Re: Linking problem with extension written in C++

There are a few header files that you have to include with extern "C" so their names get mangled properly into C++. Try wrapping php.h, php_ini.h and info.h in extern "C" and see how that goes. I wrote up a little article on this sort of thing, so if you're interested, check out http://www.tutorbuddy.com/software/phpcpp/phpcpp/. J Grzegorz Godlewski wrote: > I have written an extension.
