@MichaelChou, that depends on the amount of obligations tied to this title ;). But since I'm likely going to use this PKGBUILD (as a dependency of ROS) in the future, I guess this might be useful. Feel free to contact me by mail (see my AUR profile) :).

BTW, OpenCV has fixed this in their 3.4 branch (https://github.com/opencv/opencv/pull/17983), the next release should be fine again.

@Windfisch, thanks for your excellent work!

I've updated the PKGBUILD to include your patch. Also updated OpenCV to v3.4.11, cleaned up deprecated workarounds which are not needed anymore.

@Windfisch, would you like me to add you in the co-maintainer list of this package? No pressure though.

Windfisch commented on 2020-07-29 18:23

Due to a recent libjasper update, the build of this package fails.

For details, please refer to the upstream issue https://github.com/opencv/opencv/issues/17984

Until the patch has been accepted into OpenCV 3, here's a workaround by adding the patch to the PKGBUILD: https://github.com/Windfisch/pkgbuild-opencv3-opt

@MichaelChou, could you please update the PKGBUILD accordingly :)?

fixed by a workaround, until upstream (tbb) fixed

I had the same stdlib.h error, @crnchbng's solution worked for me.

crnchbng commented on 2019-10-24 17:44

I had to add the 2 following lines

-DCMAKE_NO_SYSTEM_FROM_IMPORTED=ON \
-DENABLE_PRECOMPILED_HEADERS=OFF \

I can confirm that the package compiled after adding

-DCMAKE_NO_SYSTEM_FROM_IMPORTED=ON

That was the exact same problem I was facing. I reverted my change and the problem appeared again.

I will include my patch here, so that if anyone wants to try it they can reproduce my exact change

It might very well be, that I just got lucky with the include order produced by this, as hinted at in the previous comment.

@crnchbng's fix works

I have also had issues building this package. For me the error occurred at:

stdlib.h exists in this directory, so I am unsure why this causes the compilation to terminate, however the fix submitted by @dreuter does not seem to help.
