Installing Processing on Ubuntu

I downloaded Processing for Linux and the one for Mac but both came up with error messages when I open the program icon processing

Hi @chrissatch,

Welcome to the forum! :wink:

Can you please format the error message with the </> button or use backticks around it like this: ```code``` → code

It seems that you posted the content of the bash script, is it what you wanted to do?

Yes, I am just learning programming I put in the <>

But I am taking a college level Processing course, and thought it would be easier to have Ubuntu but then I have been having trouble installing Processing the way it says from the instructions on the website. Is there a way to open it in terminal? Or is there any way that is easier because I don’t know what they mean by symlink and creating a new java folder in the bash script?

No problem! (just edit your message :wink: )

Yes I am myself running on Linux for everyday tasks and programming and you learn a lot by doing so!

The installation process should be straightforward, just run the .sh script from the command line:

$ cd processing-4.0.1 # Go into the processing folder
$ sh ./ # Run the install script

Then it will install Processing and add a menu shortcut in your applications.

You can also directly run it from the command line with:

$ ./processing


  • You can also run the install script without calling the sh shell program like so: ./
    This is possible because the file is executable:

    $ file POSIX shell script, ASCII text executable

    And it contains a Shebang at the top of the file telling the operating system which interpreter it should use:

    $ head -n 1

I did it in the terminal bu when I ran

< $ ./processing>

an error message ran saying:

./processing: 110: java: Exec format error

Hey josephh,

I got it running!! So happy, I was working on labs for my class in the web editor, but in the regular program I can do so much more with it!!!

Thank you very much, when I ran it through the terminal it loaded!

@chrissatch Hi, can you tell me how you solved this problem? I’m also trying to install and run Processing on a Raspberry Pi, and I’m getting the same error message (in Terminal) that you got back in October 2022:
./processing: 110: java: Exec format error

@chrissatch Never mind, I was able to solve it by switching from a 64-bit version of Processing to a 32-bit version of Processing.

Which is strange, because my Raspberry Pi 4 Model B says on the box that it’s got a 64-bit processor! But whatever, 32-bit works on this Pi.
