PlatformIO can not compile espfs_image.c not found

[michox]

Hi I am trying to compile your example code in platformio and get the following error
Compiling .pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs.c.o
*** [.pio\build\esp32doit-devkit-v1.pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs_image.c.o] Source .pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs_image.c' not found, needed by target .pio\build\esp32doit-devkit-v1.pio\build\esp32doit-devkit-v1\esp-idf\espfs\src\espfs_image.c.o'.

I have no idea what that means and how to fix it, some guidance would be greatly appreciated

Thanks for the report.
I have not tried to build this with Plaformio before, but I would like to try it and support it.

First, please provide some info about your setup:
Environment, ESP-IDF version, ESP32 or ESP8266.

Also please write a short step-by-step instruction of how you setup and build this example on Platformio and I'll give it a try. When we get it working I'll add your instructions to our readme.

I am on an esp32doit devkit v1 with the latest espressif 32 1.12.1
here is what I did:

• create an empty project in platformIO
• clone the example to an empty folder and run git submodule update --init --recursive
• copy the content into the platformIO project and copy the files from main into src.

I am not really experienced with the ESP-IDF so I might have forgotten or overlooked something major...

I see. Well it seems this example project (esphttpd-freertos) is not setup like a platformio project.
I'll have to do some searching to find out how platformio manages components which are outside of ESP-IDF.

Are you dead-set on using platformio?
There is also the ESP-IDF Explorer plugin for VSCode which provides some help and tools. It manages ESP-IDF projects in the normal way (not like platformio, not like arduino, etc...).
I expect this project should work fine in that environment. I'm installing it myself and it is downloading all the necessary tools and libraries...

Ok I can confirm I get the same error as you when trying to build on platformio.

The issue seems to be that a build step is missing, the espfs image is not generated before the build looks for it, expecting it to be espfs_image.c. I'm new to CMake so I need some help troubleshooting this. @jkent any ideas?

BTW I added src_dir = main to platformio.ini so I don't have to rename the "main" folder to "src":

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
;   Advanced options: extra scripting
;
; Please visit documentation for the other options and examples
; https://docs.platformio.org/page/projectconf.html
[platformio]
src_dir = main

[env:esp32-evb]
platform = espressif32
board = esp32-evb
framework = espidf

When we get this working we can just add platformio.ini file to this repo and it should work out-of-the-box in that environment.

I'll keep this in my inbox to review when I have more time. I'm not very familiar with PlatformIO; I know its an alternate environment for Arduino development though.

Hi jkent,
are there any news on that? I would like to use your code in an bigger PlatformIO project.
Thx for reply in advance,
jomjol

Sorry, no progress has been made on this. I'm too busy with other things at this time.
