我正在使用RInside將R集成到Qt應用程序中。目前，我正在嘗試運行Rinside軟件包中的Qt示例。我能夠構建該示例，但創建嵌入式R實例時執行會停滯。創建嵌入式R實例時執行卡住了

#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(); 
}

在創建嵌入式R實例時執行停滯並且沒有發生錯誤。

工作環境中使用

RInside套餐：發佈0.2.14

版本的Linux：紅帽企業Linux客戶端版本5.8（Tikanga）

R：3.1.1

Rcpp庫：0.11.4

邊緣庫：0.2.14

Qt：4.7.4

任何幫助或建議將不勝感激。謝謝。

更新：

現在，我嘗試rinside_sample0.cpp內一個簡單的例子。

#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);

}

此代碼運行的同時也卡住。它卡住在RInside R(argc, argv);

現在，當我設置R_HOME我[R目錄的執行給了我這個錯誤：

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

幾周前我上次重訪時，仍然在Ubuntu上工作。你需要提供更多的細節，我也會建議嘗試一些更簡單的例子。 –

@DirkEddelbuettel嗨德克，我現在試圖在標準文件夾內運行rinside_sample0示例，但仍面臨同樣的問題。我已經用更多的細節更新了這個問題。請看一看。 – Ayush

您的構建日誌只是部分。我懷疑R可能不會構建爲共享庫，從而無法在該平臺上進行嵌入。 –

謝謝德克的建議。我使用的R installation建立在RHEL6上，我正在研究RHEL5。所以，我做了一個R包的全新安裝。我在我的RHEL5機器上安裝了R 3.1.3和兼容的RInside和Rcpp庫。安裝修復程序後，示例開始運行。

工作環境中使用

RInside套餐：發佈0.2.14

版本的Linux：紅帽企業Linux客戶端版本5.8（Tikanga）

R：3.1.3

Rcpp lib：0.12.12

邊緣庫：0.2.14

Qt：4.7。4
