I downloaded a couple of sample apps for the Adafruit 2.4" TFT display. I can compile on the Web IDE, but it keeps failing in Workbench. I have deleted all of the example .ino files. Below is the output from Workbench. Suggestions?

Multi-definitions are probably caused by two interfering libraries.  
You seem to have `Adafruit_GFX` _ **and** _ `Adafruit_mfGFX` installed in your project - you need to get rid of one of them.

Which library are you using for your display?

In case I messed up, I delete all of the included library files. I then copied the source from the Web example `touchpaintfeatherwing.ino` into the src file in Workbench. I looked at the source and attempted to include the 3 specified libraries, but it could not find the `Adafruit_STMPE610` library. I found the `Adafruit_STMPE610RK` version of the library and decided to include it, but it also included the `Adafruit_mfGFX library` which was not referenced in the src file. Thinking I was making a logical change, I deleted the `GFX` library and modified the `#include` to be `#include <Adafruit_mfGFX>` file and modified the `project.properties` file to reflect these changes, but I’m still getting the errors (too long to include), but ending with:

You do mention `Adafruit_mfGFX` and `Adafruit_GFX` but have you also removed `Adafruit_GFX_RK` as this is now mentioned in your error log.

As for the reason why @rickkas7 has included another GFX library in his `Adafruit_STMPE610RK` lib I’d have to defer to him.

Thanks @ScruffR for your thoughts. I won’t waste any more of your time. I was simply trying to determine all the functionality I have in this TFT display and it’s pretty cool. I was able to do all of my testing via the Web IDE and merely wondered why I had so much trouble using Workbench–uncommon from my experience with the same app.

The Adafruit\_STMPE610\_RK library doesn’t include any other libraries. I don’t include Adafruit\_mfGFX in any of my libraries or ports.

Aaaahhh…installing the `Adafruit_ILI9341` library resulted in the `Adafruit_mfGFX ` being installed automatically…

So, my fundamental question is why source copied from the Web IDE and pasted into a source file in the Workbench, followed by including the libraries referenced in the source will compile on the Web IDE, but not in Workbench.

hard to say without looking at the specific project. are you able to share it?

I was using the `touchpoint_featherwing.ino` example in the `ADAFRUITTOUCHSCREENFEATHERWINGRK` library via the Web IDE (Build). I can compile it in the web and when using the Workbench, I can also do a cloud compile. However, if I try to do a local compile, I have to first add the libraries listed in the source. It can’t find the `Adafruit_STMPE610.h` library, so I used the `Adafruit_STMPE610RK` library. However, no matter what I try, I keep getting version of the errors listed above. The first question is why it can’t find the `Adafruit_STMPE610` library. I hope that’s what you meant by “sharing” the project.

Here’s the source for the application:

ah, ok. i’m able to compile using the following steps:

1. Run the `Particle: Create Project` command ([docs](https://docs.particle.io/tutorials/developer-tools/workbench/#working-with-particle-projects))
2. Once your new project loads, run the `Particle: Install Library` command then input `AdafruitTouchscreenFeatherWingRK` and press `<enter>`
3. Copy the contents of `./lib/AdafruitTouchscreenFeatherWingRK/examples/touchpaint_featherwing/touchpaint_featherwing.ino` to `./src/<your-project-name>.ino`
4. Run the `Particle: Compile application (local)` build task ([docs](https://docs.particle.io/tutorials/developer-tools/workbench/#local-build-and-flash))

I’m not sure why you are hitting problems - have you tried running the `Particle: Clean application and DeviceOS (local)` task?

Beyond that, perhaps compare my project (see `.zip` below) files and layout with yours?

@m_m - So…that worked for me, too. How was I suppose to know that I should simply include the …RK library? Was it due to the fact that the example was in that library listing? Perhaps just another thing that’s not too obvious to me.

Thanks so much for your assistance. I would not have figured that out my myself!

always interested in suggestions on how to make this stuff more intuitive. in the meantime, have you checked out our tutorial videos?

No, I had not viewed that video, but I’ve used numerous libraries in the past and even created and published one for NTC thermistors. What confused me is why the application would compile in the Web IDE and in the cloud via Workbench without issue, but I couldn’t find and install the library for a local compile. Furthermore, it was not obvious to me that I needed to install the …RK library in lieu of the three libraries listed in the application includes. Oh well…mystery solved. I’m not complaining above…simply conveying my confusion.

As always you guys are an amazing resource and have enabled me to do some great things with Particle devices. Thanks!
