Created attachment 706488 [details] opencv-4.5.0.log The ebuild fails to (re)install with "rm: cannot remove 'modules/python3': No such file or directory". Last time it was installed successfully was in Jan 2021, but it now needs to be rebuilt due to dependencies (protobuf) and fails as per attached log.

I have same problem with 4.5.0 and with 4.5.1

Same problem. Not only with opencv. scipy, pandas also fails.
(In reply to Alexander Koryushkin from comment #8) > Same problem. Not only with opencv. > scipy, pandas also fails. Please verify this with the latest ~arch Boost and boost-build.
This bug came back to bite me, I needed to add the following to the opencv ebuild: python_module_compile() { [...] # Regenerate cache file. Can't use rebuild_cache as it won't # have the Gentoo specific options. rm CMakeCache.txt || die "rm failed" cmake_src_configure cmake_src_compile cmake_src_install + # https://bugs.gentoo.org/788712 + mkdir -p modules/python3 # Remove compiled binary so new version compiles # Avoid conflicts with new module builds as build system doesn't # really support it. rm -r modules/python3 || die "rm failed" python_optimize "${ED}"/$(python_get_sitedir) }
Complete ebuild is here: https://github.com/NTULINUX/ntu_overlay/blob/main/media-libs/opencv/opencv-4.6.0-r4.ebuild
Created attachment 850366 [details] Fix rm failure (full ebuild)
This bug still isn't fixed. OpenCV 4.7.0 still fails without mkdir -p python3/modules before rm -r modules/python3.
Meant to say mkdir -p modules/python3 earlier.
