  • Building a library . . .

    From RJH@3:770/3 to All on Sun Oct 16 18:47:22 2022
    I'm trying to build a thermal camera and I've got stuck at "building" from
    this guide https://github.com/pimoroni/mlx90640-library

    I'm not sure where I 'make all' etc - in usr/local it returns things like 'no target specified', and 'no rule'.

    It's using a Pi 3 and internal storage with the Pimoroni breakout garden from
    a fresh default OS image - very new to all of this so I'm not sure what's important hardware wise.

    Any pointers appreciated.

    Have you grabbed the source code into a folder and unzipped it? There's a makefile in the top level folder, There are other way such as checking it out using git

    You have to change directory to the location of the Makefile. The usual process is:

    $ git clone https://github.com/pimoroni/mlx90640-library.git
    Cloning into 'mlx90640-library'...
    remote: Enumerating objects: 640, done.
    remote: Counting objects: 100% (68/68), done.
    remote: Compressing objects: 100% (47/47), done.
    remote: Total 640 (delta 30), reused 34 (delta 16), pack-reused 572
    Receiving objects: 100% (640/640), 2.83 MiB | 630.00 KiB/s, done.
    Resolving deltas: 100% (351/351), done.

    $ cd mlx90640-library/

    $ make all
    g++ -DDEBUG -g -fPIC -I headers -shared -c -o functions/MLX90640_API.o functions/MLX90640_API.cpp

    That's it, all done! Many thanks - and to Andy - I think that was what you
    were driving at.

    Camera works. Now for the real fun . . .
