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 <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, 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
<pkg>_KEEP_PY_FILES mechanism, to ensure the important config*.py
files are kept.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
