Raspbian Stretch and Cross Toolchain for Linux and Mac OS

Raspbian Stretch is out for Raspberry Pi. I needed a cross toolchain with the same exact version used to build the system so I built my own. As I had my script ready, I also tried to build one for Mac OS and it seems to work for the moment. I tested these cross toolchains for my projects and seemed to be able to build everything that I tried: Qt libs, apps, omxplayer, ffmpeg etc...

Download Linux x64 cross toolchain GCC 6.3.0 for Stretch here.
Download Mac OS cross toolchain GCC 6.3.0 for Stretch here.

NOTE: The Mac OS version requires some packages to be installed from macports.
NOTE: The toolchain is built to crossbuild for armv7-a. I could also build for armv8 but not sure if it also works for armv6.

Have fun! Bye! ;-)

    Good job!!!
    I hope next POT version with LGPL license....
    Your implementation based on omxplayer is better than oficial Qt gstreamer-omx LGPL plugin

      I think you can use it with closed source anyway if that is what you need. You can't distribute, but you can use it.

    Hello Luca, great job.

    I have a simple question:
    Why are you building your own cross-compiler?
    a prebuilded linaro cros-compiler can be a good choice?

      And g++-arm-linux-gnueabihf debian cross compiler not is a good choice too?
      apt install g++-arm-linux-gnueabihf

      It depends on how it was configured. 4.9.4 was ok for Jessie, don't know about this one.

      I tested the one from Ubuntu once but I could not build Qt. It is probably built with a different setup. No idea about the specific one you refer to. I prefer to configure one properly myself and avoid weird errors during complex builds that are difficult to track down.

    Do you possibly have a link that is easily used with f.i. wget ?

    I'm trying to use this for compiling for a R Pi Zero (ARMv6), but I get a segfault trying to run even the simplest hello-world prog... :(

      Sorry, never tried to build for armv6 with this toolchain.
