C++/c 혼란

Question

나는이 라이브러리로 midifiles를 저장하는 C++의 작은 응용 프로그램을 만들려고합니다. http://musicnote.sourceforge.net/docs/html/index.html

홈페이지에 제공되는 샘플 코드는 다음과 같습니다. 오류 C4430 : 누락 된 형식 지정자 - 가정 int로

#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 
    } 

, 나는

MusicNoteLib.h처럼 (22) 많은 오류를 비주얼 스튜디오 2008에서 컴파일되지 않습니다이 코드 조각을 얻는다. 참고 : C++가 지원하지 않는 기본-INT

내가 찾고 시작하는 오류 또는 어디를 이해하지 않습니다 ... 대신이 시간의 파일을 사용할 수 있습니다 일부 dll 파일은 있었다.

Answer 1

오류는이 라인에 : 나는 "분노"C/C++ 않았기 때문에

typedef void (__stdcall *LPFNTRACEPROC)(void* pUserData, const TCHAR* szTraceMsg); 

그것은 내가 여기에 조금 녹슬 동안이었다. 어딘가에 유형 불일치가 있습니다. 실제로는 _T 매크로에 문자열을 래핑하여 발견했습니다.

Answer 2

CPP 파일에 MusicNoteLib.h를 포함하기 전에 LPFNTRACEPROC 및 TCHAR을 선언하는 헤더를 포함해야합니다. 그것은 아마도 ChrisF가 제안한 것처럼 주석 처리해서는 안되는 Player.h 일 수도 있고 Windows 헤더 일 수도 있습니다.

기본 개념은 컴파일러가 불평하는 줄을보고, 그 줄의 기호가 어디에 선언되는지 알아 내고 그 선언이있는 적절한 헤더 파일을 포함해야한다는 것입니다.
