Execution stuck while creating embedded R instance

I am using RInside to integrate R into a Qt application. Currently, I am trying to run the Qt example present in the RInside package. I am able to build the example but the execution gets stuck while creating an embedded R instance.

#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();
}

The execution is getting stuck while creating the embedded R instance and is giving no errors.

Working Environment Used

RInside Package : Release 0.2.14

Linux version : Red Hat Enterprise Linux Client release 5.8 (Tikanga)

R : 3.1.1

Rcpp lib : 0.11.4

RInside lib : 0.2.14

Qt : 4.7.4

Any help or suggestions would be much appreciated. Thanks.

Update :

Now, I am trying a simpler example inside the rinside_sample0.cpp.

#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);

}

This code is also getting stuck while running. It is getting stuck at RInside R(argc, argv);

Now, when I set R_HOME to my R directory the execution gives me this error:

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

Solution

Thank you Dirk for your suggestion. The R installation that I was using was built on RHEL6 and I was working on RHEL5. So, I did a fresh installation of the R package. I installed R 3.1.3 with the compatible RInside and Rcpp libraries on my RHEL5 machine. After the installation fix the examples started running.
