The following extra patch is necessary to allow building the highgui module:

＠jerry73204 hey, could you help me with maintain this pkg?

The PKGBUILD renames share/OpenCV to share/opencv. It causes the cmake config files unusable (See this issue).

In this issue, cmake script assumes /opt/opencv2/share/OpenCV/java/libopencv_java2413.so, which parent directory is gone.

Please include this patch in order to fix it.

now It compiles.

Hi, I've disowned package, because I don't have enough time to take care of it.

If you don't need ffmpeg dependencies you can disable it by adding in your CMAKE this option: -D WITH_FFMPEG=OFF

Any workaround ? How can I try using ffmpeg2.8 ?

Try using ffmpeg2.8.

The same problem is for opencv2

Same here, built fails at 10%
