Unable to build project due to picolibc issue.

[khanal-abhi]

Describe the bug

I recently upgraded zephyr and sdk to v4.0.90 and v17 and I cannot build even the hello world application due to issues with picolibc source. Attached is the full log of a pristine zephyr build. Please advise:

Regression

• This is a regression.

Steps to reproduce

Steps to reroduce:

1. cd zephyrproject
2. west build zephyr/samples/hello_world -b esp32s3_devkitc/esp32s3/appcpu -p

Relevant log output

west build zephyr/samples/hello_world -b esp32s3_devkitc/esp32s3/appcpu -p

Make sure you are using the Zephyr SDK version listed in zephyr/SDK_VERSION.

As @henrikbrixandersen suggested, review the SDK_VERSION file using cat zephyr/SDK_VERSION and confirm the version contained in the file match with the toolchain version.

I tried to compilate it with:

Zephyr version: 4.2.0
SDK_VERSION: 0.17.2

It worked using the same command.

To replicate this process, I changed the zephyr version to 4.0.0 (I couldn't set up for version 4.0.99). After that:

1. I went to $HOME root and move the current zephyr SDK folder to another directory.
2. Inside the directory zephyrproject/zephyr , write the command west sdkinstall , It will install the version listed on SDK_VERSION file.
3. Finally, on the root zephyrproject I tested the command west build zephyr/samples/hello_world -b esp32s3_devkitc/esp32s3/appcpu -p. The compilation was successful.

Please try these steps and let us know the results you get.

Ah ok yes this works as well. I was annoyed so started a fresh zephyr sync from scratch and that worked. Tested this out retroactively, and it works. I understand now how to follow the upgrade path for a tighter compatibility. I think this broke what has always worked for me in the past - update zephyr source and sdk (recommended one) separately. If this is the expected approach now, I don’t think this is a bug.
Thank you!
