我正在使用RInside将R集成到Qt应用程序中。目前，我正在尝试运行Rinside软件包中的Qt示例。我能够构建该示例，但创建嵌入式R实例时执行会停滞。创建嵌入式R实例时执行卡住了

#include <QApplication> 
#include "qtdensity.h" 

int main(int argc, char *argv[]) 
{ 
    qDebug() << "First"; 
    RInside R(argc, argv);   // Execution halts at this point 
    qDebug() << "Second"; 
    QApplication app(argc, argv); 
    QtDensity qtdensity(R);  // pass R inst. by reference 
    return app.exec(); 
}

在创建嵌入式R实例时执行停滞并且没有发生错误。

工作环境中使用

RInside套餐：发布0.2.14

版本的Linux：红帽企业Linux客户端版本5.8（Tikanga）

R：3.1.1

Rcpp库：0.11.4

边缘库：0.2.14

Qt：4.7.4

任何帮助或建议将不胜感激。谢谢。

更新：

现在，我尝试rinside_sample0.cpp内一个简单的例子。

#include <RInside.h>     // for the embedded R via RInside 
#include <iostream> 

using namespace std; 

int main(int argc, char *argv[]) { 
cout << "Starting \n"; 
RInside R(argc, argv);    // create an embedded R instance 
cout << "R instance created\n"; 

R["txt"] = "Hello, world!\n"; // assign a char* (string) to 'txt' 

R.parseEvalQ("cat(txt)");   // eval the init string, ignoring any returns 

exit(0);

}

此代码运行的同时也卡住。它卡住在RInside R(argc, argv);

现在，当我设置R_HOME我[R目录的执行给了我这个错误：

cannot find system Renviron 
Fatal error: unable to open the base package

几周前我上次重访时，仍然在Ubuntu上工作。你需要提供更多的细节，我也会建议尝试一些更简单的例子。 –

@DirkEddelbuettel嗨德克，我现在试图在标准文件夹内运行rinside_sample0示例，但仍面临同样的问题。我已经用更多的细节更新了这个问题。请看一看。 – Ayush

您的构建日志只是部分。我怀疑R可能不会构建为共享库，从而无法在该平台上进行嵌入。 –

谢谢德克的建议。我使用的R installation建立在RHEL6上，我正在研究RHEL5。所以，我做了一个R包的全新安装。我在我的RHEL5机器上安装了R 3.1.3和兼容的RInside和Rcpp库。安装修复程序后，示例开始运行。

工作环境中使用

RInside套餐：发布0.2.14

版本的Linux：红帽企业Linux客户端版本5.8（Tikanga）

R：3.1.3

Rcpp lib：0.12.12

边缘库：0.2.14

Qt：4.7。4
