ESP32 build failure

[LaszloLango]

I tried to build ZJS for ESP32, but I ran into some issues. It looks like newlib is not supported by the Zephyr OS on ESP32. I've tried to edit src/zjs_common.json, but it did not help. I tried to add CONFIG_NEWLIB_LIBC=n", but it leads to other linker errors (missing libc and libm functions). I also tried to change the KConfig in the OS, to build as a native app, so libc functions where found by the linker, but it lead to an other linker error. Is there any workaround? Is it possible to build ZJS without external libc?
