Problem with dll under Windows

Dear Sirs, Madam, would you be so kind and help me with DLL´s under Windows? While browsing in the help part of www.php.net I found this questin and answer, which I do not understand: ============================= 4. How do I get these libraries to work? You will need to follow instructions provided with the library. Some of these libraries are detected automatically when you run the 'configure' script of PHP (such as the GD library), and others you will have to enable using '--with-EXTENSION' options to 'configure'. Run 'configure --help' for a listing of these. ============================= After I downloaded and unzipped the PHP 4 system I searched for executable file "configer" in my computer but I did no find anything like that. Could you help me, please - where can I find program for configuring dll libraries under Windows? How can I use it? Are there (somewhere in web) step-by-step instructions? Will this solve the problem with dll-errors while writing and testing scripts? I use Personal Web server in Windows 98 second edition. Thank you very much. Jan Ryska Czech republic janryska@volny.cz
