And "make CFLAGS+=-O2 CXXFLAGS+=-O2" are optimization levels, managed by compiler.

Tu dois envoyer les documents HTML en utilisant HTTP. Alors, tu dois avoir un serveur Internet. Pour cette projet, Apache est trop grand. Node.js est simple et a des bindings InfluxDB. Tu pourrais avoir le serveur fait en Python (Flask, mentionnée par moi) mais creation dure. Node.js est plus rapide...

What do you use as your Web Server?

Enedil, que veux-tu dire pas douille ? Ce n'est je pense pas la bonne traduction, mais si tu nous donnes le mot en anglais, je pense que nous comprendrons. Le nom anglais, c'est "socket". C'est un solution plus rapide que MySQL. Et si une DB sera utilisée, les bases NoSQL ont de vitesse. ...

Mais tu dois avoir un serveur HTTP pour envoyer les données en forme d'une page Internet. Il y a nombreuses choses. Tu peux utiliser Node.js. Et comment partager les données entre le logiciel Python qui les génère et le serveur HTTP? Je peux penser de Unix Douille. Les docs de Socket pour Node.js so...

You must serve audio file from a web server to set the right mime to allow playing with HTML5 <audio> tag.

1. As far as I know you can run it on Raspberry Pi. 2. The best choice this days is Raspberry Pi 2. It has 4 core CPU and 1 GiB of ram - it makes this version significantly faster and thus speeds up deployment. 3. Raspberry Pi runs a full Linux flavour. In every language you can program on desktop L...

Does the issue still exist if you compile your app using LLVM/clang (avaliable in repositories)?

enedil

Can you clarify? Because it is hard to understand what are you asking for.

Basically, just get last version via gem and all should work.

Drag Idle icon from Menu to desktop.

Je dois vous excuser - je suis polonais. J'apprends le français depuis trois ans, alors ma niveau de langage n'est pas trop haute.

Tu peux utiliser Python avec le Flask module:
http://flask.pocoo.org . Il fait le développement rapide possible. Et, pour renvoyer les nouveaux donnés, utilise Ajax.

Bad. Should be

Code: Select all

/home/pi/skripta/skripta1 &
mono /home/pi/Desktop/Program/WattsonIngestionTool.exe

enedil

In /etc/rc.local you need to specify full path to .exe file.

enedil

Are you sure you are trying to run a .exe file, not a .cs one?

enedil

Have something like

Code: Select all

import os
# some code
os.system('cp ../current.jpg /home/pi/html/directory/currentstate.jpg')

# at the end:
os.system('rm /home/pi/html/directory/currentstate.jpg')

in your Python script.

GCC is a critical component. No one can tell that v4.8 is enough stable and bug-free to enter stable stage. Nobody wants to guarantee the non-tested software. That's why GCC 4.8 is not included. And installing GCC 4.8 is quite easy, so no need of.

Edit file ~/.config/gtk-3.0/settings.ini.
Insert

Code: Select all

[Settings] 
gtk-icon-theme-name=Tango

Save file, restart X server, see if worked.

Try

Code: Select all

mono /path/to/application.exe

Sudo ran from /etc/rc.local is not required since every process there runs with root privileges.

I think that is the idea of Mono. You can develop on Windows and deploy to Pi, or even develop on Pi and deploy to Windows. I assume Mono maps Windows Forms to whatever native API is appropriate to the target. It appears that may be GTK+ on Raspbian. It surely isn't. It is plain X11. Mono’s Windows...

To get number of computing cores, run

Code: Select all

Since OpenElec is a GNU/Linux Distribution, it should run VLC. VLC is free software and it was running on Linux since the very beginning.

You should note that using GNOME 3 on Raspberry Pi will be a pain. 2 GiB of ram is the absolute minimum.

If the only pourpose of running HTTP server is serving two text files, do not use heavy Apache. Try built-in Python 3 module: import http.server import socketserver PORT = 8000 # If you want port 80 (default), you need to run script as root (using sudo) Handler = http.server.SimpleHTTPRequestHandler...

And why it's done that way? Answer is simple: Debian version used to create Raspbian is Wheezy, which is currently stable. Which means that there won't be non-security updates. So the GCC version released is 4.6. However, newer compilers provide better binary files (faster, smaller). That's the reas...
