Hello.

I think, that will be the first step in the right direction (using the official eps-idf).
Since I didn't come along with the salvation of the linker error reported earlier, I
switched back to an older project from January this year. It is also based on the
official FreeBSD Arduino 1.8.5 port and the xtensa compiler 5.2.0 from ports, but I used
within sketchbook/hardware/esp32 the esp32 git branch release/v1.0 instead of master on
which I faced the crt1-sim.o error. The goal is to compile HyperionLED (as a side
product) with the recommended libraries for this project.
It doesn't compile with ESP32 branch release/v1.0, the error is now

[...]
libraries/FastLED/src/platforms/esp/32/clockless_rmt_esp32.h:149:33: error:
'cpu_hal_get_cycle_count' was not declared ...
[...]

which lead me to the conclusion that a more recent version is required. With the recent
version of ESP32 stuff in place, I face the mentioned crt1-sim.o error.

Searching the web for that error leads to a discrepancy of ESP-IDF and the compiler stuff.

I'll try the original esp-idf as you suggested (it is a pity it is backed by cmake, I'm
not quite familiar with cmake yet).

Any advice is highly appreciated.

Kind regards,
