Yes. First time using it.

Required jar files for Windows 10:

Thanks for the reply  
I undestand the files have to be in the code directory, not in processing libraries ditectory.  
I have a newer version 7-4- 0 taken from the maven website.  
If you could share your sketch i would be obliged.  
It’s been quite a while since i last made a program and I’m not fluent with github  
Regards

That did not work for me with Processing 4.5.5 on W10.

These are the libraries in JAR files that I was successful with and shared in previous post:

- _oshi-core-shaded-6.1.0.jar_ bundles many of its dependencies
- _jna-5.19.1.jar_ required
- _jna-platform-5.19.1.jar_ required

Once you have those then you can start.

You have to start somewhere!

The GitHub repository I shared has a _SystemInfoTest.java_ example from which I extracted what I needed and adapted to work with Processing.

Minimal example:

There is a learning curve to all of this and I spent a couple of hours on research, getting this library to work and understanding some of the errors vs warnings.

Adding an _external Java library_ is a challenge on top of just learning Processing.  
You need to invest the time in Processing and Java initially.

Resources:

- [https://processing.org/](https://processing.org/)

- [Library Overview · processing/processing4 Wiki · GitHub](https://github.com/processing/processing4/wiki/Library-Overview#another-alternative-using-the-code-folder) states:

> When running the sketch, all packages found in the `.jar` file will automatically be added as import statements in the sketch (though invisible to the user).

This is what Processing generates “under the hood”:

_ **Update** _

I did some further exploration.

Keep in mind that the library has dependencies and these are listed in the Maven repository for the library.

I used the _oshi-core-6.6.3.jar_ (Java 17) to work with Processing 4.5.5 (Java 17).

 ![image](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/1/1/11b7cc9dca40a5d7b1e429eeb08d2f5f53a29231.png)

This update generated no warnings:

I am not an expert by any means on any of this but with experience and persistence I will work toward a solution or a compromise.

Cool library!

Lots to explore with it:

When I try to add ‘`import org.slf4j.Logger`’ I get this error message:

 ![errs](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/5/4/54e6f8da0769e17f7f81dc1c9495998969f15cdf.png)

Is there any graceful way to get around this? I am reluctant to alter all of these apps by deleting the competing slf4j.jar files in order to run this one.

**Addendum:**

The only way that I could get ‘oshi’ to run was to move all the slf4j.jar files to a separate folder in each of the last four apps listed in the error dialog. I had no way to remove the Serial (part of Processing) files, but it ran anyway without doing this. I used the three libraries described above:
