I had to install nlohmann-json, qt6-5compat, and verdict to fully compile. Version 4.9.0.

evorster, could you define "latest versions of java and the jdk"? I have 21.u35-8 for the openJDK, but it won't let me simultaneously install that for the JRE, so, I have no idea what you mean.

Edit: Figured it out, for anyone else with this issue, archlinux-java status, see which is the latest, then archlinux-java set (latest), so for example, mine was java-21-openjdk, so, archlinux-java set java-21-openjdk (needs to be run as root), and it built just fine.

To solve the dependency issues, each package needs to provide and conflict with it's own non-git version.

I got that error below sorted by installing the latest versions of java, and the jdk. The problem I am running into now is that a few of my installed packages depend on "opencv" and this package conflicts with opencv, but does not provide it.

Can we add: provides=('opencv') somewhere in the PKBUILD, please?

Hi there! This package almost builds, I get this error in the install phase:

I was having issues compiling and getting the following error:

/usr/include/absl/base/policy_checks.h:79:2: error: #error "C++ versions less than C++14 are not supported."
   79 | #error "C++ versions less than C++14 are not supported."
      |  ^~~~~

This appears to be related to this bug in opencv.

Adding the following to the _cmakeopts got it to compile:

-DCMAKE_CXX_STANDARD=17

Seems like opencv-python doesn't support ffmpeg 5.0 so can't compile on latest Arch

Thanks for the heads up m00nw4tch3r (and others) and also thanks for the patience!(!!) I've refactored the package quite a bit and decided to split it as well. Let me know if this causes any issues.

As always, I was able to build this package in a clean chroot before pushing the changes so if you're experiencing build issues please attempt that first before reporting. Thanks!

Looks like the lapack patch isn't needed anymore, and it causes the build to fail.

It seems the patch is not working
