Could anyone help me please?

Hi,

Since 5.13.2 update in Arduino IDE can't compile having 'StaticJsonBuffer' does not name a type
Back to 5.13.1: it's ok.

Coding for MKR GSM 1400 (Samd21), code as simple as : 

StaticJsonBuffer<1000> jsonBuffer;
const JsonObject& root = jsonBuffer.parseObject(body);

alert1 = Alert(root["limit1"], root["hyst1"]);
alert2 = Alert(root["limit2"], root["hyst2"]);

startTime = root["start"];
stopTime = root["stop"];

Thanks.

Why closing ? The issue still exists

Marcussacapuces91 picture Marcussacapuces91 on 9 Jun 2018

Seems to be som troubles with namespaces :

  • namespace Internals
  • namespace ArduinoJson

But not only, I also have compiling errors like : 

xxx\Arduino\libraries\ArduinoJson\src/ArduinoJson/Json/./../Numbers/../Polyfills/math.hpp:10:6: error: expected unqualified-id before 'sizeof'
 bool isnan(T x) {
      ^

@chegewara rename the issue with something like "major regressions in 5.13.2"
Sorry for you @bblanchon (encore du travail :-) )
Thanks anyway for the very usefull lib.

Sorry about that, I'll fix this ASAP.
Meanwhile, please use 5.13.1.

Hi,

In fact I digged deeper in that point, it seem鈥檚 5.13.2 is fine, just 6.0.0 beta have it聽!
I do not understand why 6.0.0 beta is published in ArduinoIDE, as it is a beta.

Regards,

Marc

This bug is fixed in version 6.0.1

I still get this error with version 6.0.1

@lauron What is the target platform?
Can you copy/paste the complete error message?
