Best method to create a c++ app to communicate with nginx

by

No one here seems to have addressed the actual question, though some nice work arounds have been offered. I’ve been able to build C++ modules for nginx with a couple of minor changes.

  1. Change the module source file name to end with .cpp so gcc realizes it is dealing with C++.
  2. Make sure all your Nginx includes (e.g. ngx_config.h, ngx_core.h, etc.) are wrapped with an extern "C" { } structure. Similarly make sure any functions called through Nginx function pointers are declared with a wrapper.
  3. Add --with-ld-opt="-lstdc++" to your “configure” invocation when setting up Nginx.

With those three steps your module should compile, build, link, and actually work.
