blinke dont link, error __lock__libc_recursive_mutex

[higginsa1]

Hello, I need some assistance.
I’ve completely reinstalled my system and am now using VirtualBox with Ubuntu Mint Xfce. The Zephyr project is running inside a virtual Python environment (.venv).
The setup includes:

Zephyr SDK: Version 0.17.1

Zephyr Codebase: Version 4.1

SDK Installation Path: /opt/

After completing the installation, I attempted to compile the blinky sample. However, I encountered a compiler error in the lock.c file. The code is completely untouched – I haven’t made any changes.

I suspect that I may have missed something during the installation or that some component hasn’t been properly set up.
Any guidance on troubleshooting this issue or verifying the installation would be greatly appreciated!

Hi @higginsa1 ,
I have also found that the latest Zephyr SDK v0.17.1 is not compatible with Zephyr v4.1, and I have seen similar build errors. I suggest if you are developing with Zephyr v4.1, then use Zephyr SDK v0.17.0. Or to use the latest Zephyr SDK v0.17.1, then move to the latest main branch in the Zephyr repo.

Best regards

I believe the issue is resolved. I re-initialized everything from scratch, and now I can successfully build the Blinky example.

Many thanks!
