[Cppcms-users] (no subject)

[eric m. <mid...@gm...>]

Hello,

I am looking for a way to update parts of a webpage via events from the
server.

I downloaded the Ticker example from the blog but as I try to compile it
(os = Ubuntu) I'm getting the following errors:
g++  -std=c++0x -O2 -Wall -g ticker.cpp -o ticker -lcppcms -lbooster
ticker.cpp: In member function 'void
ticker::async_send(booster::shared_ptr<cppcms::http::context>)':
ticker.cpp:83:39: error: capture of non-variable 'ticker::counter_'
ticker.cpp:97:9: note: 'int ticker::counter_' declared here

I also downloaded the Sse Ticker example from contrib and that does compile
but when I run it and access the page from firefox (127.0.0.1:8080/ticker),
I get a 404 Not Found and a popup with the following information:

-------------------------------------------------------
ticker
which is: text/event-stream
from: http://127.0.0.1:8080

What should firefox do with this file?
- Open with Browse
- Save File
--------------------------------------------------------

It doesn't display the tickers on the webpage.

I have a camera that is shooting photographs and want a webpage to reflect
what the camera is doing. So every time it shoots a photograph the
webserver should send the filename and sequencenumber of that photograph to
the webpage and the user must be able to inform the camera to stop taking
pictures via pressing a button. So HTTP requests to control the camera and
asynchronous status-updates to be displayed on the webpage.

I hope someone can help me out by either getting one of the ticker examples
working or providing another working example.

Many thanks!

Eric
