[SOLVED] Confused on building Espruino for ESP8266

Hi,

I'm trying to get the latest build of Espruino but I'm not able to build from source.

As README says, I built esp-open-sdk without errors. I also cloned espressif-sdk from https://github.com/espressif/ESP8266_RTOS_SDK as stated here. As far as I could understand, there is no need to build espressif's SDK.

Then I used following script to call make:

#! /bin/bash
R=/home/ceremcem/embedded

export ESP8266_BOARD=1
[#export](https://forum.espruino.com/search/?q=%23export) FLASH_4MB=1
export ESP8266_SDK_ROOT=${R}/ESP8266_RTOS_SDK
export PATH=$PATH:${R}/esp-open-sdk/xtensa-lx106-elf/bin/
export COMPORT=/dev/ttyUSB0
make $*

No success:

$ ./run-make 
CC targets/esp8266/user_main.o
targets/esp8266/user_main.c:17:28: fatal error: user_interface.h: No such file or directory
 [#include](https://forum.espruino.com/search/?q=%23include) <user_interface.h>
                            ^
compilation terminated.
Makefile:1705: recipe for target 'targets/esp8266/user_main.o' failed
make: *** [targets/esp8266/user_main.o] Error 1

Just moved this to the ESP8266 section...

I guess that value for ESP8266_SDK_ROOT is not correct.

ls -l /home/ceremcem/embedded/ESP8266_RTOS_SDK/include/user_interface.h

Well, I changed the export line to:

export ESP8266_SDK_ROOT="${R}/esp-espressif-sdk/ESP8266_NONOS_SDK_V1.5.3_16_04_18/ESP8266_NONOS_SDK"

and the problem went away. Now we have a new problem of lwip:

ldcannot : findcannot -llwip_536 find
 -llwip_536

I think there is a reference to a forum post, and that refers to where to get that library, sorry a bit vague but don't have the info to hand at the moment

You mean this one and the lwip link points to here. I unzipped the archieve and moved liblwip_536.a to ${ESP8266_SDK_ROOT}/lib/. Now we progressed and new error is this:

cp: cannot stat ‘/home/ceremcem/embedded/esp-espressif-sdk/ESP8266_NONOS_SDK_V1.5.3_16_04_18/ESP8266_NONOS_SDK/bin/boot_v1.4(b1).bin’: No such file or directory

I simply created a symlink to bin/boot_v1.5.bin, so the result is:

and the problem went away. Now we have a new problem of lwip:

https://github.com/espruino/Espruino/blob/master/README_Building.md#for-esp8266

You seem to be mixing SDK 1.5.3 and lwip from SDK 1.5.0. YMMV...

Unless you're trying to fix some specific problem using 1.5.3 I suggest using 1.5.0 and waiting for 1.5.4: http://bbs.espressif.com/viewtopic.php?f=7&t=2104

I found SDK 1.5.0 and liblwip_536_for_ESP8266_NONOS_SDK_V1.5.0.zip, downloaded them, extracted lwip_....zip and copied the liblwip_536.a file into [SDK-1.5.0]/lib folder. It seems everything went OK. Result binaries are here, FYI

@tve if it weren't for you to warn me I would struggle with the following error:

Uncaught process.memory() didn't contain information about flash memory
