Can not build with clang18

[Schievel1]

Hi,

I have some trouble building this on one system, the weird thing is it works fine on another system.
I can't figure out why that happens, it can not find the bindings below.

     Running `rustc --crate-name skia_bindings --edition=2021 /var/tmp/portage/app-editors/neovide-0.12.2/work/cargo_home/gentoo/skia-bindings-0.68.0/src/lib.rs --error-format=json --json=diagnostic-rendered-ansi,artifacts,future-incompat --crate-type lib --emit=dep-info,metadata,link -C opt-level=3 -C linker-plugin-lto --cfg 'feature="binary-cache"' --cfg 'feature="embed-icudtl"' --cfg 'feature="flate2"' --cfg 'feature="gl"' --cfg 'feature="lazy_static"' --cfg 'feature="tar"' --cfg 'feature="textlayout"' --cfg 'feature="ureq"' -C metadata=490906c54de2ec60 -C extra-filename=-490906c54de2ec60 --out-dir /var/tmp/portage/app-editors/neovide-0.12.2/work/neovide-0.12.2/target/release/deps -L dependency=/var/tmp/portage/app-editors/neovide-0.12.2/work/neovide-0.12.2/target/release/deps --extern lazy_static=/var/tmp/portage/app-editors/neovide-0.12.2/work/neovide-0.12.2/target/release/deps/liblazy_static-b190eea2c81aa18e.rmeta --cap-lints allow -L /var/tmp/portage/app-editors/neovide-0.12.2/work/neovide-0.12.2/target/release/build/skia-bindings-e1350025a1d273d6/out/skia -l static=skparagraph -l static=skshaper -l static=skunicode -l static=skia -l static=skia-bindings -l stdc++ -l fontconfig -l freetype -l png16 -l z -l icudata -l icui18n -l icuio -l icutest -l icutu -l icuuc -l harfbuzz -l expat -l jpeg`

From a first glance, the feature set does not match the bindings. Is this a full build or are binaries downloaded? And did you try to delete the target/ directory before a rebuild?

[Schievel1]

I checked the gn_args across both machines and they are the same. So I assume it's not creating the bindings according to the features on one machine.

Build is full, I let the package manager download the source from your repo beforehand because of sandboxing during build and then set SKIA_SOURCE_DIR accordingly.

Not only target but the whole source directory of skia and skia_rust is deleted between builds.

With package manager I don't mean cargo but a distro's package manager. Emerge in fact. I put the build script here

here is the bug with the full build log https://bugs.gentoo.org/928647

[dbger]

I have same trouble, failed to build it with the lastest clang(18.1.3), but the clang(17.0.6) is okey.

Yes, thats the reason! Thanks for clearing that up, I wasn't sure what the difference between those two machines is where one works and one does not.
The one that works has clang17, the one where it does not has clang18.
