Problem building Particle Argon with Bylnk library - undefined reference to BlynkWidgetWriteInternalPinDBG

Issues and Errors
1

I’m trying to build a project for a Particle Argon board using the library I downloaded here:

I’m using 5.1.0 of the Particle OS.

I’m getting the following error when I build:

Creating c:/Users/jayk/work/particle/monitor2/monitor2/target/5.1.0/argon/platform_user_ram.ld …

I’m including blynk.h in my code and I have a #define BLYNK_PRINT Serial before that.

My code used to work with an older version of the Blynk lib.

Any thoughts?

If you open the file:
c:/Users/jayk/work/particle/monitor2/monitor2/lib/blynk/src/Blynk/BlynkProtocolDefs.h

does it contain 122 lines, ending with…

#define BLYNK_INT_RTC  BLYNK_STR_32('r','t','c',0)
#define BLYNK_INT_UTC  BLYNK_STR_32('u','t','c',0)
#define BLYNK_INT_OTA  BLYNK_STR_32('o','t','a',0)
#define BLYNK_INT_VFS  BLYNK_STR_32('v','f','s',0)
#define BLYNK_INT_DBG  BLYNK_STR_32('d','b','g',0)
#define BLYNK_INT_ACON BLYNK_STR_32('a','c','o','n')
#define BLYNK_INT_ADIS BLYNK_STR_32('a','d','i','s')
#define BLYNK_INT_META BLYNK_STR_32('m','e','t','a')

#endif

Yes it does. But I can’t see where those BlynkWidgetWriteInternal??? functions are defined…
