先clone项目： git clone https://github.com/ReFirmLabs/binwalk.git 安装Rust编译环境： curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh source "$HOME/.cargo/env" 在binwalk目录下： carg

https://zer0ptr.github.io/2025/12/13/ubuntu-install-binwalk-lasted/

官方源较慢的可以使用阿里源：https://mirrors.aliyun.com/repo/rust/rustup-init.sh

[zer0ptr]

在编译binwalk时如果最后显示：

这个警告是因为 InternalExtractor 类型包含函数指针，而 Rust 编译器自动为枚举生成的 Eq、PartialEq、Ord、PartialOrd trait 实现会直接比较函数指针的地址，这在某些编译器优化下可能不可靠，我们可以尝试手动实现比较trait，在 src/extractors/common.rs 中，将自动派生改为手动实现：

[zer0ptr]

在第30-33行改成：

[zer0ptr]

/// Enum to define either an Internal or External extractor type
#[derive(Debug, Default, Clone, Eq, PartialEq, Ord, PartialOrd)] // ← 这里
pub enum ExtractorType {
External(String),
Internal(InternalExtractor),
#[default]
None,
}

[zer0ptr]

第二个地方（第40-41行），改成
/// Describes extractors, both external and internal
#[derive(Debug, Clone, Default, PartialEq, Eq)] // ← 去掉 PartialOrd, Ord
pub struct Extractor {

[zer0ptr]

请忽略上一条对编译时异常的评论，这是因为rust更新到了1.78以上版本编译器会检查这个问题，只需要在src/extractors/common.rs文件中把以下代码放到第一行即可（让编译器忽略这个问题）
#![allow(unpredictable_function_pointer_comparisons)]
