opencv3: fix Python module build for Python 3.x

2018-04-08T14:52:09+00:00

When the OpenCV3 Python support is enabled with Python 3.x, it builds properly, and the resulting .so file is built for the target architecture, but its name is wrong: output/target/usr/lib/python3.6/site-packages/cv2.cpython-36m-x86_64-linux-gnu.so This prevents Python 3.x from importing the module: >>> import cv2 Traceback (most recent call last): File "", line 1, in ModuleNotFoundError: No module named 'cv2' In order to fix this, we simply need to pass PKG_PYTHON_DISTUTILS_ENV in the environment. The Python module then gets named: output/target/usr/lib/python3.6/site-packages/cv2.cpython-36m-arm-linux-gnueabi.so And can be imported properly: >>> import cv2 >>> This solution was suggested by Arnout Vandecappelle in https://stackoverflow.com/questions/49059035/buildroot-opencv3-python-package-builds-for-the-wrong-target. With Python 2.x, the module is named just cv2.so so this problem isn't visible. However, for consistency, we also pass PKG_PYTHON_DISTUTILS_ENV when building against Python 2.x, by putting the OPENCV3_CONF_ENV assignment inside the BR2_PACKAGE_OPENCV3_LIB_PYTHON condition, but outside the BR2_PACKAGE_PYTHON3/BR2_PACKAGE_PYTHON condition.

package/*/Config.in: fix help text check-package warnings

2017-12-18T08:22:54+00:00

This commit fixes the warnings reported by check-package on the help text of all package Config.in files, related to the formatting of the help text: should start with a tab, then 2 spaces, then at most 62 characters. The vast majority of warnings fixed were caused by too long lines. A few warnings were related to spaces being used instead of a tab to indent the help text. Signed-off-by: Thomas Petazzoni

opencv3: enable pthreads parallel for loops

2017-10-12T20:51:24+00:00

The WITH_PTHREADS_PF option was errantly categorized as a Windows only option. WITH_PTHREADS_PF actually enables a parallelization framework that utilizes pthreads to optimize some inner for loops of different OpenCV operations. This optimization is available on any platform that has pthreads. Signed-off-by: bradford barr Signed-off-by: Thomas Petazzoni

package/opencv3: bump version to 3.3.0

Globally replace $(HOST_DIR)/usr/bin with $(HOST_DIR)/bin

2017-07-05T13:19:29+00:00

Since things are no longer installed in $(HOST_DIR)/usr, the callers should also not refer to it. This is a mechanical change with git grep -l '$(HOST_DIR)/usr/bin' | xargs sed -i 's%$(HOST_DIR)/usr/bin%$(HOST_DIR)/bin%g' Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

package/opencv3: disable explicitly lapack support

2017-05-14T19:57:31+00:00

lapack support is enabled by default but the opencv3.mk doesn't handle this dependency yet. Fixes: http://autobuild.buildroot.net/results/c8a/c8a25af38c405594722b44aef34e5e4c549639db Signed-off-by: Romain Naour Cc: Samuel Martin Signed-off-by: Thomas Petazzoni

package/opencv3: regenerate patch without renames

2017-05-12T09:48:00+00:00

Patch using renames are not properly handled by patch < 2.7, which some users (including autobuilder instances) might be using. Such renames are silently ignored by old patch versions, caused strange build failures due to the missed renames. This patch fixes this by regenerating the patch without renames.

2017-05-07T20:09:17+00:00

An autobuilder exception has been added to avoid testing qt gui module with the CodeSourcery NiosII toolchain. This allow to remove the BR2_TOOLCHAIN_HAS_BINUTILS_BUG_19405 symbol.
