Hello,
I have been using Yocto for several years now and I really
appreciate all the hard work you all are putting into this
project!
I have up until now been able to find documentation or answers to
questions that cover my issues. But this time I have not been able
to find my way, maybe I am using the wrong search terms.
Some background,
Running on a custom embedded device, powered by a AM3552 soc,
currently running Dunfell.
I have a recipe that compiles a software using CMake. CMake in
turn uses a Python3 script in the build step to generate some
source files based on a CSV file. That script uses the
python3-pandas library.
In my recipe I include python3-pandas as a DEPENDS
# For some reason python3-pandas-native
does not pull in its dependencies, pytz and dateutil.
# The same is true for dateutil which depend on six
DEPENDS += "python3-pandas-native python3-pytz-native
python3-dateutil-native python3-six-native"
This works great for building the
firmware image file.
But in the generated SDK or Extensible
SDK the modules are not available.
$ which python3
/home/daad/cem-fw-dev_sdk_chc/sysroots/x86_64-pokysdk-linux/usr/bin/python3
$ python3
Python 3.8.2 (default, Feb 25 2020, 10:39:28)
[GCC 9.3.0] on linux
Type "help", "copyright", "credits" or "license" for more
information.
>>> import pandas
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'pandas'
>>>
I have also tried using the extensible
sdk but i get another error when trying devtool
devtool modify recipie fails with
python error: Exception:
ModuleNotFoundError: No module named '_sysconfigdata'
I am unsure how to continue, where should I look for the issue? I
am assuming that "depending" on a native python package would
cause it to be included in the SDK..? even thugh it is a python
dependency?
This has worked for other recipies (non-python) dependencies.
It "feels" like somehow the python3 "install" in the sdk is not
identical to the one that is used when building the images.
Best Regards
