Hi!
I am experimenting with a Teensy 4.1, and I have installed Teensyduino (1.8.19) along with Arduino IDE. Using macOS (Monterey 12.1).
I have been experimenting problems that seem to be related to duplicated libraries from Teensyduino and Arduino. It all started with a "'BUILTIN_SDCARD' was not declared in this scope" error while trying to use SD library. The compiler states that it finds several version of the same libraries (in the Applications/Teensyduino folder and in the ~/Arduino/libraries folder).
I have tried, for example, to erase the SD library from Arduino IDE to try to force the compiler to use the Teensyduino SD library, and it does, but now it complains "Teensy's SD library uses a custom modified copy of SdFat. Standard SdFat was mistakenly used. Arduino should print multiple libraries found for SdFat.h. To resolve this error, you will need to move or delete the copy Arduino is using, or otherwise take steps to cause Teensy's special copy of SdFat to be used.". I could maybe continue by erasing also de SdFat library from Arduino IDE, but it doesn't seem a good solution.
Both Teensyduino and Arduino IDE seem to share at least some of the configuration files, paths and libraries. I have other development boards, so I would like to keep both versions installed and updated, so the question is if there is an easy and clean way to see both environments (Teensyduino and Arduino IDE) more or less isolated to avoid this interference.
Thank you very much for any advice.
The sketch I was using was the Card Info example from the SD library:

The sketch I was using was the Card Info example from the SD library:
Code:
/*
SD card test
This example shows how use the utility libraries on which the'
SD library is based in order to get info about your SD card.
Very useful for testing a card when you're not sure whether its working or not.
The circuit:
SD card attached to SPI bus as follows:
** MOSI - pin 11 on Arduino Uno/Duemilanove/Diecimila
** MISO - pin 12 on Arduino Uno/Duemilanove/Diecimila
** CLK - pin 13 on Arduino Uno/Duemilanove/Diecimila
** CS - depends on your SD card shield or module.
Pin 4 used here for consistency with other Arduino examples
