Description:
------------
When I build PHP and the build directory (from where I call configure) is different to the source directory, I always (configure with or without params) produces the error that zend_language_parser.c was not found. When building from inside the source directory (./configure) is all nice and dandy!

Reproduce code:
---------------
cd build
../src/php-5.1.6/configure
make

Expected result:
----------------
"Build successfully done."

Actual result:
--------------
-I/home/fa/dev/build-area/php5/build/php/  -D_REENTRANT  -I/usr/include -g -O2 -pthread -DZTS   -c Zend/zend_language_parser.c -o Zend/zend_language_parser.lo
gcc: Zend/zend_language_parser.c: No such file or directory
gcc: no input files
make: *** [Zend/zend_language_parser.lo] Error 1

Please try using this CVS snapshot:

  http://snaps.php.net/php5.2-latest.tar.gz
 
For Windows:

@Johannes: the exact same error with 5.2 snapshot. Btw, the problem does not occur in Slackware 10.2.

Make sure you have yacc/bison installed.
 [2006-09-09 20:31 UTC] butterblume83 at gmx dot de 
@tony2001: does not help.

Is the configure-line:

  checking for flex version... invalid

interesting?
 [2006-09-09 21:13 UTC] tony2001@php.net 
Can't reproduce.
 [2006-09-09 21:27 UTC] butterblume83 at gmx dot de 
It works after I downgraded flex (2.5.31-38) to flex-old (2.5.4a-7). Please edit php's configure script so that a fatal error is thrown if the flex version is invalid.
 [2006-09-09 21:38 UTC] tony2001@php.net 
Stefan, your change broke the check for flex:
http://cvs.php.net/viewvc.cgi/php-src/acinclude.m4?r1=1.332.2.14.2.1&r2=1.332.2.14.2.2

The flex check works. The behaviour introduced with PHP 5.2 was unwanted. The original reporter reported the issue with PHP 5.1.6 which is proof enough, that my change that is only in 5.2 is NOT responsible.

Hi have tested 5.2 snapshot:

The bad logic introduced in some point. (Stefan had nothing to do with it)

As flex is required to build PHP from sources, then configure must bailout if wrong version/none is available.
 [2007-05-24 19:56 UTC] sniper@php.net 
Recheck: This was Stefan's fault in PHP 5.2.x. We bundle flex generated scanner files with source distribution. You don't need any flex installed for building PHP. (I remembered it was required, my bad)

And about the "build dir != src dir" builds: I do that always, no problems whatsoever. (using PHP 5.2 from CVS that is)

If you can't build php outside source directory, submit a new bug report. (when using snapshot / 5.2.3)
 [2007-05-24 21:42 UTC] sniper@php.net 
I'm feeling a bit stupid: There was more to fix but now everything is okay, even when you don't have flex/bison installed at all.
