NAS g++ で a.out が作成されない?
warning はあるが,エラーの表示はない状態まで修正して g++ .

なのに a.out が作成されない.
Raspberry Pi で同様に動かすと

どうも ShiftJIS のコメントが邪魔してかエラーが表示されてないだけみたい.
未定義となっているので正しく宣言して対応.
次は warning .
.../v2_funca.hxx:28:9: warning: 'vd2_arc::tc' will be initialized after [-Wreorder] double tc ; .../v2_funca.hxx:27:9: warning: 'double vd2_arc::ts' [-Wreorder] double ts ; .../v2_funca.hxx:23:2: warning: when initialized here [-Wreorder] vd2_arc () : lr(0) , tc(0) , ts(0) {}
これは,クラス内の変数の宣言と初期化の順番が異なる場合のものらしい.
もう一つの [-Wunused-but-set-variable] は戻り値を使用していないもの.
warning: variable 'lm' set but not used [-Wunused-but-set-variable]
変数を削除して対応.
前後するが 先日のツール で ShiftJIS のソースを UTF-8 に.
