Custom build rule

Hello internals! I have almost completed a SAPI, that allows NodeJS scripters to enable PHP from within their HTTP servers. Originally, I wanted to write this extension just for my own use, but as I see the many „dirty“ hacks that people use to run PHP inside their http server, I decided to make this extension more available, once its done and working. However, the build process is a bit complicated, as it plays between worlds; the autoconf based PHP build system and the GYP driven node extension build system. So far, I am working on the first solution: Building the extension using PHP’s build mechanism. As I know the procedure for building nodejs addons by their commands, I’d just need to add a custom action/rule to the build, that builds a static library/bundle with .node as file extension isntead of the usual ..so/.dll. How do I do that? Its two C++ files (tinythread.cpp, v8php.cc) that need to be compiled. v8php.cc houses the entire SAPI code as well as the nodejs bindings. And as a side note: When the user has previously built PHP with ZTS and Embed-SAPI, so that libphp5 is built, can they just link a SAPI against that? I see that php-config lists the SAPIs, and I wondered if there is a generated file that lists/depends on all the SAPIs. Kind regards, Ingwie
