Arch Linux User Repository

Hello this package needs some updates:

1. License is not SDPX compliant; needs to be changed to MPL-2.0
2. cargo-nightly instead of cargo. Servo has a rust-toolchain.toml file, which specifies a specific version of rust. To use that, cargo-nightly will install rustup. In addition, the export RUSTUP_TOOLCHAIN=stable needs to be commented out for rust-toolchain.toml to be used.
3. Disable LTO. Currently, building with LTO enabled results in an error. I tried using lld, export CFLAGS+=" -ffat-lto-objects, and export CXXFLAGS+=" -ffat-lto-objects"—none of them worked.
4. Autoconf2.13 is no longer needed.

Here is a patch file for the PKGBUILD:

confirm crown -vV error

I guess we need setup proper environment ...

Clean chroot. Same crown -vV error. Unfortunately, I don't know how to fix.

@xiota Happy to accept contributions. Upstream has been messing around with the build system(s) and keep adding and removing stuff. If you have patches that work to make this build at any given point feel free to post them here or ever better PR them here.

Clean chroot. Fails to build.

@mble It looks like the Arch [community] package for python-blessings is newer than this build demands. Probably the thing to do is patch the servo sources to be more accepting of other versions, then if it doesn't build with 1.7.x submit a patch to servo upstream to fix it. I'm happy to accept such a patch (either in comments with git format-patch or as a PR on this repository) but I'm unlikely to have time to hack around on this build any time too soon. Also either way this should be reported upstream.
