Compilation error with Feather M4 CAN: `CANSAME5x.cpp:12:10: fatal error: same51.h: No such file or directory`

[gromain]

• Arduino board: Feather M4 CAN

• Arduino IDE version: 1.8.13

• Steps to reproduce the problem:

1. Install Arduino SAMD boards, version 1.8.11
2. Install Adafruit SAMD boards, version 1.6.7
3. Install library CAN Adafruit Fork from Library Manager, version 1.1.0
4. Choose board Adafruit Feather M4 CAN (SAME51)
5. Open example CANSender
6. Compile

The error message displayed is quite clear: Arduino/libraries/CAN_Adafruit_Fork/src/CANSAME5x.cpp:12:10: fatal error: same51.h: No such file or directory

Arduino: 1.8.13 (Linux), Board: "Adafruit Feather M4 CAN (SAME51), Enabled, 120 MHz (standard), Small (-Os) (standard), 50 MHz (standard), Arduino, Off"

I'm having the same issue. Before finding your post here, I started a thread on the Adafruit forum. You can track it here:
https://forums.adafruit.com/viewtopic.php?f=57&t=178976&p=871427#p871427

I was able to get the code to compile and upload by rolling back the IDE board support packages to older versions. Try reverting to Arduino SAMD Boards v1.6.11 and Adafruit SAMD Boards v.1.6.5 and see if that gets things working.

Then the next step will be to find exactly which board+library combination breaks compatibility so that everything can work at the most recent version.

Hi,

Following your lead (pun intended) I managed to find the commit that removed the elusive same51.h. It's at 1870cef and comes from this Pull Request: #291

Not sure who here is going to fix the issue. I'm going to boldly go ahead and tag @jepler and @ladyada .

[ladyada]

oh nooo! yes i just verified that it no longer compiles. moving to arduino core

[ladyada]

@hathach can you take a look

@gromain you can use a previous release of adafruit samd until it is fixed

[gromain]

Thanks for the (super)quick update! That's what I was planning to do in the meantime!

[hathach]

This issue will be fixed by adafruit/arduino-CAN#5 . The #291 put the same51.h as part of sam.h which is included by default when Arduino.h is include. I.e we don't ever need to manually include same51.h. It is just a left over bug from the migration. Thank you for your issue, once PR is merged, we will release the library shortly afterwards.

[gromain]

Awesome! Thanks a lot!
