Synology 6.1 開發環境建置

因為 Synology 官網的 Synology DSM 6.0 Developer Guide 問題很多,照著走根本不可能把 Package 建立起來,所以怒寫這篇文章。

首先從安裝環境開始,Developer Guide 的 2.1.1. Install Toolkit 就有問題,可以正常運作的指令如下:

mkdir -p /toolkit
git clone https://github.com/SynologyOpenSource/pkgscripts-ng.git

接著 2.1.2 Prepare Build Enviroment 也要修改:

cd /toolkit/pkgscripts-ng
./EnvDeploy -v 6.1 -p x64 # for example

再來 2.1.3 Prepare GPG Key 也有個要修改的地方:

mkdir -p /toolkit/build_env/ds.x64-6.1/root/.gnupg/
cp ~/.gnupg/* /toolkit/build_env/ds.x64-6.1/root/.gnupg/

同時也要注意不要設定密碼,還有 GNU PG 產生今鑰需要亂數。呆翰是遠端到另一台乾淨的 Linux 執行,一開始打鍵盤打個很開心才想起這是遠端。後來直接 sftp 丟了 BanG Dream 的 Android Backup 檔案上去提供了足夠的亂數讓 GNU PG 產生公鑰與私鑰。

接著後面的說明超亂,我建議直接跳到 2.2.5. Summary 直接看結論,了解重要結構。

了解結構後,我們知道原始碼要放在 /toolkit/source 底下,接著我們用 Synology 官方提供的 minialPkg 先試著打包 spk 出來

mkdir -p /toolkit/source
cd /toolkit/source
git clone https://github.com/SynologyOpenSource/minimalPkg.git

接著按照 minialPkg 上的說明建置 package

cd /toolkit
pkgscripts-ng/PkgCreate.py -c minimalPkg

一次成功,打開群輝上傳,安裝,也沒有問題。

一開始在 clone pkgscripts-ng 時,如果後面加上 pkgscripts 讓 script  安裝在 /toolkit/pkgscripts 的話,執行過程會出現以下錯誤:

呆翰一開始進去 /toolkit/build_env/ds.x64-6.1/ 看看有沒有什麼問題,結果發現 pkgscripts 指向 pkgscripts-ng ,而 pkgscripts-ng 不存在,呆翰還手動建立 pkgscripts-ng 資料夾,結果只是變成下面的錯誤:

raise OSError("Cannot call rmtree on a symbolic link")

可見得這文件應該失修一陣子了,而且 6.0 也會有類似的錯誤。

如果已經按照 Developer Guide 建立環境而且出錯,以下的指令可以協助修正那些奇怪的問題:

cd /toolkit/
mv pkgscripts pkgscripts-ng

別浪費時間重建環境了,浪費兩個小時重建又多方測試,已經確定這樣就可以了。

spk 包起來確定環境沒問題後,再回頭詳讀 Developer Guide 把需要的東西改一改開始打包自己的 App 吧。
