Well, toolchain is another thing on the BSD TODO list :-) You either need to have Espressif toolchain installed and in path or you can provide your own or system toolchain by hand durign build.
I am on a trip right now with my backup laptop that is not my main development workstation, sorry, but the summary is below. 1. Because FreeBSD can natively emulate Linux ELF binaries, I did a trick with support of Espressif that allows download and install Linux tools on FreeBSD with ESP-IDF. That works fine.. but it would be perfect to build and distribute also toolchain binaries for FreeBSD by Espressif. So far I have used ESP IDF Linux tools on FreeBSD for initial experiments on ESP32 and ESP32-C3. % uname -a FreeBSD 0xCFMX4 13.1-RELEASE-p2 FreeBSD 13.1-RELEASE-p2 GENERIC amd64 % ls -1 ~/.espressif/tools esp32s2ulp-elf esp32ulp-elf openocd-esp32 riscv32-esp-elf xtensa-esp32-elf xtensa-esp32s2-elf xtensa-esp32s3-elf That gives: % ./xtensa-esp32-elf-gcc -v Using built-in specs.

FreeBSD has its own ports and packages with various build toolchains for almost any target out there.
