undefined __errno build problem - Cseb84 - 05-06-2025
Hi,
When i try to build my stm32 project, i get the error below:
"In function `sqrtf': wf_sqrt.c
.text.sqrtf+0x80): undefined reference to `__errno' "How can i fix this error?

I just tried it here without any problems.
My guess is that you don't use the right libraries. Are you using Newlib Nano branch?
