If the pkgbuild insists on using make, then it also needs the cmake argument -G"Unix Makefiles". I otherwise use ninja for all cmake builds, so this pkgbuild does not work out-of-the-box if one has ninja installed and has CMAKE_GENERATOR=Ninja environment variable.

@haagch: it build now for me too, I'm surpised ;-)

99% I tried clean-build it before(also tried using opencv2-opt, older branch), but I'm updating my archlinux from testing daily ;-)

@pix3l sorry about forgetting about your comment. Unfortunately I can't reproduce that, it builds fine here. If you have a former src/ directory, try nuking that (or makepkg -C).

@haagch: it won't build for me :-(

Updated with patch for opencv4 since opencv2-opt doesn't build anymore.

It compiles but I have not tested running it. If you want to contribute with OpenCV4 knowledge, please contribute in the upstream issue https://github.com/OSVR/OSVR-Core/issues/596 or just make a PR to tis branch https://github.com/ChristophHaag/OSVR-Core/tree/opencv4

Hmm the opencv2-opt package doesn't actually have that videoio library, so to compile it you have to install the repo opencv package too.

I wonder if this can break something...

Hello, I get the following error when trying to build the package:

[ 96%] Linking CXX shared module ../../lib/osvr-plugins-0/org_osvr_unifiedvideoinertial.so

/usr/bin/ld: cannot find -lopencv_videoio
