Rather than hijack the other thread I thought I would make a new one.

the  sparkfun BME280 library (very new library) fails to compile using VMicro and VS but is fine with the Arduino IDE.

https://github.com/sparkfun/SparkFun_BME280_Arduino_Library

I2C_ReadAllData.ino  (in the examples) is spitting out this compile error.

FYI I renamed the files ... from I2C_ReadAllData to SparkFunBME280 but it's the same as below with the original filenames.

I understand from the other thread that there is some kind of problem with the Arduino IDE ?

Is this correct or is it VMicro ?

Would love a solution in either case. 

Cheers,
