I think I've just replied to you via email too - I'm really sorry to hear you're having these issues, but it seems you have simply downloaded the wrong file.

Like many other open source projects, all my libraries come as binary & source distributions. The separation has mainly to do with trying to keep file sizes down, but each release format has also a somewhat different intent:

The binary release is intended for library users and in my case is exported in a format to be readily deployable in the Processing libraries folder. This is the release version for 99% of all users...

The source release version is intended for library developers or people who simply want to hack the source code and this archive does not contain a working library JAR file.

I'm sorry if this is confusing for novices, but this is 100% standard practice in the open source world and I'm not intending to divert from this. If you want to just use a library, you usually get the binary distribution, else you grab the source and build a binary yourself...

I've just edited the version comments on the download page to make this more obvious:

http://code.google.com/p/toxiclibs/downloads/list

To just get the libraries in a Processing ready format, download the binary releases. E.g. the current core library is here:

http://toxiclibs.googlecode.com/files/toxiclibscore-0014.zip (note the lack of "src" in the file name)

When you unzip this file you should end up with a folder structure like this:

+-toxiclibscore
+--docs
+--examples
+--library

Now simply drag & drop the entire "toxiclibscore" folder inside the "libraries" folder of your main Processing sketchbook folder (on OSX the default location is here Documents/Processing/libraries)

Once this is done, restart Processing and then you should be ready to go (this is standard procedure for any Processing library).

To get started try out the included demos in the "examples" subfolder...

For further reference about the general Processing library handling, also see here:
http://processing.org/reference/libraries/

Okay, I'm trying to be helpful here, but I dare to say there's some misunderstanding here. The readme file in the download has the one error in that the instructions incorrectly refer to a "geomutils" folder, which was the old name of the "toxiclibscore" package and that occurrence has somehow slipped correction. This is an oversight on my behalf and will be fixed with the next release. However, the steps I outlined in the post above are correct (and hundred times verified by myself and lots of other people) and I'm trying to understand where your problem still lies...

Therefore can you please let me know the following:

* your platform & exact version (OSX, Windows, Linux, if OSX Intel or PPC)
* your java version

The libraries require at least Java 1.5 or newer. If you're on OSX 10.4 you might still have 1.4.2 as default, check your Java Preferences in Applications > Utilities and see if JavaSE 5.0 (or 6.0) is listed (and if so, change the order so that it's on top of the list)

Also, you're still referring to a "geomutils" folder. When you downloaded the "toxiclibscore-0014.zip" archive from the URL above & unzipped it, you should have ended up with a folder called "toxiclibscore" only. Don't rename this folder, but simply drag it into the "libraries" folder and restart Processing.

Did you ever install any other Processing library?

Can you should, please, the exact path to your sketch, and the path to the toxi's library? Thanks.

Just what I was thinking...
Well, I fear I don't know how Processing is set up on Macs; but it looks like you put your sketches in Processing's install dir, which is basically a bad idea: you should separate programs and their data. Otherwise you might have a nasty surprise when you upgrade.
You have examples coming with the program, but you shouldn't mix your own sketches with them.

toxi says default sketchbook folder is Documents/Processing
The library page says: "To find the Processing sketchbook location on your computer, open the Preferences window from the Processing application and look for the "Sketchbook location" item at the top." This dialog also allows you to change this folder (need a restart).

Reminder on vocabulary: the sketchbook is the place where you put all your sketches. A sketch is a folder (in your sketchbook!) holding the .pde file(s), the data folder if any, etc.

So you are supposed to make a 'libraries' folder in the sketchbook, at the same level as your other sketches. Not in the sketch's folder itself.

I understand newcomers might trip on the vocabulary, that's why I ask for exact paths, not "~/…/Processing/<sketchbook>/libraries" which is too simplified...

HTH.

You have to use save() (at display DPI, so you must increase sketch's size if you want to do 300dpi) or built-in PDF library.

So glad this is resolved & had actually nothing todo with my libs phew! I seemed to recall there was a sticky thread somewhere about the proper setup & usage of that main library folder, however I can't seem to find it anymore. I agree though, this should be made more prominent & I'll try to expand on my library instructions too...
