ArduinoStringAdapter.hpp:7:10: fatal error: WString.h: No such file or directory #1381

Closed youcangetme closed 4 years ago

youcangetme commented 4 years ago

I am compiling for the new Teknic ClearCore using the Arduino wrappers and the Arduino IDE. It is pretty spot of Arduino compatible with a few exceptions. The architecture is described as "32-bit ARM Cortex M4F processor operating at 120MHz with 512kB FLASH and 192kB RAM. DSP and floating point instruction sets."

Here is the error I get

` In file included from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson/Strings/StringAdapters.hpp:16:0, from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson/Misc/SerializedValue.hpp:7, from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson/Variant/VariantData.hpp:8, from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson/Variant/SlotFunctions.hpp:8, from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson/Array/ArrayIterator.hpp:7, from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson/Array/ArrayRef.hpp:8, from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson.hpp:17, from C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson.h:9, from C:\Users\youca\AppData\Local\Temp\arduino_modified_sketch_599557\JsonConfigFile.ino:22: C:\Users\youca\Documents\Arduino\libraries\ArduinoJson\src/ArduinoJson/Strings/ArduinoStringAdapter.hpp:7:10: fatal error: WString.h: No such file or directory

include 

      ^~~~~~~~~~~

compilation terminated. exit status 1 Error compiling for board Teknic ClearCore.`

I tried the usual workaround and included said libs directly in the same folder with no luck. This is just including the ArduinoJson.h so if I take it out all of these errors disappear.

I am sure this is pilot error and if somebody could give me direction as to what I am doing wrong it would be great. Thanks!

Hi @youcangetme,

Thank you very much for reporting this issue.

Every Arduino-compatible core has a WString.h that contains the definition of the String class. Unfortunately, Teknic ClearCore renamed this file to ArduinoString.h.

To me, this is a mistake from Teknic and they must align their file names to the official ones; otherwise, they cannot claim to be Arduino-compatible. @youcangetme, can you contact Teknic support to report this issue?

Best regards, Benoit

I spoke too quickly.

I just discovered that Arduino team has deprecated the WString.h header:

// including WString.h is deprecated, for all future projects use Arduino.h instead

I'll modify ArduinoJson to include Arduino.h instead.

The fix is available in the 6.x branch and will be available in the next release.

However, there is still an error when compiling for Teknic ClearCore:

arduino/api/deprecated-avr-comp/avr/pgmspace.h:107:49: error: 'const void*' is not a pointer-to-object type
 #define pgm_read_ptr(addr) (*(const void *)(addr))
                                                 ^

This is due to a bug in the hardware-independent core.

Until this bug is fixed, you can either:

Thanks again for reporting this issue 👍

Thanks @bblanchon ! This is progress so I am happy. I tried the other JSON libs and your's is the best license and the best code wise. Thank you for your time and help! I will try some of the work around and see if I can get past this.

youcangetme commented 4 years ago

@bblanchon I used the follow and got it to compile. Thank you for helping!

`#define ARDUINOJSON_ENABLE_PROGMEM 0
