ok i found . I need to build toolchain But when I compile it ./ct-ng xtensa-esp32-elf , ./ct-ng build got "[INFO] Installing pass-2 core C gcc compiler" and it do not response at any time .I wait 12 hours.))

Ok I run Arduino, so I want to add library for adruino ide --- ESP32 pi@orangepipc2:/opt/arduino-1.8.5/hardware/espressif/esp32/tools$ python get.py System: Linux, Info: Linux-4.14.14-sunxi64-aarch64-with-Ubuntu-16.04-xenial Platform: x86_64-pc-linux-gnu Downloading xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz Done Extracting xtensa-esp32-elf-linux64-1.22.0-80-g6c4433a-5.2.0.tar.gz Downloading mkspiffs-0.2.1-linux64.tar.gz Done Extracting mkspiffs-0.2.1-linux64.tar.gz Renaming mkspiffs-0.2.1-linux64 to mkspiffs Done pi@orangepipc2:/opt/arduino-1.8.5/hardware/espressif/esp32/tools$ But when I compile it on arduino ide eroor: fork/exec /opt/arduino-1.8.5/hardware/espressif/esp32/tools/xtensa-esp32-elf/bin/xtensa-esp32-elf-g++: exec format error Error compiling for board ESP32 Dev Module. What is problem?

Anybody know how install ARDUINO IDE on ARMBIAN orange pi pc 2? Can I drop tar archive to home/pi/arduino
