Hello Björn,

Thank you very much for trying on your Pi.

So that seems to confirm that there is indeed some problem on this 
machine with Simple Components.

I'll try to figure out why but I can't say when. Time is a scarce 
resource unfortunately...

Cordialement,

Hello there,

Since "Gnoga" uses "Simple Components" and this one has tests available 
I have compiled and run "test_http_server" and got the log file attached 
which may shed some light on the problem I'm facing on the Raspberry Pi.


It looks like some parts of the request are lost somewhere since it says :
192.168.0.206:52790 > |GET / HTTP/1.1%0D%0AHost:

Anyone else running "Gnoga" or "Simple Components" on Raspberry Pi 1

I have tried assigning apache2 port 8080 on raspbian and it works also.
So I don't think it is related to port number or firewall.

Hello there,

I am using this Raspberry Pi 1 Model B+:

It runs Raspbian Jessie up to date and I have used git to
get a fresh
Gnoga to play with.

I have issued command "make release", and after some hours
got it compiled.
Then "sudo su", "make install" and after some more time
got it installed.

Trying to compile "Ada for Automation" works also but the
applications
fail to answer to http requests although they run fine for
what I can
tell. Of course, I have some other targets, PC based
Debian, where there
is not such problem.

One can even play with :
http://ada4automation.slo-ist.fr/

I have compiled the first tutorial fine and it runs BUT it
does not
respond as well to http requests.

It says the usual stuff about directories and waits on
port 8080.

The Firefox on my PC complains that the connection is
reinitialized.

Wireshark running on the PC sees the connection, the http
request and
the closing of the connection from Raspberry Pi side.

Of course, I can ping the Pi, the Modbus TCP connection
works as
expected, and Apache can serve pages on port 80.

So only Gnoga / Simple Components seem to have some kind
of problem. Any
idea ?

Thanks for your hard work and kind support.

had a higher priority than food and family but I've not given up 
on things and hopefully more involved soon :) I still have a number of 
plans for Gnoga's development and tools for it.

[Gnoga-list] Ada for Automation : A4A_Piano using Gnoga

2016-01-10 Thread LOS Stéphane

Hello there,

I have added to the "Ada for Automation" project a simple application 
using Gnoga for the web UI.

It is hand made SVG connected to a MVC like Ada code.

It has this face :
http://slo-ist.fr/wp-content/uploads/2016/01/A4A-App6-A4A-Piano-Local.png

The code is here :
https://gitlab.com/ada-for-automation/ada-for-automation

It can be compiled with the provided "a4a_piano.gpr" project file or the 
makefile.

It can be tested using the provided "a4a.gpr" console project or the 
"a4a_gui.gpr" GtkAda project.

Running either one will connect it via Modbus TCP to the "piano" and 
allow one to play with the command and pattern bytes.

Any comments welcome.

Gnoga is a great project !
Thank you very much Mister Botton and Mister Kazakov for your hard work.

Hi,

another option would be to use the SVG backend (or any other image
backend, though SVG will likely produce the best results) from plplot,
and send that to the client.
