From d07c315f0c24903e03169c939b050618a9c3ba8b Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Fri, 29 Nov 2019 20:07:06 +0100 Subject: [PATCH] package/opencv3: ensure the python module works when BR2_PACKAGE_PYTHON{, 3}_PYC_ONLY=y The OpenCV Python module does a fairly strange thing to read a few configuration details: it uses Python's execfile() to execute two .py files and access a few variables. However, execfile() only works with .py files and not .pyc files. When BR2_PACKAGE_PYTHON{,3}_PYC_ONLY=y, the .py files are all removed, causing the OpenCV Python module to not work: File "usr/lib/python3.7/site-packages/cv2/__init__.py", line 89, in 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, in load_first_config ImportError: OpenCV loader: missing configuration file: ['config.py']. Check OpenCV installation. To fix this problem, this commit uses the newly introduced _KEEP_PY_FILES mechanism, to ensure the important config*.py files are kept.
