Hi, My guess is that SQL team may be linking with VC9 required libraries statically and you are not. It works because you have VC9 runtime on your machine. Thanks, Don. -----Original Message----- From: Richard Quadling [mailto:rquadling@xxxxxxxxxxxxxx] Sent: Thursday, April 29, 2010 8:16 AM To: php-windows Subject: Compiling PHP with MS SQL Server Driver for PHP support Hi. Compiling using VC9 Express Edition. I'm ending up with a php_sqlsrv.dll of 88KB The VC9 x86 nts version supplied by MS (php_sqlsrv_53_nts_vc9.dll) is 227KB. If it had been just a few bytes, then OK, but to be over 40% smaller is a significant difference. Any ideas? As far as I can tell, it all works just fine too!
