fyi. this compile error is on a mac os x. it works fine from my windows 7 PC.

Hi, I was super happy to find your library for the TH02. I just got a few of the sensors and I’m testing them right now. However, I do get a compile error indicating something going wrong with the TH02 lib.. but I’m not sure. Do you see anything out of the ordinary here…? Other I2C sensors I have works fine using the Wire lib. Grateful for all you work and hoping to be able to use it!

Here is a verbose output from the compiler, compiling the example from your library, the error is in bold at the bottom:
