Teensy 3.2 and 4.0 don't work with Arduino IDE 2.1.1

[Russ76]

Issue template

• Hardware description:
• Ubuntu laptop HP Ryzen 7, Ros Humble
• RTOS:
• Teensy 3.2 and 4.0
• Installation type:
• Arduino IDE 2.1.1 with Teensyduino installed
• Version or commit hash:
• Downloaded latest Microros zip file and loaded library into sketch

Steps to reproduce the issue

Expected behavior

That program would compile and upload to Teensy

Actual behavior

IDE complains of the precompiled libraries. I installed the platform.txt file under /home/.arduino15/packages/teensy/hardware/avr/1.58.1

I am unable to find any Arduino/hardware/sam folder.

Additional information

This error is related to building the micro-ROS library with a different version of GCC. micro-ROS for teensy are built using with this GCC since #1482.

Could you check:

• It your local GCC match the one used by micro-ROS?
• Does it works if you checkout a commit previous to micro-ROS Library auto-update 06-02-2023 06:18 #1282, for example d993b12 ?

[Russ76]

Thanks. My local GCC version is 11.3.0
I don't see the version number in the Micro-ROS page.
I tried using the Micro-ROS Humble zip file from May, in the IDE, but it failed uploading with the same errors.
Oh, it was from last year. I also tried newer Humble version, 2.0.7, but same errors!

[pablogs9]

We just updated the Teensy support recently: #1482

Could you install a fresh Arduino + Teensy environment (latest versions), and recheck?

[Russ76]

I downloaded the latest Arduino IDE, Teensyduino, and MicroROS but it still comes up with same error when trying to compile the program.
The errors end in "undefined reference to `__locale_ctype_ptr'

[pablogs9]

I will take a look tomorrow if I have a slot. Will report here.

[pablogs9]

I have just tested this locally and it works ok with the latest teensy package: https://www.pjrc.com/teensy/td_download.html

[Russ76]

I did a complete new install and followed all the rules. I still get this error when trying to compile the program. Could it be because I have Humble installed, that the latest MicroROS is Iron? My Humble install has been updated, more than once. And this Teensy 4.0 loads the Blink program just file.

[pablogs9]

Can you try a /home/russ/.arduino15/packages/teensy/tools/teensy-compile/11.3.1/arm/bin/../lib/gcc/arm-none-eabi/11.3.1/../../../../arm-none-eabi/bin/gcc --version and paste here the answer?

I tried a new computer to do it, too. New hardware, 4 core Celeron unit, new Jammy install, Humble with dev tools, MircoROS installed and it ran PingPong. Then Arduino IDE 2.1.1, Added the Udev rules, then Teensyduino, changed the hidden platform.txt file. Added Iron MicroROS library to a sketch, it loaded. Chose an example from the list, the MicroROS publisher. Tried to compile. Same error!

Hi @Russ76, I have the same issue, with Arduino IDE 2.2.1 and trying to find a solution. Have you managed to fix this issue?

[Russ76]

Yes, the problem vanished with updated versions. Be sure to use the newest versions, and copy over the text file. You will see the example code come up to choose from.

[adityakamath]

Thanks! I installed updated versions for everything, but still had issues compiling on Windows. I compiled on WSL2 and it worked fine. Problem solved, for now at least :)

[Russ76]

This issue is resolved.
