you're better off contacting her via the github, this comments section is 90% "it's out of date" from people who didn't scroll down before posting

can you please add 'riscv64' to the arch's? I have tested this on a VisionFive 2 and it works fine.

arch=('i686' 'pentium4' 'x86_64' 'arm' 'armv7h' 'armv6h' 'aarch64' 'riscv64')

If the .cargo/config setting is preferred

Amazing

@Morganamilo Please add export RUSTUP_TOOLCHAIN=stable in the prepare and build sections because if you don't have any toolchain configured by default you get the following error:

error: rustup could not choose a version of cargo to run, because one wasn't specified explicitly, and no default is configured.
help: run 'rustup default stable' to download the latest stable release of Rust and set it as your default toolchain.

The line should be added before the charge fetch:

prepare() {
  cd "$pkgname-$pkgver"
  export RUSTUP_TOOLCHAIN=stable
  cargo fetch --locked --target "$(rustc -vV | sed -n 's|host: ||p')"
}

And before cargo build:

export RUSTUP_TOOLCHAIN=stable
cargo build --frozen --features...

Thanks!

If you're getting errors like

error: failed to select a version for the requirement env_logger = "^0.10.1" candidate versions found which didn't match: 0.9.3, 0.9.2, 0.9.1, ... location searched: crates.io index

then it might mean that you use rustup to provide cargo, and need to manually update the toolchain to use the latest cargo index. Run

rustup update

cargo fetch --locked --target "$CARCH-unknown-linux-gnu"

breaks on armv7h with error: Error loading target specification: Could not find specification for target "armv7h-unknown-linux-gnu"

cargo fetch --locked --target "$(rustc -vV | sed -n 's|host: ||p')"

like in https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=cfddns

I think pkg-config[build] and sudo[optional; for building AUR packages] should be dependencies.

@siavoshkc I had the same error. I have rustup (ie the whole rust toolchain, not just rust) installed on my system and I resolved this issue by running 'rustup update' then doing 'paru -S paru'. Hopefully this is of help to you.

Get this error while installing:

error[E0658]: use of unstable library feature 'once_cell'
