@chrisqq Hi, you can try uncommenting the line options=(!lto) in PKGBUILD to disable LTO.

This fails on cachyos on this error: lto1: fatal error: bytecode stream in file ‘dlib_build/libdlib.a’ generated with LTO version 12.0 instead of the expected 13.0 compilation terminated. lto-wrapper: fatal error: /usr/bin/c++ returned 1 exit status

Not really sure how I can fix this, any h elp appreciated.

The python-dlib package now requires cuda, is there any way to just install the package and not the entire pkgbase, without cuda? I'm on AMD.

hi, this package does not depend on boost, but has an optional make dependency on libwebp.

19.24.2 PKGBUILD

this version imporve the recognition speed, and can build under py3.11

Can conform the issue mentioned by @Misaka13514, this is not building anymore and failing its dependents packages from being installed.

19.24.1's PKGBUILD like that:

These changes may be useful to fix this package with Python 3.11
