ファイル Mutex.h のコンパイルに問題があります -> ライブラリ STK (Synthesis Toolkit C++) に属しています。
必要なファイル ("RtWvOut.h"、Mutex.h/cpp、Stk.h/cpp、WvOut.h) をインクルードしたところ、コンパイル中に次の問題が消えました。あなたの答えをありがとう:)
d:\kari\Mutex.h:67: エラー:C2146: 構文エラー: ';' がありません 識別子 'mutex_' d:\kari\Mutex.h:67 の前: エラー:C4430: 型指定子がありません - int と見なされます。注: C++ は default-int d:\kari\Mutex.h:68: Error:C2146: syntax error: missing ';' をサポートしていません 識別子 'condition_' の前に d:\kari\Mutex.h:68: エラー:C4430: 型指定子がありません - int と見なされます。注: C++ は default-int をサポートしていません

/*! \class RtWvOut
\brief STK realtime audio (blocking) output class.
This class provides a simplified interface to RtAudio for realtime
audio output. It is a subclass of WvOut. This class makes use of
RtAudio's callback functionality by creating a large ring-buffer
into which data is written. This class should not be used when
low-latency is desired.
RtWvOut supports multi-channel data in interleaved format. It is
important to distinguish the tick() method that outputs a single
sample to all channels in a sample frame from the overloaded one
that takes a reference to an StkFrames object for multi-channel
and/or multi-frame data.
