[Linux] cross compile tmux for Synology DS723+ via DSM 7.1 ToolChain - AMD x86 Linux 4.4.180 (r1000)

終於想不開把家裡的 NAS 升級了，一口氣跳到 AMD Ryzen R1600 型號，接著又要找一下編譯 tmux 的方法 Orz 參考六七年前寫的這篇：[Linux] cross compile tmux for Synology DS216play via DSM 6.1 Tool Chains - STMicroelectronics Monaco Linux 3.10.102 @ Ubuntu 16.04 64bit

過程：

• 使用 tmux3.3a.tar.gz 程式碼
• 使用 libevent-2.1.12-stable.tar.gz 跟 ncurses-6.4.tar.gz 資源庫
• 使用 r1000-gcc850_glibc226_x86_64-GPL.txz 
• 在 macOS @ Apple M1 使用 Docker ubuntu:22.04 編譯

原本找了一台小機器 Ubuntu 18.04 編譯，結果一直出錯，最後還是找個乾淨的機器，一下就搞定。這次用 libevent-2.1.12-stable 時，先略過 openssl 編譯 ，雖然編 openssl 也沒那麼難，但就是這麼懶 XD

~/tmux-3.3a# file tmux

tmux: ELF 64-bit LSB executable, x86-64, version 1 (GNU/Linux), statically linked, for GNU/Linux 3.2.0, with debug_info, not stripped

~/tmux-3.3a# python3 -m http.server 

Serving HTTP on 0.0.0.0 port 8000 (http://0.0.0.0:8000/) ...

還記得當初跑 docker 時有把本機的 18000 port 對到裡頭的 8000 port ，這時就可以靠 http://localhost:18000/tmux 去下載 tmux 來用。

實際運行：

$ uname -a

Linux NAS 4.4.180+ #42962 SMP Thu Dec 8 21:34:11 CST 2022 x86_64 GNU/Linux synology_r1000_723+

$ ~/bin/tmux -V

tmux-tool 3.3a

另外，在 NAS 內運行時，可以多設定 shell 環境資訊：

$ cat ~/.profile 

export PATH=$HOME/bin:$PATH

export TERM=xterm
