Set _build_cpu and _build_cuda to 1 and 0 to build or not build the CPU or CUDA version.

If options=(!lto) has no effect, please check if it's still enabled in /etc/makepkg.conf.

The options=(!lto) setting in a PKGBUILD always overrides the LTO switch for that particular build, regardless of what any makepkg.conf contains.

@petronny Please update the PKGBUILD as pointed out by Encrypt-Keeper.

Disabling LTO in /etc/makepkg.conf gets rid of the error. Thanks.

@ndoskrnl You seem to be mistaken, I'm not the maintainer, and it appears that this doesn't resolve the issue for some users.

I can confirm the issue with being unable to build due to the error generated with LTO version 12.0 instead of the expected 13.0 compilation terminated:

Uncommenting options=(!lto) in the PKGBUILD has no effect. Still fails with the same error.

Editing /etc/makepkg.conf and replacing OPTIONS=(strip docs !libtool !staticlibs emptydirs zipman purge debug lto) with OPTIONS=(strip docs !libtool !staticlibs emptydirs zipman purge !debug !lto)

Allowed me to successfully build the package.

Disabling LTO in /etc/makepkg.conf can resolve the issue of generated with LTO version 12.0 instead of the expected 13.0 compilation terminated:

- OPTIONS=(strip docs !libtool !staticlibs emptydirs zipman purge debug lto)
+ OPTIONS=(strip docs !libtool !staticlibs emptydirs zipman purge debug !lto)

I am having the same issue with the LTO version. Uncommenting ##options=(!lto) does not make any difference. The package build still fails and gives the same error.

Has anyone found a way around this yet?

@MarsSeed I found the cause of issue by compare my system's '/etc/makepkg.conf' with the one in clean chroot. It shows that new version of pacman (as of 'core/pacman 6.0.2-9' now) makes option link time optimization enabled by default:

Since the makedep 'cuda' is still using gcc-12 which will generate 'dlib_generated_cuda_dlib.cu.o' and 'dlib_generated_cusolver_dlibapi.cu.o':

So new installed systems will built python-dlib[-cuda] into fails at all due to different LTO version.

Therefore I recommend the maintainer @Eeems to uncomment the '##options=(!lto)' in file PKGBUILD default.

In case anybody is wondering, a fresh build using archlinux:latest with base-devel, and the required packages works with no issue. So something appears to be wrong with MarsSeed's system. If anybody else is having the same error, it would be helpful if you were to leave a comment as such, and if the solution provided here works: https://aur.archlinux.org/pkgbase/python-dlib#comment-945557
