Not much documentation on this, and seems I’ve gotten pretty far in this; I would not be seeing the error, if the module was not at least getting called. 🙂

The crux of this biscuit is –docroot is not being set when executing using mod_fcgid within apache2.

When starting hello.wt from the CLI in terminal, it expects –docroot, as well as –http-listen parameters passed which then starts listening. The example starts an wthttp instance listening on 0.0.0.0:8080. This all works, and my C++ code is compiled, and executes correctly in the browser.

The issue is when trying to configure mod_fcgid with the above configuration. It’s still looking for –docroot parameter. How can I set this within the configuration? or how can I compile the examples to have this preset?
