Hi @twillert. I'm sorry that you're having a problem compiling. I'm going to ask you to post some additional information that might help us to identify the problem. * * * ❗ NOTE: These instructions will not solve the problem. They are only intended to gather more information which might provide a clue that eventually leads to a solution. * * * Please do this: 1. Select **File \> Preferences** from the Arduino IDE menus. 2. Check the box next to " **Show verbose output during: ☐ compilation**". 3. Click the **OK** button. 4. Select **Sketch \> Verify/Compile** from the Arduino IDE menus. 5. Wait for the compilation to fail. 6. You will see a " **Compilation error: ...**" notification at the bottom right corner of the Arduino IDE window. Click the **COPY ERROR MESSAGES** button on that notification. 7. Open a forum reply here by clicking the **Reply** button. 8. Click the **``** icon on the post composer toolbar. This will add the forum's code block markup ( **`````** ) to your reply to make sure the error messages are correctly formatted. ![Code tags icon on toolbar](https://europe1.discourse-cdn.com/arduino/original/4X/f/3/4/f34b0ef2ecd107da4bf127b3c0bc1c28569e7fe0.png) 9. Press **Ctrl+V**. This will [paste](https://lifehacker.com/how-to-copy-cut-and-paste-for-beginners-5801525) the compilation output into the code block. 10. Move the cursor outside of the code tags before you add any additional text to your reply. 11. Click the **Reply** button to post the output. * * * In case the output is longer than the forum software will allow to be added to a post, you can instead save it to a `.txt` file and then attach that file to a reply here: 1. Open any text editor program. 2. [Paste](https://lifehacker.com/how-to-copy-cut-and-paste-for-beginners-5801525) the copied output into the text editor. 3. Save the file in `.txt` format. 4. Open a forum reply here by clicking the **Reply** button. 5. Click the "Upload" icon ( ![Upload icon](https://europe1.discourse-cdn.com/arduino/original/4X/c/0/0/c0067471d5eb440267189d84a0c94cfed541a968.png)) on the post composer toolbar: ![Upload icon on toolbar](https://europe1.discourse-cdn.com/arduino/original/4X/3/0/1/30174157d368457aa9e1c9f5fb673d691a6e1516.png) 6. Select the `.txt` file you saved. 7. Click the **Open** button. 8. Click the **Reply** button to publish the post. Alternatively, instead of using the "Upload" icon on the post composer toolbar as described in steps (5) - (7) above, you can simply drag and drop the `.txt` file onto the post composer field to attach it. ---
