Usage

At first, you must patch nginx/auto/make to enable g++ compiler and C++11.

Please see directory "patch/auto".

For example:

patch -b make make.patch

Then configure nginx with:

./configure --add-module=path/to/ngxpp	\	            # ngx cpp module
			--add-module=xxxx			                # other modules
make

ngx_cpp_module is a pure header library, you should use ngx_cpp_module like this:

#include "NgxAll.hpp"	// include all C++ tools for http modules

Or

#include "NgxStreamAll.hpp"	// include all C++ tools for stream modules

Examples

Please see directory http, including echo/filter/variables and so on.
