I am trying to add libiio to my Yocto image, and I'm using the libiio recipe from meta-oe. The library seems to be added, however I can't seem to enable the python bindings.
In that recipe, there are the lines
PACKAGECONFIG ??= " \
usb_backend network_backend serial_backend xml_backend \
${@bb.utils.contains('DISTRO_FEATURES', 'zeroconf', 'dnssd', '', d)} \
"
# ...
PACKAGECONFIG[libiio-python3] = "-DPYTHON_BINDINGS=ON,-DPYTHON_BINDINGS=OFF"
I have a bbappend file libiio_%.bbappend with:
PACKAGECONFIG:append = " libiio-python3"
Running bitbake -e libiio | grep PACKAGECONFIG returns.
PACKAGECONFIG=" usb_backend network_backend serial_backend xml_backend dnssd libiio-python3"
In the log.do_confiure file, there are these lines:
-- Found Python: /home/<name>/yocto/poky/build/tmp/work/cortexa9t2hf-neon-poky-linux-gnueabi/libiio/0.23-r0/recipe-sysroot-native/usr/bin/python3-native/python3 (found version "3.10.9") found components: Interpreter

-- Found Python: Building bindings
And in the log.do_install file, there are these lines:

But the python bindings are not part of the built image.
How do I enable a feature using PACKAGECONFIG?
Did you install libiio-python3? The recipe puts the python bindings into a separate package.
