I have had a pause in development - I come back to a know working project and recompile it and get a failure.
What could possibly have changed - has platform IO updated something - how do I know and how can I control this?
The project has an #include<freertos.h> a copied section of code from the web which worked.
Now I get the can’t find freertos.h and advice to sort out the library path.
Where is <freertos.h> in my installation and why would it now be missing.
Where is the library path and why would it have changed?
???
This is way too vague. We need at least the full error message, the platformio.ini and the file structure of your project. If the project is too big, try reproducing the error in a smaller project with similar platformio.ini.
There are a lot of errors that occurred.
The first was
src/main.cpp:9:10: fatal error: FreeRTOS.h: No such file or directory
To resolve it I added the freertos.h file to the ‘libs’ folder and add a directive build_flags = -I"lib" to find it. ( I needed to find what to do here from web help )
Subsequent to that there were then other compiler warnings preventing a successful compile requiring a change to the pio.ini
From this:
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 115200
build_flags = -I"lib"
lib_deps =
bodmer/TFT_eSPI@^2.5.23
contrem/arduino-timer@^3.0.0
bblanchon/ArduinoJson@^6.21.2 GitHub - me-no-dev/ESPAsyncWebServer: Async Web Server for ESP8266 and ESP32
ayushsharma82/AsyncElegantOTA@^2.2.7
board_build.partitions = default_16MB.csv
Essentially, the environment must have changed requiring me to amend these things which was a worry, so I get concerned that maybe tomorrow something else changes that demands my time to resolve.
Where / which folder would the <FreeRTOS.h> normally reside.
Why would it move or why would the compiler suddenly no longer find it?
The Async webserver at version 1.2.3 clearly needed updating as there was an error preventing it compiling.
The project now compiles and links although I haven’t tried it on a target.
What worries me is why these changes were needed from a stable project and how can I control what must have been updated automatically when I opened VS Code.
If FreeRTOS can’t be found, that sounds more like broken packages. Given you have not modified any PlatformIO-package internal files (in C:\Users\<user>\.platformio), I would suggest:
Delete your project-local FreeRTOS files in the lib/ folder completely
Remove any build_flags =-Ilibs reference to it in the platformio.ini
Close VSCode
Delete the C:\Users\<user>\.platformio\platforms folder
Delete the C:\Users\<user>\.platformio\packages folder
Delete the C:\Users\<user>\.platformio\.cache folder

Then a message:
Cannot validate since a PHP installation could not be found. Use the setting ‘php.validate.executablePath’ to configure the PHP executable.
The main.c file still shows the error

I wondered … so I did move it out of there .
It’s in a dropbox subfolder now…( same problem I will move it someone simple and try one more time, but this is the current output .
** EDITED ** Same result in a top level folder
Executing task: C:\Users\lumef.platformio\penv\Scripts\platformio.exe run

Well Thankyou! That fixed that particular problem
I still don’t’ know why I (we) needed that change since clearly the project compiled ok previously.
Any insight into that would of course be useful.
Edit - ESP UPDATE…
If it happened I didn’t notice… but it probably did. I’m sure there’s a way to lock a build state with a particular version… but I don’t know how.
