货生成会导致依赖编译错误。

Question

我对生锈的项目有问题，我的lib.rs只有这个

use near_sdk::borsh::{self, BorshDeserialize, BorshSerialize};
use near_sdk::{env, near_bindgen};

near_sdk::setup_alloc!();

#[near_bindgen]
#[derive(Default, BorshDeserialize, BorshSerialize)]
pub struct Counter {
    // See more data types at https://doc.rust-lang.org/book/ch03-02-data-types.html
    val: i8, // i8 is signed. unsigned integers are also available: u8, u16, u32, u64, u128
}

#[near_bindgen]
impl Counter {
  
    pub fn get_num(&self) -> i8 {
        return self.val;
    }

        self.val += 1;
        let log_message = format!("Increased number to {}", self.val);
        env::log(log_message.as_bytes());
        after_counter_change();
    }

 
    pub fn decrement(&mut self) {
       
        self.val -= 1;
        let log_message = format!("Decreased number to {}", self.val);
        env::log(log_message.as_bytes());
        after_counter_change();
    }
    pub fn reset(&mut self) {
        self.val = 0;
        // Another way to log is to cast a string into bytes, hence "b" below:
        env::log(b"Reset counter to zero");
    }
}

fn after_counter_change() {
    // show helpful warning that i8 (8-bit signed integer) will overflow above 127 or below -128
    env::log("Make sure you don't overflow, my friend.".as_bytes());
}

当我运行RUSTFLAGS='-C链接-arg=-s‘货物构建-目标是32未知-未知-释放-我得到这个错误：

错误:链接器cc not file = note:没有这样的文件或目录(os错误2)

错误:由于先前的错误，无法编译proc-macro2

如果我将proc宏2添加到依赖项中，则错误更改为无法编译.“其他依赖项”，并且在试图将它们添加到Cargo.toml时，它会不断添加新的依赖项。

[package]
name = "contract"
version = "0.1.0"
authors = ["Near Inc <hello@nearprotocol.com>"]
edition = "2021"

[lib]
crate-type = ["cdylib", "rlib"]

[dependencies]
near-sdk = "=4.0.0-pre.4"

[profile.release]
codegen-units=1
opt-level = "z"
lto = true
debug = false
panic = "abort"
overflow-checks = true

有什么帮助吗？

Answer 1

不，你只需要安装：

sudo apt install build-essential

编辑(添加更多信息)：

Linux安装程序

不检查编译器工具链，但似乎假设您已经安装了一个C链接器！最好的解决办法是安装尝试过的gcc工具链.

这是我的WSL ubuntu出了点问题，我的货版不同于windows 1，能够用windows构建它。
