在Ubuntu 20.04中编译libimobiledevice时出错

Question

实际上，我是在第二次编译libimobiledevice。我很久以前就用过了。但这次我遇到了如下所示的错误：

Configuration for libimobiledevice 1.3.1:
-------------------------------------------

  Install prefix: .........: /usr/local
  Debug code ..............: no
  Python bindings .........: yes
  SSL support backend .....: OpenSSL

  Now type 'make' to build libimobiledevice 1.3.1,
  and then 'make install' for installation.

我使用bash脚本实现自动化：

#!/bin/bash

function build() {
    libs=( "libplist" "libusbmuxd" "libimobiledevice" "usbmuxd" "libirecovery" \
                "ideviceinstaller" "libideviceactivation" "idevicerestore" "ifuse" )

    buildlibs() {
        for i in "${libs[@]}"
        do
            git clone https://github.com/libimobiledevice/${i}.git
            cd $i
            ./autogen.sh
            make && sudo make install
            cd ..
        done
    }

    buildlibs
    if [[ -e $(which ldconfig) ]]; then
        ldconfig
    else
        echo "done"
    fi
}

build
if [[ $(uname) == 'Linux' ]]; then
    sudo ldconfig
fi

我已经安装了以下构建包：

sudo apt-get install \
    build-essential \
    checkinstall \
    git \
    autoconf \
    automake \
    libtool-bin \
    libplist-dev \
    libusbmuxd-dev \
    libssl-dev \
    usbmuxd \
    cython

我做错了什么?你能帮帮我吗？这是我的第一个问题。如果我的问题包含了太多的细节，我很抱歉。

libimobiledevice中有一个bug，需要它链接到libm。那是fixed a couple of days ago，所以我建议你从GitHub获取最新的源代码，然后再试一次。这应该可以解决这个问题。
