[yocto] Strange behavior with python recipe

[Shantanoo Desai]

Hello all, 

 

I am working with the following:

 

.       Hardware: Phytec-imx6-Mira Development board

.       Branch: krogoth

.       Bitbake Version: 1.30

.       Workflow tool: devtool

.       Build Env: Debian 9.4 server

 

I want to use the pynmea2 and influxdb-python modules on the embedded board
for application development. I added them using devtool and the recipes were
created accordingly.

I added the necessary RDEPENDS to the recipes and structured them to the
meta-python layer i.e. pynmea2.inc and pynmea2_1.7.1.bb (similar for
influxdb-python)

 

My application needs to be with python3 hence in the recipes I added `inhert
setuptools3 pypi` so that it builds for python3. I added these recipes in my
`local.conf` file.

 

Strangely, there is no `datetime` module available in the python3 shell when
I import these modules on the hardware. This same `datetime` module is
however available on python2 shell.

 

I explicitly added the `python3-datetime` in the `local.conf` file but still
the module is unavailable on hardware.

 

Links to necessary files and query:

I am not sure why isn't this python3-datetime module available on board even
though I have explicitly mentioned it in the RDEPENDS and
IMAGE_INSTALL_append ?

 

Any help would be appreciated. (First time poster in the mailing-list but
willing to learn the right etiquettes for asking queries here!)

 

Regards,

Shan
