14T18:49:54+00:00 URL: https://externals.io/message/24123#24127 · In reply to: #24126 > > […] > > Are you talking about CVS or snapshots here? > There have been a change in configure.in by ilia 4-5 weeks ago, that changed the warning to a bailout. If you now compile a snapshot it will bailout in configure because you have the wrong flex (although you don't need it at all for a snapshot).

That is besides Stefan's point. The snapshot and release tarballs come with pre-generated scanners and parsers. Neither flex, nor re2c, nor bison should be needed. Yet the configure script bails out if it finds an incompatible version of one of these tools although the tool will not be used during the "make". -- Sebastian Bergmann http://www.sebastian-bergmann.de/ GnuPG Key: 0xB85B5D69 / 27A7 2B14 09E4 98CD 6277 0E5B 6867 C514 B85B 5D69 --- ## #24144 — Robert Amos — 2006-06-16T06:08:09+00:00 URL: https://externals.io/message/24123#24144 · In reply to: #24143 I agree with Sebastian and Stefan. If its not "necessary" in order to compile/use PHP for everyday users then it should throw a Warning and keep on going. Joe Average might not know that flex, re2c or bison was installed a dependancy for another service, etc. -bok > > Michael Gall wrote: > > […] > > That is besides Stefan's point.
