Build GPIO_Lib_C fail

[Charlie 0]

For example, the C code from : https://github.com/TinkerBoard/gpio_lib_c

but cannot build it on gpio_lib_c, my usage:

sudo ./build

the output is:

I do have the same problem. Did you find a solution? Is the Tinkerboard project dead? So many topics here do not have solutions/aswers.

hello @Charlie and @JulianR, 

here's the compiling sample code for your reference: Developer Guide · TinkerBoard/TinkerBoard Wiki · GitHub

have you executed the first step? ->Firstly, modify the /boot/config.txt file as following and then reboot to enable I2C1 and I2C4.

Hi @Charlie and @JulianR:

      The gpio_lib_c source path of TInker Board 2 locate /usr/local/share/gpio_lib_c_rk3399 in system.

We have prebuild and install the library in release image. And, you can include it directly

Did you have other requirements and need to rebuild the library?  

Thank a lot!

Yes it is working, I also used the libraray from "https://github.com/TinkerBoard/gpio_lib_c" instead of "/usr/local/share/gpio_lib_c_rk3399"
