在使用g ++和gcc

Question

我正在尝试配置我的netbeans来处理我的并行编程C ++代码。我可以使用命令行（cygwin）编译该代码，但现在为了进一步调试和编码更复杂的事情，我想转移到一些IDE和选择的neatbeans来完成我的任务。有人建议我在netbeans中单击构建我的应用程序按钮后，如何添加-fopenmp来编译我的应用程序。 （已经使用netbeans_配置了GCC和G ++。以下是我使用netbeans构建代码时出现的错误：

    cd 'D:\University\PARALLEL\ParallelTesting'
C:\dev_softwares\cygwin64\bin\make.exe -f Makefile CONF=Debug
"/usr/bin/make" -f nbproject/Makefile-Debug.mk QMAKE= SUBPROJECTS= .build-conf

collect2: error: ld returned 1 exit status
nbproject/Makefile-Debug.mk:62: recipe for target 'dist/Debug/Cygwin-Windows/paralleltesting.exe' failed

p.s：并行编程世界的新手，已经使用netbeans配置了gcc。

我的测试并行代码：

#include <omp.h>
#include <stdio.h>
#include <stdlib.h>

int main (int argc, char *argv[]) 
{
int nthreads, tid;

/* Fork a team of threads giving them their own copies of variables */
#pragma omp parallel private(nthreads, tid)
  {

  /* Obtain thread number */
  tid = omp_get_thread_num();
  printf("Hello World from thread = %d\n", tid);

  /* Only master thread does this */
  if (tid == 0) 
    {
    nthreads = omp_get_num_threads();
    printf("Number of threads = %d\n", nthreads);
    }

  }  /* All threads join master thread and disband */

}

以下是我所做的工作。感谢@Hristolliev。

  

如果它是托管C / C ++项目，那么编译器选项可以是   在项目属性中指定 - ＆gt;构建 - ＆gt; C ++编译器 - ＆gt;   附加选项。
