安装FireDBG binaries

在这里插入图片描述

(base) pdd@pdd-Dell-G15-5511:~$ curl https://raw.githubusercontent.com/SeaQL/FireDBG.for.Rust/main/install.sh -sSf | sh

error: timeout

手动下载install.sh和x86_64-ubuntu22.04.tar.gz，相关的重要代码如下：
下载函数

# This wraps curl or wget. Try curl first, if not installed,
# use wget instead. 
downloader() {
    if check_cmd curl # 检查是否存在 curl 命令
    then _dld=curl
    elif check_cmd wget # 检查是否存在 wget 命令
    then _dld=wget
    else _dld='curl or wget' # to be used in error message of need_cmd
    fi

    #要使用这个函数下载一个文件，可以这样调用：downloader "https://example.com/file.zip" "downloaded_file.zip"
    # 如果传递的第一个参数是 --check，则检查是否存在 _dld（curl 或 wget）命令
    if [ "$1" = --check ]
    then need_cmd "$_dld"
    # 如果 _dld 是 curl，则使用 curl 下载文件
    elif [ "$_dld" = curl ]
    then curl -sSfL "$1" -o "$2"
    # 如果 _dld 是 wget，则使用 wget 下载文件
    elif [ "$_dld" = wget ]
    then wget "$1" -O "$2"
    # 如果 _dld 不是 curl 也不是 wget，输出错误消息
    else err "Unknown downloader"   # should not reach here
    fi
}

函数在代码中的调用downloader "$_url" "$_file"
需要修改的配置

    local _url="https://github.com/SeaQL/FireDBG.for.Rust/releases/download/$_firedbg_version/$_arch.tar.gz"
    local _dir="$(mktemp -d 2>/dev/null || ensure mktemp -d -t FireDBG)" # $(...)：这是 Bash 中的命令替换语法，表示将命令的输出结果嵌入到字符串中
    local _file="$_dir/$_arch.tar.gz"

修改成如下

    local _url="https://github.com/SeaQL/FireDBG.for.Rust/releases/download/$_firedbg_version/$_arch.tar.gz"
    local _dir="/home/pdd/myrust/mytemp"  
    # local _file="$_dir/$_arch.tar.gz"
    # downloader "$_url" "$_file

结构如下：

安装成功：

FireDBG binaries will be installed in ~/.cargo/bin and a debugger self test will be conducted to verify the installation.
