Compilation Error on Arduino-Esp32

[enoch-prince]

Compilation of the I2C example for the ESP-WROOM-32 Dev Board using the Arduino 2.3.2 IDE, failed with exit status 1 and the message:

cc1plus.exe: some warnings being treated as errors

Details of the error log is below:

Please download the library directly from GitHub, it looks like you're on a very old version.

Versions used

• Units Conversion: V5.0.0
• Eigen: V3.0.2
• Invensense-IMU: V5.6.0

Yet still get the same compile errors as described above.

Furthermore, the following files in the Units library also produce the same errors:

convdensity.cpp
convangacc.cpp
convacc.cpp
convang.cpp
convangvel.cpp

[flybrianfly]

The current version of the InvenSense IMU library (v6.0.3) does not need Eigen or Units.

Great 👍🏽! v6.0.3 fixed the compilation errors.
