PS:
As suggested, i try to build dub from github, following: https://github.com/dlang/dub/releases

I call ./build.d - and everything stops, and machine crashes.

Same for the master branch

Hey Seany,

DaNode author here, the mean function is only used to compute some server statistics. I am sorry to hear it didn't compile out of the box with the latest DMD compiler, I only tested up-to 2.088.0

I just installed the latest version 2.090.0 but also using this version it compiles fine. Looking into the dlang docs it seems it was moved from std.algorithm to std.algorithm.iteration, I wonder why it doesn't find this function.

However I just added a mean function to the web server since it should always find this function.

Could you pull the latest master branch and try compiling it again ?

dub -- -p=8080

then see if the web server works by navigating to

http://localhost:8080/

let me know if you run into any other issues

Kind regards,
Danny

Hey Seany,

A quick follow up post. I think/suspect that something might be broken in your dub installation if the mean import is not found. This is the first import from the phobos standard library in the project.

Could you try compiling the DaNode web server without using dub ?

git clone https://github.com/DannyArends/DaNode.git
cd DaNode
rdmd danode/server.d -p=8080

This should work, when you have a working D+Phobos standard library installation. If this throws error of being unable to find the canFind import (now the first one) then somehing in your dub/dmd installation is broken and you will probably have to reinstall dmd+dub

Kind regards,
Danny

I solved this by following:

sudo wget https://netcologne.dl.sourceforge.net/project/d-apt/files/d-apt.list -O /etc/apt/sources.list.d/d-apt.list
sudo apt-get update --allow-insecure-repositories
sudo apt-get -y --allow-unauthenticated install --reinstall d-apt-keyring
sudo apt-get update && sudo apt-get install dmd-compiler dub


then dub showed the error : out of memory.

I applied: dub --build-mode=singleFile

That seems to work

I will test this tomorrow.

## 1. For simple server you can using hunt-http library.

Sample code:
```
import hunt.http;

void main()
{
    HttpServer server = HttpServer.builder()
        .setListener(8080, "0.0.0.0")
        .onPost("/", (RoutingContext context) {
            context.end("Hello World!");
        })
        .onGet("/user/:name", (RoutingContext ctx) {
            string name = ctx.getRouterParameter("name");

            ctx.write("Hello " ~ name);
            ctx.end();
        })
        .build();

    server.start();
}
```

## 2. For full server, you can using hunt-skeleton (hunt-framework based):
```bash
git clone https://github.com/huntlabs/hunt-skeleton.git myproject/
cd myproject/
dub run -v
```

You can Add pages in `config/routes` , like this:
```
GET   /   index.index
GET   /user/{name}    user.detail
```

Add Controller file `controller/UserController.d` :
```
module app.controller.UserController;

import hunt.framework;

class UserController : Controller
{
    mixin MakeController;

    @Action
    string detail(string name)
    {
        return "Hello " ~ name;
    }
}
```

Build and run it:
```
cd myproject/
dub run -v
```

You can see it in the borwser:
```
http://localhost:8080
```

How much memory does this machine have? Is it a virtual machine provided by a hosting company? My suspicion is that your server is very slow for some peculiar reason.
