无法打开包含文件："jni.h"：没有此类文件或目录

Question

我正在尝试使用c++版本的语音语音识别API。它是一个用Java构建的API，同时也支持c++。然而，每当我试图执行它时，我就会得到错误

C:UsersyohanDocumentsExtra C++ LibsVoice Recognition - Voce APIvoce-0.9.1srcc++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()
{

}

voice .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..........................................

我怎样才能消除这个错误?我使用的是最新版本的QT，它使用Visual Studio 2010编译器。

您应该引用INCLUDEPATH中包含空格的部分。而不是:

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"
