Creating images using php4/gd

Hi, I'm having real problems getting gd working with php4. I am using WinNT 4.0, php 4.0.0 (php4apache.dll), Zend v0.98 and Apache 1.3.12 (win32), I downloaded the GD dll from http://download.swwwing.com/php4/modules/ but if I add it to the php.ini, when I start Apache I get an error "The procedure entry point zend_error could not be located in the dynamic link library php4ts.dll". I get the same error if I use the dl function in a php function. Using Microsoft's "Depends" to check the DLL's I see that the php4ts.dll I have does not have a zend_error function, but does have a zend_error_cp function. I have tried re-compiling php4, apache and gd to no avail. (using vc++ v6.0) I was unable to create a working gd.dll (my knowledge of such things is sketchy at best...) I have scoured the web and usenet and see that other people are having similar problems, but no "how-to" guides to creating or using gd with php4. Are you able to help? cheers, trev
