When compiling php in 64bit mode and statically linked to Apache then you'll receive an error that libphp.a is a 32bit library archive. Only the zend_execute.o ist 32bit, all others are correct.

In the Zend Makefile for zend_execute.c the CFLAGS are missing!

jason just made a post to the PHP-dev list about this, with a patch to allow this to work.  Can you try applying it and seeing if things work for you alright?

Sorry I don't have a link handy, but here's the general info:
Posted by Jason Greene, Sept 25, 2002.  Topic: [PHP-DEV] [PATCH] 64 bit PHP (long vs int problems)

[2002-09-30 06:26 UTC] nohn@php.net

Similar to http://bugs.php.net/bug.php?id=18640 ?

[2002-09-30 07:47 UTC] kalowsky@php.net

no this is a bit different I believe sebastian.

[2002-10-01 02:09 UTC] Manfred dot Metz at rsd dot rohde-schwarz dot com

The problem is a bit more complicated I think. I believe there is a problem in the Zend Makefile. The behaviour is different when using the Forte C compiler (Version 7) from SUN. Then every objectfile is compiled correct as 64bit obectfile. Only with gcc (Version 3.2) I'll result in this error.

By the way. My feeling is that there is some unclean 64bit code in the PHP source. I'm just evaluating the reason for a Bus Error during PHP scripting.

[2002-10-01 07:07 UTC] kalowsky@php.net

Yes Zend is optimized for 32bit systems, but we have gotten it running on 64bit systems.  

It still stands, have you tried the patch provided by Jason Greene?

In any case I'll make this as assigned to him since he has a patch started to take care of this.

[2002-10-01 07:39 UTC] Manfred dot Metz at rsd dot rohde-schwarz dot com

Yes I tried to apply the patch, but there is no chance to apply the Patch to php-4.2.3 because most of the code is rewritten in 4.2.3. Can you tell me to which php Version this patch belongs?

My testings about the Bus error point to some inconsistency in ext/standard/url_scanner_ex.c here is the dbx output:

(dbx) cont
t@1 (l@1) signal BUS (invalid address alignment) in url_adapt_ext_ex at line 804 in file "url_scanner_ex.c"

I believe it's for CVS head...

[2002-11-08 09:49 UTC] iliaa@php.net

I've compiled the latest CVS on a 64 bit Sun OS without any problems. I am guessing that the problem may have been fixed...
Could you please try the latest cvs and see if you still experience the problem?

[2002-11-08 12:04 UTC] sniper@php.net

Please try using this CVS snapshot:

  http://snaps.php.net/php4-latest.tar.gz
 
For Windows:
