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 包中的 Qt 示例。我能够构建示例，但在创建嵌入式 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 实例时执行被卡住并且没有给出错误。

使用的工作环境

RInside 包：版本 0.2.14

Linux 版本：Red Hat Enterprise Linux Client 5.8 (Tikanga)

R：3.1.1

Rcpp 库：0.11.4

R内部库：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，我正在 rinside_sample0.cpp 中尝试一个更简单的示例。

#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);

}

此代码在运行时也会卡住。它卡在RInside R(argc, argv);

现在，当我将 R_HOME 设置为我的 R 目录时，执行给了我这个错误：

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

谢谢德克的建议。我正在使用的R installation那个是建立在RHEL6我正在研究的RHEL5。所以，我重新安装了 R 包。我在我的机器上安装R 3.1.3了兼容RInside和Rcpp库。RHEL5安装修复后，示例开始运行。

使用的工作环境

RInside 包：版本 0.2.14

Linux 版本：Red Hat Enterprise Linux Client 5.8 (Tikanga)

R：3.1.3

Rcpp 库：0.12.12

R内部库：0.2.14

Qt：4.7.4
