Adding Python package to Buildroot

danielswift · 12-15-2017, 12:33 PM

Hi there,

I am running an embedded system on Buildroot. I want to run a Python application on it which requires the PyDrive module.

I tried following this tutorial: https://github.com/maximeh/buildroot...ges-python.txt

and created a make and configuration file for PyDrive but PyDrive does not show up in my target packages. Does anyone know how to do this correctly?

Thanks,

D

I don't know this buildroot toolchain, but probably pip will work for you, so you can pip install PyDrive.

Unfortunately, my distribution does not have pip installed.

Thanks anyways for your help.

FYI, I don't need help installing pyDrive specifically but any python package into buildroot using menuconfig.

You can run pip install on your linux box, not on your embedded device. There are 2 cases - if it compiles something (most probably an so) you will need to recompile it for your embedded system. If not, you only need to pack the result and copy onto your device (but you may need to take care about dependencies too).

Hi there,

Sorry I am new to the Linux enviorment. How would I accomplish the cross compilation?

Thanks

pan64 · 12-18-2017, 03:19 PM

I think buildroot is used to do that

danielswift · 12-18-2017, 03:21 PM

I am sorry pan64. Could you clarify. I'm not sure if its me or that sentence did not make sense to me.

pan64 · 12-18-2017, 03:24 PM

it was your first sentence:

Quote:

I am running an embedded system on Buildroot.

If it was this: https://buildroot.org/, you can use it to compile additional packages too. But probably I have misunderstood.

Thanks pan64. I was wondering if you knew of any tutorial that taught me to do this or if you knew yourself. I am new to Linux, buildroot .etc and do not know how to cross compile the python package I would like to include.

pan64 · 12-19-2017, 04:17 AM

I played a bit with it, and it looks like you will need the following packages (they required by PyDrive):

Quote:

pip install PyDrive
.....
Successfully installed PyDrive PyYAML google-api-python-client oauth2client six uritemplate httplib2 pyasn1 rsa pyasn1-modules

The next question is: which packages are already available at you, because PyDrive itself does not require crosscompilation.

PyDrive is not a regular deb package, but a pip package, so you cannot put it directly into your system.
pip is available as a regular package, probably you will find it as python-pip

Hi,

I cannot find python-pip in menuconfig for buildroot.

Does this mean I cannot use PyDrive?

Thanks

what OS (distro) do you use at all?

danielswift · 12-19-2017, 08:51 AM

Linux buildroot 4.1.15 #3 SMP PREEMPT Thu Dec 7 16:50:14 EST 2017 armv7l GNU/Linux

pan64 · 12-19-2017, 09:02 AM

I think this is the target os, not the one where you run your build. isn't it?
