Question

我正在尝试使用Rcpp

编译以下代码

#include <Rcpp.h>
#include <boost/thread.hpp>
using namespace Rcpp;

// parallelization test
void workerFunc()
{

  boost::posix_time::seconds workTime(3);
  std::cout << "Worker: Running" << '\n';
  //boost::this_thread::sleep(workTime);
  double k=1;
  for (int i = 1; i<100000000; ++i)
    k = k*sqrt(i);
  std::cout<< "Worker: Finished" << '\n';
}

// [[Rcpp::export]]  
void parallelTests() {
  // creates threads and joins them
  std::vector<boost::thread *> z;

  for (int i = 0; i < 15; ++i)
    z.push_back(new boost::thread(workerFunc));

  for (int i = 0; i < 15; ++i)
  {
    z[i]->join();
    delete z[i];
  }
}

收到以下错误

我的增强版安装随后来自以下发行版MINGW Distro

我在R中设置路径，然后编译

Sys.setenv("PKG_CXXFLAGS"="-I C:/mingw/MinGW/include")
Sys.setenv("PKG_LIBS"="-L C:/mingw/MinGW/lib")
Rcpp::sourceCpp('C:/temp/kvasvn/kva/CppThreadTest.cpp', verbose=TRUE)

你知道造成这种情况的原因吗？

编辑1：

好的第一个错误是由包含其他版本libstdc的C：/ mingw / MinGW / lib目录引起的。我刚刚将libboost_thread.a复制到C：/ mingw / MinGW / myFolder并包含了。现在有其他错误

boost :: system :: system_error的另一个定义在哪里，我不明白？
