java - 无法打开包含文件 : 'jni.h' : No such file or directory

Question

我正在尝试使用 voce 的 C++ 版本语音识别API。它是一个用 Java 构建的 API，也支持 C++。但是，每当我尝试执行它时，我都会收到错误

C:\Users\yohan\Documents\Extra C++ Libs\Voice Recognition - Voce API\voce-0.9.1\src\c++\voce.h:34: error: C1083: Cannot open include file: 'jni.h': No such file or directory

这是我的 .pro 内容

这是Main.cpp

的代码

#include "C:/Users/yohan/Documents/Extra C++ Libs/Voice Recognition - Voce API/voce-0.9.1/src/c++/voce.h"

int main()
{


}

voce.h的一小部分代码如下

#ifndef VOCE_H
#define VOCE_H

// This file contains a C++ interface for Voce's Java functions.  All of 
// the Java methods in Voce's API are instance methods, so we don't need 
// to handle class methods here.  For documentation on the specific 
// functions, refer to the API documentation for the Java source.

#include <jni.h>
#include <iostream>
#include <string>

/// The namespace containing everything in the Voce C++ API.
namespace voce
{
#ifdef WIN32
const std::string pathSeparator = ";";
#else
const std::string pathSeparator = ":";
#endif

    /// Contains things that should only be accessed within Voce.
    namespace internal
    {
        /// Global instance of the JNI environment.
        JNIEnv* gEnv = NULL;

        /// Global instance of the Java virtual machine.
        JavaVM *gJVM = NULL;

//Code Continues..........................................

我怎样才能摆脱这个错误？我正在使用 QT，这是使用 Visual Studio 2010 编译器的最新版本。

您应该引用 INCLUDEPATH 中包含空格的部分。而不是做:

INCLUDEPATH += C:/Program Files/Java/jdk1.7.0/include/
INCLUDEPATH += C:/Program Files/Java/jdk1.7.0/include/win32

你可能应该这样做:

INCLUDEPATH += "C:/Program Files/Java/jdk1.7.0/include/"
INCLUDEPATH += "C:/Program Files/Java/jdk1.7.0/include/win32"
