I am moving from the WebIDE to get to learn Workbench. I initialised a new project. Installed all the libraries, copied all the src files from a downloaded zip from the WebIDE. 1st compile error /Users/shanevanj/Documents/Workbench/fMonX/fMonX1/lib/ArduinoJson/src/ArduinoJson/Strings/SizedFlashStr…

So just to close this thread down - the fix is as follows include <Arduino.h> before the <ArduinoJson.h> library and add in a definition as follows #include <Arduino.h> #define ARDUINOJSON_ENABLE_PROGMEM 0 #include <ArduinoJson.h>

if you are comfortable sharing your source or simplified version of it that reproduces the error, i’d be happy to take a look. in the meantime, things to double-check are: platform (photon, argon, etc) and Device OS version - make sure you have them set the same way across both WebIDE and Workbench…

[image] shanevanj: error: 'strncmp_P' was not declared in this scope return -strncmp_P(other, reinterpret_cast<const char*>(_str), _size); As @m_m already asked, what device OS version are you targeting? These Arduino compatibility macros got introduced later on in history.

Easy to reproduce. Create new project, install ArduinoJSON libray. Open lib/ArduinoJson/examplesJsonParserExample. Copy contents to your new project .ino file and compile. error produced is /Users/shanevanj/Documents/Workbench/ArduinoJson/Test/lib/ArduinoJson/src/ArduinoJson/Strings/SizedFlashStri…

Can someone log as a bug after verifying the above (or not if thats the case - I am still a noob at this and may have got it wrong)

sounds like you are hitting this: [image] ArduinoJson Example Fails Troubleshooting I tried this example Got this error ===================== Processing json.ino Checking library ArduinoJson… Installing library ArduinoJson 6.10.0 to lib/ArduinoJson … Library Ardui…

Essentially I came to the same conclusion as @ScruffR did in that thread.The definition above is missing from the Arduino compatibility macros in each deviceOS release fro workbench. Once you add it in it all works. It needs to be be logged as an issue for the workbench team to add in this macro.

As it seems pgmspace.h is not included when not also including Arduino.h but for existing libraries that were ported for Particle before Arduino.h was added to the build farms that’s suboptimal :wink: But if you #include <Arduino.h> before any dependent headers you should be good.

do any of the suggested fixes in that thread work for you?
