Deploy wiringpi libraries while cross compiling



  • Has anyone had any luck deploying wiringpi or similar libaries during cross compiling to a rpi3?

    I've been doing some experimentation (successfully) with controlling the GPIO pins using direct register access by just defining a new "mmapGpio" class using modified code from here:
    http://www.hertaville.com/rpimmapgpio.html

    I am deploying this on a lightweight embedded linux image on rpi3 that does not have the wiringpi libraries installed. This approach is working fine, but where I am running into problems is when I try to incorporate additional features such as interrupts and integrating analog i/o cards. This is where I need to use the wiringpi or similar libraries.

    Do I need to build or find an embedded linux image that includes the wiringpi libraries. Or is there any other way to accomplish this or deploy the libraries during cross compile?

    Hi,

    Cross-compilation and deployment are two different things.

    The best thing is usually get the library with the distribution/image whatever you use for your target as it’s ready to use.
