Arduino CLI version 0.20.2
Arduino Portenta core version 2.6.1
LinkedList library version 1.3.2

Compiles for Arduino Mega after deleting tests.cpp.

can you paste the code?

I was trying to compile the ClassList example in your repo.

Compile command: arduino-cli compile ~/Arduino/libraries/LinkedList/examples/ClassList/ClassList.pde -b arduino:mbed_portenta:envie_m7 --libraries ~/Arduino/libraries/

Hello, did you find some solution for this case? I am using an Giga r1 and when I try to compile appers me the same error output.

Thanks in advanced.

This is happening because the mbed libraries have a LinkedList structure as well, with less capabilities than this library.

I fixed it by manually editing the LinkedList.h file in this library to LinkedList_git.h and all the references inside the file to LinkedList_git instead. I then put this header file in the directory of my .ino and it works.

Hello @julianstj1 thanks a lot for shared it! That was correct, this helped me.

Can I ask how you found/knew out this? Also, what was your methodology for discovering that mbed libraries have a LinkedList structure? I'm learning more about micro-controllers and I'm curious to know because it might help me to have a better understand of how to find more features of micro-controllers :)

A better way to workaround the issue is in PR #51

I found it just using view definition in the Arduino IDE. I right clicked on my object declaration of LinkedList, and it took me to a LinkedList.h file that was somewhere in the Arduino directories for mbed giga, so I knew it was linking against the wrong file. So just changing the name so it doesn't conflict makes it work.
