Я пытаюсь создать небольшое приложение на c ++, которое сохраняет мидиафайлы с помощью этой библиотеки.http://musicnote.sourceforge.net/docs/html/index.html
Пример кода, который приводится на домашней странице, выглядит следующим образом.
#include "MusicNoteLib.h"
void main()
{
MusicNoteLib::Player player; // Create the Player Object
player.Play("C D E F G A B"); // Play the Music Notes on the default MIDI output port
}
Этот фрагмент кода не будет компилироваться в Visual studio 2008, я получаю много ошибок, например
MusicNoteLib.h (22): ошибка C4430: отсутствует указатель типа - предполагается использование int.Примечание: C ++ не поддерживает default-int
Я не понимаю ошибку или с чего начать поиск ... Также были некоторые dll-файлы, которые можно использовать вместо этого h-файла.
