前言
真香注意
由於此板子需要遵守廠商規則必須 build 成-static 的程式，但是 avahi-daemon 本身會 build 成 -shard 的程式，所以我們必須修改相關的 makefile，所以單純的./configure 已經沒辦法滿足，看不懂我在工三小就直接往下看。
avahi-daemon 移植 imxrt1064(arm-v7-linux-uclibceabi)
以下請自行準備相關 toolchain，並遵照廠商提供的編譯方法。
1.下載 4 個 tar 包
自行解壓縮到指定資料夾，本文示範如下
$ tree -L 1 ~/Desktop/avahi-daemon-imxrt1064/
/home/yuyan/Desktop/avahi-daemon-imxrt1064/
├── avahi-0.7
├── expat-2.2.9
├── libdaemon-0.14
└── attr-2.5.1
4 directories, 0 files
2.編譯 libdaemon
#因為產生再/opt底下，所以切至root權限
$sudo -s
#設置
$./configure --host=arm-v7-linux-uclibceabi --prefix=/opt/imxrt1064/libdaemon CC=arm-v7-linux-uclibceabi-gcc \
--config-cache
#錯誤訊息:
configure: error: cannot check setpgrp when cross compiling
#訂正方法:
$echo "ac_cv_func_setpgrp_void=yes" > config.cache
# 再次執行
$./configure --host=arm-v7-linux-uclibceabi --prefix=/opt/imxrt1064/libdaemon CC=arm-v7-linux-uclibceabi-gcc \
--config-cache
$make
# 會碰到這些錯誤
CCLD libdaemon.la
.libs/dfork.o: In function `daemon_fork':

# 因為uclinux 沒有fork這東西所以全部用vfork 代替
---
# 將這2個文件內的 fork 全部替換成 vfork
$vim /home/yuyan/Desktop/avahi-daemon-imxrt1064/libdaemon-0.14/libdaemon/dfork.c
$vim /home/yuyan/Desktop/avahi-daemon-imxrt1064/libdaemon-0.14/libdaemon/dexec.c
$make
$make install
3.編譯 expat (如果 toolchain 沒有的話)
#解壓縮
$bzip2 -d expat-2.2.9.tar.bz2ls
$tar xvf expat-2.2.9.tar ./
#因為要產生在/opt底下，所以切至root權限
$sudo -s
$./configure --host=arm-v7-linux-uclibceabi --prefix=/opt/imxrt1064/expat-2.2.9 CC=arm-v7-linux-uclibceabi-gcc
$make
$make install4.編譯 libattr (如果 toolchain 沒有的話)(可選)
(20220718 補充) 編譯流程跟expat差不多 <= 有需要調整請自行修正
我不確定這隻cross compiler 需不需要自己build這個 lib，如果avahi需要的話，在build好此lib 在CFLAGS 跟LDFLAGS 補上
#解壓縮
$tar zxvf attr-2.5.1.tar.gz
$sudo -s
$./configure --host=arm-v7-linux-uclibceabi --prefix=/opt/imxrt1064/attr CC=arm-v7-linux-uclibceabi-gcc
$make
$make install5.編譯 avahi
這邊目的只在於編譯 avahi-daemon，所以其他的工具都會 disable。
