Question

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实例时执行会被卡住。

#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();
}

创建嵌入式R实例时执行陷入困境，并且没有错误。

使用的工作环境

RInside Package：发布0.2.14

Linux版本：红帽企业Linux客户端版本5.8（Tikanga）

R：3.1.1

Rcpp lib：0.11.4

RInside lib：0.2.14

Qt：4.7.4

非常感谢任何帮助或建议。感谢。

现在，我在rinside_sample0.cpp中尝试一个更简单的例子。

#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);

}

此代码在运行时也会卡住。它被卡在RInside R(argc, argv);

现在，当我将R_HOME设置为我的R目录时，执行会给我这个错误：

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

感谢Dirk的建议。我使用的R installation是基于RHEL6构建的，我正在RHEL5上工作。所以，我做了R包的全新安装。我在R 3.1.3计算机上安装了RInside与兼容的Rcpp和RHEL5库。安装修复后，示例开始运行。

使用的工作环境

RInside Package：发布0.2.14

Linux版本：红帽企业Linux客户端版本5.8（Tikanga）

R：3.1.3

Rcpp lib：0.12.12

RInside lib：0.2.14

Qt：4.7.4
