Library duplicate problem

Projects Programming

I have a problem with my Arduino ide on Windows. The library only contains 2 folders but why does Arduino Ide still say duplicate library?

Please read the forum guidelines, screenshots are not welcomed here.
Please insert a full error message as a text, using a code tags.

It is impossible to read your screenshots, but I doubt I have ever done a compile/verify without a message or two about duplicate libraries. Once you understand how the hierarchal concatenating library system works you will realize those are just info messages.

This is a problem when I have emptied the libraries in the folder but the Arduino Ide still reads 2 duplicate libraries.

I know the error message is photo is prohibited, I just want to fix why the library folder is empty, Arduino Ide still reads 2 duplicate libraries

Hi @bimosora. I'm going to ask you to provide the full verbose output from a compilation.

:exclamation: This procedure is not intended to solve the problem. The purpose is to gather more information.

Please do this:

  1. Select File > Preferences... (or Arduino IDE > Settings... for macOS users) from the Arduino IDE menus.
    The "Preferences" dialog will open.
  2. Check the box next to "Show verbose output during: ☐ compile" in the "Preferences" dialog.
  3. Click the "OK" button.
    The "Preferences" dialog will close.
  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 <CODE/> 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.

  9. Press the Ctrl+V keyboard shortcut (Command+V for macOS users).
    This will paste the compilation output into the code block.
  10. Move the cursor outside of the code block markup 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.

Click here for attachment instructions

  1. Open any text editor program.
  2. Paste 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) on the post composer toolbar:
    Upload icon on toolbar

    The "Open" dialog will open.
  6. Select the .txt file you saved from the "Open" dialog.
  7. Click the "Open" button.
    The dialog will close.
  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.

There is absolutely nothing about duplicate libraries in the output you shared.

Please provide a detailed explanation of what it is that is making you think Arduino IDE is "reading 2 duplicate libraries".

I use this library in my code

ESP32-VirtualMatrixPanel-I2S-DMA.h

But on the Arduino ide instead reads this
ESP32-HUB75-MatrixPanel-I2S-DMA.h

Yes, because that file is part of the library:

https://github.com/tidbyt/ESP32-HUB75-MatrixPanel-I2S-DMA/blob/master/ESP32-HUB75-MatrixPanel-I2S-DMA.h

So this is normal and expected. You have come to an erroneous conclusion that the cause of your problem is a duplicate library.

The problem is that compilation is failing with this error message:

The library is written for use with boards that use an ESP32 microcontroller as the primary microcontroller. When compiling for one of those boards, the C++ standard library provides a header file named vector. However, if you compile for a different board, such as the boards based on the AVR microcontrollers then the standard library will not provide a header file of that name.

Unfortunately you did not follow the instructions I provided in post #6, which would have told us which board you are compiling for. So I am now forced to waste time by asking you: which board do you have selected in Arduino IDE?
