MicroPython Compilation Error

Hi,
when I compile MicroPython on OS X (using virtual box, vagrant, git) I get this error :
Code: Select all
Use make V=1 or set BUILD_VERBOSE in your environment to increase build verbosity.
CC ets_alt_task.c
In file included from ets_alt_task.c:5:0:
/home/vagrant/esp-open-sdk/xtensa-lx106-elf/xtensa-lx106-elf/sysroot/usr/include/esp_sdk_ver.h:1:1: error: expected identifier or '(' before '-' token
-e #undef ESP_SDK_VERSION
^
/home/vagrant/esp-open-sdk/xtensa-lx106-elf/xtensa-lx106-elf/sysroot/usr/include/esp_sdk_ver.h:1:4: error: stray '#' in program
-e #undef ESP_SDK_VERSION
^
make: *** [build/ets_alt_task.o] Error 1
vagrant@vagrant-ubuntu-trusty-64:~/micropython/esp8266$
Can someone help me?
Thanks.

There were recent changes in the toolchain. Please rebuild and keep an eye on that.
Dirty solution: Edit ~/esp-open-sdk/xtensa-lx106-elf/xtensa-lx106-elf/sysroot/usr/include/esp_sdk_ver.h
Code: Select all
- -e #undef ESP_SDK_VERSION
+ #undef ESP_SDK_VERSION

how do you change it using the terminal?

Sorry if I wasn't clear. You used esp-open-sdk to build the toolchain, didn't you? So best thing you can do is to rebuild the toolchain according to
https://github.com/pfalcon/esp-open-sdk#pulling-updates. Compiling MicroPython should work after that.
The dirty (and therefore not recommended) solution is to edit the above mentioned file in above mentioned manner on your host by using a file editor of your choice (and then (try to) compile MicroPython).

Same problem on Ubuntu 15.10 and everything is current. Making that change in ~/esp-open-sdk/xtensa-lx106-elf/xtensa-lx106-elf/sysroot/usr/include/esp_sdk_ver.h did allow it to compile although when I flashed the esp8266 i get to the REPL and it freezes with the following -- not sure if it's related to changing esp_sdk_ver.h or completely unrelated:
Code: Select all
lbl▒▒l▒could not find module 'boot'

A little more info -- now getting the below. Understanding that it is very early in the release of the firmware, if it's better just to sit tight and wait a bit, happy to do that. Posting if it is useful to anyone.

Off-topic: I wouldn't expect the present MicroPython/ESP8266 Github publications to be functioning software releases. The developers are doing their work "in public" (due to achieved KS stretch goal). What has been "released" is functioning ALPHA stage firmware as an isolated application with PoC character which certain KS backers have received by mail.
On-topic: I can confirm that the latest GitHub commit for MicroPython/ESP8266 leads to the aforementioned suboptimal result
Alas, we might have to wait a week for any substantial changes because of No. 5 in
https://www.kickstarter.com/projects/21 ... ts/1508562 (I wish the guys a nice holiday!).

As per #1895, Stefan Wendler's solution worked for me:
in "esp8266/esp_mphal.h" change:
#define UART_TASK_ID 0
to
#define UART_TASK_ID 1
