Gentoo doesn't even have a libtool 1.4.x available, afaict... I've down-graded automake and autoconf okay, but then I can't even emerge wget to try and download libtool from source because emerge wget requires autoconf more recent...

Meanwhile, what made me think that I was screwing up buildconf is actually not related to any particular version of automake/autoconf/libtool at all, as I get the same thing with all combinations readily available under Gentoo, as well as using the documented versions, so I've opened a bug report: And, actually, as far as I can tell, having no libtool at all, for that matter.

I don't see how this could possibly have anything to do with libxml. zend_language_scanner.c is generated by flex from zend_language_scanner.l Your top-level Makefile should have a line that looks something like this: /Users/rasmus/php52/Zend/zend_language_scanner.c: /Users/rasmus/php52/Zend/zend_language_scanner.l @$(LEX) -Pzend -S/Users/rasmus/php52/Zend/flex.skl -o$@ -i /Users/rasmus/php52/Zend/zend_language_scanner.l And at the top of the Makefile you should see LEX=flex -Rasmus --- ## #31077 — David — 2007-07-19T06:59:23+00:00 URL: https://externals.io/message/31072#31077 · In reply to: #31075 > cvs co -r PHP_5_2 > > ./buildconf > > ./configure \ > --enable-fastcgi \ > --enable-debug \ > --with-pgsql \ > --disable-xml \ > --disable-libxml \ > --disable-simplexml \ > --disable-xmlreader \ > --disable-exmlwriter \ > --disable-dom \ > --without-pear > > make > > zend_language_scanner.c: No such file or directory I've had that exact same problem intermittently. Although there's a line in Makefile that tries to build this file (by using bison), it seems non-functional. Try "make Zend/ zend_language_scanner.c". In my experience, this line returns without error but performs nothing. If you manually execute the line in the Makefile (substituting the appropriate variables), you'll have a zend_language_scanner.c and things will be happy.

LEX=exit 0; I don't think that's right, eh? How'd that get in there? My flex is version 2.5.33 It's in /usr/bin/flex where it belongs, with all the other build thingies. I just emerege-d it like everything else, before I started. [and before I tried to down-grade autoconf/automake/libtool] If it helps, I did a `grep "LEX=" *` to try to see where it snuck in. acinclude.m4 and aclocal.m4 both have LEX="exit 0;" So whatever built those probably isn't behaving. config.cache has ac_cv_prog_LEX=${ac_cv_prog_LEX=flex} configure has a whole bunch of lines, and I suspect typing them here out of context won't help, so: http://l-i-e.com/flex/configure genfiles has: STD='... LEX="flex -L"... So how come it didn't find my flex? I can hack the Makefile and move on, I guess, eh? I'm starting to think I'm not being a complete bonehead.

So I dink around with the Makefile a bit changing LEX=flex and LEX= exit0; back and forth... I get past the zend_language_scanner bit, I guess, and then it blows up in my face with a whole bunch of errors about undefined reference in spl_autoload, basic_functions, tokenizer, php_execute_script, php_lint_script, zend_ini_parser, ... The undefined references are to things like: zend_destroy_file_handle zend_file_handle_dtor zif_highlight_file highlight_file zend_save_lexical_state open_file_for_scanning . . . Yeah, maybe I shoulda left the Makefile alone... :-) -- Some people have a "gift" link here. Know what I want?

The problem was that the version of flex I had was 2.5.33, which is the latest version. However, 2.5.4 (an older version, confusingly) is the only version supported by PHP (which is noted in the documentation). 2.5.33 is not supported because backward compatibility was broken. (http://bugs.php.net/bug.php?id=39895) However, configure sees this as a warning and not a fatal error. But since there's no copy of zend_language_scanner.c in CVS, this is in fact, fatal. To make it even more difficult for people to figure out what's wrong, it changes $(LEX) to "exit 0;" which of course makes the make of zend_language_scanner.c succeed silently. I suppose if it returned anything else, there would be problems if zend_language_scanner.l was accidentally touched. I think the moral of the story is probably to add zend_language_scanner.c to CVS.
