My system is ubuntu 20.1
since I think esp-open-sdk is old, I've got the latest toolchain from here. https://github.com/espressif/ESP8266_RTOS_SDK. And I have done the path as well.

$ xtensa-lx106-elf-gcc --version
xtensa-lx106-elf-gcc (crosstool-NG esp-2020r3-49-gd5524c1) 8.4.0

now I think toolchain has been installed.
then
$ git clone https://github.com/micropython/micropython.git
$ cd ports/unix
$ make submodules
$ make
$ ./micropython, got it.
$ make test
801 tests performed (21040 individual testcases)
801 tests passed

then
cd ..
cd esp8266
$ make submodules
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
$ make V=1 submodules
Updating submodules: lib/axtls lib/berkeley-db-1.xx
git submodule update --init ../../lib/axtls ../../lib/berkeley-db-1.xx
$ make V=1
OK, IT SHOWS THE ERRORS:

It seems like toolchain's problem, but I've still tried the old way
$ make V=1 axtls
make: *** No rule to make target 'axlts'. Stop.

and I've tried
$ git submodule update --init
it doesn't work as well.

So, do I have to use esp-open-sdk as the toolchain in esp8266?
Those has been added into /etc/profile

export PATH=~/ESP/xtensa-lx106-elf-gcc8_4_0-esp-2020r3-linux-amd64/xtensa-lx106-elf/bin:$PATH
export IDF_PATH=~/ESP/esp8266/ESP8266_RTOS_SDK
export ESPIDF=~/ESP/esp8266/ESP8266_RTOS_SDK
export PATH=/home/kevin/micropython/micropython/ports/unix:$PATH

I'm totally confused now. SOS.

I just want to tell you guys, I just try the toolchain from esp-open-sdk, version=4.8.x , now it's working for me, I will try to compile esp32 with the latest toolchain and the older one, later.

been tested. If you want to compile esp32, get your toolchain from there:

Hi kevinscorpionfox,

I would like to use ESP8266_RTOS_SDK. Can you be more specific what you have done exactly. You mentioned some problems

I'm totally confused now. SOS.

Thanks,

Dude, that's my "be more specific", DO NOT USE ESP8266_RTOS_SDK when you try to complie micropython project in ESP8266. I wasted couple days becasuse of this.
