Bug ID: 12171
Summary: Python-opencv needs config.py and config-3.7.py to
run. Only the *.pyc is not enough.
Product: buildroot
Version: 2019.08
Hardware: Other
OS: Linux
Status: NEW
Severity: trivial
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: ivan.nazarenko at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
When importing cv2 in python 3.7, the program stops with:
File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 89, in <module> File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 58, in bootstrap File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 56, inload_first_config
ImportError: OpenCV loader: missing configuration file: ['config.py']. Check OpenCV installation.
Since buildroot removed all *.py, leaving the corresponding *.pyc, the above config.py file is not in target. But these two files are currently needed uncompiled for "import cv2".
We can of course specify BR2_PACKAGE_PYTHON3_PY_PYC=y, but this would make all *.py in target, which is sort of a waste.

--- Comment #1 from Fabrice Fontaine <[email protected]> --- I sent a patch to "fix" this issue: https://patchwork.ozlabs.org/patch/1158640.
This patch adds a !BR2_PACKAGE_PYTHON_PYC_ONLY dependency on opencv3's python option.
