オープンソースプログラムの管理スクリプト

GNUビルド後にオープンソースを使用しようとしたとき、次のような奇妙なことが起こりました。

1. ./configure ./make ./make install でエラーが発生しませんでした。

2. この管理スクリプトには、使用しようとすると初期化された値を持たない変数がいくつかあります。スクリプトは「ionadmin」と呼ばれ、これらのNULL変数の1つは、たとえば「NO_GLOB_SUBST」です。

3. ドキュメントにこの名前 "NO_GLOB_SUBST"が見つかりません。そうしないと、以下を使用してルートパスで割り当てタスクを見つけることができません。

   ~/ -type f |xargs grep 'NO_GLOB_SUBST' 検索

そしてスクリプトは次のようになります。

# libraries that it depends on are installed.

私の質問は次のとおりです。 このスクリプトの作成者は、どのような状況で初期化されていない変数を使用しましたか？それともいくつかのエラーを見落としていますか？別の質問も投稿しました。カチッという音
