When you "select" an option, you must replicate the "depends on" of
that option into the selecting option. In this case, python-numpy has
the following depends on:
# Numpy has some CPU specific code
depends on BR2_aarch64 || BR2_arm || BR2_armeb || BR2_i386 \
|| BR2_mips || BR2_mipsel || BR2_powerpc || BR2_powerpc64 \
|| BR2_sh || BR2_x86_64
So you should replicate that into gnuradio/Config.in. However, since
this is horrible, here is what we do in such cases:
* Introduce a hidden BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS that
encodes this dependency.
* And then use this option in python-numpy/Config.in and
gnuradio/Config.in.
You can grep for ARCH_SUPPORTS in Buildroot to see other examples.
Thanks!
Thomas
