While building for a port on FreeBSD CURRENT using esp-4.3.0_20240322, I run into a sticky error:

@SB211 , please give more information on how you do this. Using crosstool-ng? (what configuration are you using and where I can see source code of crosstool-ng you are using)?

If it is not crosstool-ng, please provide a command line that was executed to configure newlib.

I suspect you building xtensa-esp32-elf toolchain that was outdated since version esp-13.2.0_20230928. At this moment only unified "[xtensa/riscv32]-esp-elf" toolchain builds are maintained that support all xtensa/riscv32 chips.

Sorry for the late response.

Using trombik/xtensa-esp32-elf toolchain for FreeBSD with FLAVOR idf52 works as expected.
