RaspberryPi: undefined reference to `i2c_smbus_read*' functions in C userspace

Asked 2021-Dec-06 at 12:52

I agree you don't need extern "C"in a C program. Check your headers and see if your header defines the function as inline or not. If it only declares it, you need to find out which library is the function defined in and link the library in your program.

Edit: I see you already updated the question. In this case you need to link the i2c library similar to what they do here. Just add a parameter to your gcc command: -li2c.

Did anyone of you try to add it to the system generated by "Yocto" and maybe have suggestions about how to start and how to add it? Target is to use these two libraries in userspace app.
