Can anyone help me in this, I want to build nix v0.15.0 on riscv64 platform.

@fricklerhandwerk I think this should be moved to nixpkgs

This seems like an issue with the nix Rust crate (https://crates.io/crates/nix) and not the Nix package manager. Please file your issue with them instead.

Hi all,

can anyone suggest me how to add local patches in cargo.

when i was looking inside source code,I found in one file linux.rs is not having riscv support, manually i added riscv in linux.rs but its failing.

now i want to apply patch in cargo, i have no any idea how to add patch in cargo.

i created patch by using diff -Naur a b > riscv.patch

riscv.patch-

--- a/linux.rs
+++ b/linux.rs
@@ -33,6 +33,8 @@
           target_arch = "arm",
           target_arch = "s390x",
           target_arch = "x86_64",
+          target_arch = "riscv32",
+          target_arch = "riscv64",
           target_arch = "aarch64"))]
 mod consts {
     #[doc(hidden)]

i added riscv line in linux.rs file.

// "Generic" ioctl protocol
#[cfg(any(
    target_arch = "x86",
    target_arch = "arm",
    target_arch = "s390x",

    target_arch = "aarch64",
    target_arch = "riscv32",
    target_arch = "riscv64"
))]

with the help of Cargo.toml file we can apply patches, but i want to know how to add,.

Can anyone help me in this.

Once more, your issue appears to have nothing to do with the Nix package manager (this repo), and instead is a problem with the nix Rust crate, which provides Rust-y bindings to "various *nix system functions".

Please file your issue with them.
