Processing is very difficult to use under linux!

empedokles

Hello. Couldn't you provide processing under the Ubuntu Software Center as a one click installation? You provide no clear instruction about how to use the tgz file under linux. While I could install it under ~/documents/processing.1xxx and run it with the command sudo ./processing inside this directory I'd like to have a link for it.

This is just the Processing forum. You aren't talking directly to the developers of Processing.

You should just be able to unpack the tgz file and use it as a directory. There is no "installation" involved.

empedokles

Yeah, but I can only use it via the terminal: sudo ./processing Inside the directory. By doubleclick it will show me the file in my text-editor.

i don't use ubuntu but this might help:

http://askubuntu.com/questions/76342/how-can-i-add-a-bash-script-to-the-unity-launcher

(this is more accurately a ubuntu problem, not a linux problem)

also, you shouldn't need to sudo the processing script, it's a really bad idea, security-wise.

empedokles

./processing works thanks.

But the link doesn't help me either. Where is the suggested place for processing under Ubuntu? Currently it sits under ~/Documents/processing

And how do I create an Icon for Unity sidebar (not the desktop)?

koogs

mine's under /opt but then i'm old-school. /usr/local is probably more correct

(i use /opt as /usr/local is, by default, under the root partition and i share my processing installation with a bunch of different distros / don't want to lose it during a reinstall.)

the unity sidebar was the reason i ditched ubuntu so i can't help you there.

empedokles

I don't have sufficient rights to unpack anything there. How to?

in a terminal window

sudo su -

should give you root permissions. ctrl-d to exit

Hint: symbolic links or "symlinks"

Empedokles,

In Ubuntu, right click on the Processing file, select properties, select permissions tab, and check "allow executing file as program"

Now when you double click Processing should run instead of a script opening in the text editor.

My "Processing.desktop" file content:

sudo su - should give you root permissions. ctrl-d to exit

Unfortunately I can't still unpack it to /opt via this file unpacker.

Unfortunately still not. But the standard-app is sublime text here. What would the standard-application for processing be?

How and where did you create this file and where is processing lying?

i have a feeling you're sudoing in a terminal and then using a gui tool to unzip the package. which won't work - the sudo will only apply to commands typed in that same window. typed.

but no matter - you already know that you can unzip and run processing from anywhere. so put it where you want it (/home/empdokles/processing?) and then use that address in your .desktop file

empedokles

Exactly. How do I make a sudo-like-command inside the GUI unpacker-window? I placed it in my home folder now.

koogs

this has some instructions

https://www.processing.org/tutorials/gettingstarted/

follow them and you'll end up with the system set up how you have it right now 8)

so concentrate on the .desktop file (i can't help you there, unfortunately - no unity)

I've made in some regular text editor. The Exec= & Icon= paths refer to my particular installation.
Which is merely where I've decompressed the downloaded file! ~O)

Another thing I've done was removing the "/java" subfolder to force it to use the system's JDK! :ar!
