我正在尝试在Slackware 4.1上编译opencv。但是我每次都遇到以下错误。

我查看了以下链接中的opencv要求
我需要ffmpeg或libav包，这是我在标准slackware 14.1包下找不到的。但我完全安装了gstreamer（gstreamer，gst-pluigns-base，以及好），我上面遇到的错误肯定与gstreamer有关。
答案 0 :(得分：10)
我通过安装var_dump(array_filter($medium['properties']['keywords']), $medium['properties']['keywords']);
解决了这个问题。在此之前，CMake检测到GStreamer版本0.10.36，之后是1.4.5。
答案 1 :(得分：3)
我将WITH_GSTREAMER_0_10设置为ON
后，它对我有用答案 2 :(得分：1)
我正在使用Ubuntu 12.04，但得到了同样的错误。 使用 -D WITH_GSTREAMER = OFF 参数可以避免这种情况。 建议here和here。
然后here他们建议更新gstreamer，但这并没有为我解决。 我仍然希望通过全新安装来验证这一点。
答案 3 :(得分：0)
如果有人仍然有问题， 尝试使用所有软件包正确安装gstreamer1.0
Fedora OS的示例：
dnf install gstreamer1-devel gstreamer1-plugins-base-tools
gstreamer1-devel-docs gstreamer1-plugins-base-devel
gstreamer1-plugins-base-devel-docs
gstreamer1-plugins-good gstreamer1-plugins-good-extras
gstreamer1-plugins-ugly gstreamer1-plugins-ugly-devel-docs
gstreamer1-plugins-bad-free gstreamer1-plugins-bad-free-devel
gstreamer1-plugins-bad-free-extras
