![Romain Naour](/assets/img/avatar_default.png)
Since version 3.4.1 [1], opencv disable pkg-config while cross-compiling to
avoid host headers/libraries poisoning.
Due to this, opencv fail to detect ffmpeg, gstreamer and gtk dependencies
even if the corresponding support is requested by
BR2_PACKAGE_OPENCV3_WITH_{FFMPEG,GSTREAMER,GTK2,GTK3}.
Maybe other dependencies are affected by this issue...
While configuring opencv we can notice the following messages:
"-- OpenCV disables pkg-config to avoid using of host libraries. Consider using PKG_CONFIG_LIBDIR to specify target SYSROOT"
"-- Can't find ffmpeg - 'pkg-config' utility is missing"
As the result ffmpeg and gstreamer are not enabled:
-- Video I/O:
-- FFMPEG: NO
-- avcodec: NO
-- avformat: NO
-- avutil: NO
-- swscale: NO
-- avresample: NO
-- GStreamer: NO
-- libv4l/libv4l2: NO
-- v4l/v4l2: linux/videodev2.h
We can fixes this by adding a new option OPENCV_ENABLE_PKG_CONFIG=ON
-- Video I/O:
-- FFMPEG: YES
-- avcodec: YES (ver 58.35.100)
-- avformat: YES (ver 58.20.100)
-- avutil: YES (ver 56.22.100)
-- swscale: YES (ver 5.3.100)
-- avresample: YES (ver 4.0.0)
-- GStreamer:
-- base: YES (ver 1.16.0)
-- video: YES (ver 1.16.0)
-- app: YES (ver 1.16.0)
-- riff: YES (ver 1.16.0)
-- pbutils: YES (ver 1.16.0)
-- libv4l/libv4l2: NO
-- v4l/v4l2: linux/videodev2.h
Add host-pkgconf in the dependencies.
If there is a path poisoning issue, it will be detected by the toolchain
paranoid wrapper.
