fatal error: SmartLEDShieldV4.h: No such file or directory compilation terminated.

[PeideSuperman]

I am doing this SmartMatrix Animated GIF Player project. I am using Teensy 3.2 and SmartLEDShieldV4. I do exactly what the tutorial says but I found trouble with the coding part as far as I can tell. When I try to upload the code there is an error occur:

Arduino: 1.8.7 (Mac OS X), TD: 1.44, Board: "Teensy 3.2 / 3.1, Serial, 48 MHz, Faster, US English"

/var/folders/b2/jvwmq0k57jb1nnv1ns3pc7b40000gn/T/arduino_modified_sketch_14655/AnimatedGIFs.ino:60:57: fatal error: SmartLEDShieldV4.h: No such file or directory compilation terminated. Error compiling for board Teensy 3.2 / 3.1.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Thanks!

I happened to come across this when looking for something else. That Arduino compile error is common when a library is not installed in the correct folder. It sounds like you might not have installed the SmartMatrix library in the correct location on your computer if SmartLEDShieldV4.h is not recognized. When testing this out on on a Mac iOS v10.13.6 (with the Arduino v1.8.7 and Teensyduino v1.44), I had no issues compiling the AnimatedGIF.ino file. You can obtain the associated library through the Arduino Library Manager from the menu by selecting Sketch > Include Library > Manage Libraries.... Search for SmartMatrix3.

Otherwise, I would try uninstall/reinstall the:

• Arduino IDE
• Teensyduino add-on
• SmartMatrix Library

Thank you for your help. As you said, I have the SmartMatrix3 installed but more errors occur:

Looks like you have multiple SmartMatrix Library copies:

I deleted one of them.

Which one? Maybe you deleted the wrong one. You might just want to delete both, and use the Arduino Library Manager to download SmartMatrix3 (and not SmartMatrix_32x32)

Thanks to your help, I download the latest library and the problem solves.
