Can't install, compile errors

[fromeijn]

Hey guys,

I'm trying to install this package on a BeagleBone Black with a Kernel 4.14. tried to install it with pip, pip3 and with python(3) setup.py install giving the same results. I have a custom image generated with yocto. Any help would be really appreciated. If more information is needed, please tell me.

pip3 install Adafruit_BBIO

This library only officially supports the BeagleBoard.org Debian images.

On Debian, these packages are needed:

sudo apt-get install build-essential python-dev python-pip -y

Here is what is in build-essential:
https://packages.debian.org/stretch/build-essential

[pdp7]

@fromeijn I'd suggest adding Yocto/OpenEmbedded recipes for the software listed in:
https://packages.debian.org/stretch/build-essential
https://packages.debian.org/stretch/python-dev
https://packages.debian.org/stretch/python-pip

I don't have Yocto environment to test myself.

[fbertux]

I saw this error too. I think this is related to https://bugs.python.org/issue33012. @pdp7 did you test with gcc 8.2?

[pdp7]

@RobertCNelson Do you know if GCC 8.2 packaged for the BeagleBoard.org Debian image? Thanks.

[RobertCNelson]

@pdp7 grab the buster image, (buster ships 8.2.0 right now)

@fromeijn as quick and (really) dirty way to be able to install (and use) this lib, i removed "-Werror" from CFLAGS list in setup.py (manual installation).

[jlinford]

This is the same problem as #308

[pdp7]

I am going to close this in favor of tracking this problem under issue #308

I believe I have a fix in PR #321
