compiling bme280 from yanbe

[vibnwis]

Hi there,
I am wanting to try the source from repo, https://github.com/yanbe/bme280-esp-idf-i2c.git. However, when I built it, it could not find bme280.h as stated as #include "bme280.h" in the main.c. Out of no choice, I found a copy of bme280.h from https://github.com/whitecatboard/Lua-RTOS-ESP32.git. It is becoming very complicated beyond my capability. Can someone help please? I gave it a go, by copying bme280.h, bme280.c and sensor.c, sensor.h to esp_idf/driver/ and its include folders. However, I experienced the following errors. Any comments are welcome.

After revisiting the yanbe repo, I found out the bme280.h and bme280.c have rerouted to Bocsh repo. Having clone from the site, I managed to remove all bme280 related errors. However, I faced the following errors.

Appreciate any comments ?

Further investigation I could resolve the error messages by adding

return 0;

at the end of the related functions.

However, if someone have better solution, I would like to hear it.

Thanks

That's a fine solution. Or, you could experiment with with changes to the compiler command, probably in a makefile or config file, to ignore this error.
