无法打开包含文件：“jni.h”：没有那个文件或目录。

Question

我正在尝试使用voce语音识别API的C++版本。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，我都会收到错误提示。

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()
{


}

下面给出了 voce.h 代码的一小部分

#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..........................................

我该如何解决这个错误？我正在使用QT，最新版本使用Visual Studio 2010编译器。

@Yohan 好的，但我们必须问这些问题。 - john

你尝试过在这两个 'INCLUDEPATH += C:/Program Files/Java/jdk1.7.0/include/' 条目中引用路径吗？我只是想知道 Program Files 中的空格是否会导致问题。 - spdaley

@AndyThomas-Cramer：QT Creator.. 我正在使用它。 - PeakGen

@spdaley：引用？不是吧..如何以确切的方式做到这一点？ - PeakGen

@Yohan：我以前从未使用过这个，但如果其他SO问题中的一些内容是正确的，那么你只需要在路径周围加上引号...所以INCLUDEPATH += "C:/Program Files/Java/..." - spdaley

Answer 1

你应该引用INCLUDEPATH中包含空格的部分。不要这样做：

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"

查找jni.h没有返回任何结果。我在Ubuntu 13.04机器上安装了Java 1.7。 - w2lame
