compiling an extension

Hello people, I know this list is not the right place to post this... But there'are people here that should know the answer. I wrote a simple php extension and I'm trying to compile it under windows (under linux is ok). To do that, I followed this tutorial http://deluxe-design.at/win-php-extensions/ adapting some parts to php5... I'm Using Visual C++ 2005 Express and the module compiles fine, but when I try to load through a php script using dl(), I got this error: Warning: dl(): studio: Unable to initialize module Module compiled with module API=20060613, debug=0, thread-safety=1 PHP compiled with module API=20060613, debug=0, thread-safety=0 These options need to match I compiled the project linking against php5.lib and not php5ts.lib, does anyone know how to compile a module turning thread-safety OFF ? bests Pablo
