[Buildroot] [Question] - Buildroor 2021.02 - Can't find python-numpy in menuconfig (python 2.7)

Hi all,

I'm trying to build the numpy package for python2.7. Unfortunately I have to use python 2.7 before I'm able to upgrade. When I search "/" python-numpy in menuconfig, it tells me it's in "Target Packages -> Interpreter languages and scripting -> External Python Modules". But I can't find it on the list.

I tried adding it on my _defconfig as
BR2_PACKAGE_PYTHON_NUMPY=y
BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS=y
But that doesn't make a difference either.

I haven't spotted any typos.

What's the correct way to add numpy to python 2.7? Any help is appreciated.

Cheers,

Alberto

Note that Python 2.7 has been removed from the latest 2022.02 release.
Which version are you using?

There might be an unsatisfied dependency. The search results should show
you the list of BR2_PACKAGE_PYTHON_NUMPY dependencies, and whether they
are enabled. Specifically python-numpy needs glibc or musl C libraries.
In that case you should see this comment in the menu:

    *** python-numpy needs glibc or musl ***

Another options is that numphy does not support your target
platform. See the list of platforms under
BR2_PACKAGE_PYTHON_NUMPY_ARCH_SUPPORTS in
package/python-numpy/Config.in. In that case the menu comment does not
show.

Kconfig removes symbols with unsatisfied dependencies.

Hi Baruch, thanks for your help.

I figured it out. I was using v2020.11 and v2020.05, and that gave me all sorts of trouble. The combination that worked for me was:

  *   BR 2020.02
  *   BR2_TOOLCHAIN_BUILDROOT_GLIBC=y
  *   Kernel 5.4

Earlier versions did not allow me to use the kernel 5.4.

It took me a while to get all right, I had to do a few rebuilds from scratch, but it's all working now. Many thanks!

Cheers,

Alberto
