Qt与CUDA相结合具体的操作主要修改qt项目中的配置文件pro。下面以测试的项目为例。

因为这是一个测试案例，代码很简单，下面将这几个文件的代码贴出来，方面后面对应pro文件和Makefile文件中的内容。

1.main.cpp

1 #include "mainwindow.h" 2 #include 
     
       3  4 int main(int argc, char *argv[]) 5 { 6     printf("main1 \n"); 7  8     QApplication a(argc, argv); 9     MainWindow w;10     w.show();11 12    printf("main2 \n");13     return a.exec();14 }

2.mainwindow.cpp

1 #include "ui_mainwindow.h" 2 #include "binlinearinterpolationcuda.h" 3  4  5 MainWindow::MainWindow(QWidget *parent) : 6     QMainWindow(parent), 7     ui(new Ui::MainWindow) 8 { 9     ui->setupUi(this);10     printf("MainWindow \n");11 12     BinlinearInterpolation();//cuda代码的入口13 }14 15 MainWindow::~MainWindow()16 {17     delete ui;18 }

3.binlinearinterpolationcuda.cu

1 #include "binlinearinterpolationcuda.h" 2  3  4 __global__ void Binlinear1_kernel(float *M,float *N,int *x,int *width1); 5 __global__ void Binlinear2_kernel(float *N,float *V,int *y,int *width1); 6 void BinlinearInterpolation(){ 7 /****/ 8     Binlinear1_kernel<<
     
      >>(M,N,x,width1); 9     Binlinear2_kernel<<
      
       >>(N,V,y,width1);10 /***/11     12 }

4.binlinearinterpolationcuda.h

1 #ifndef BINLINEARINTERPOLATIONCUDA_H 2 #define BINLINEARINTERPOLATIONCUDA_H 3 #include "cuda_runtime.h" 4 #include "device_launch_parameters.h" 5 #include 
     
       6 #include "malloc.h" 7 #define  WIDTH 11 8  9 #define  HEIGHT 1010 #define  X_INTER 311 #define  Y_INTER 312 #define  BLOCK_SIZE 813 14 void BinlinearInterpolation();15 #endif // BINLINEARINTERPOLATIONCUDA_H

5.mainwindow.h

1 #ifndef MAINWINDOW_H 2 #define MAINWINDOW_H 3  4 #include 
     
       5  6 namespace Ui { 7 class MainWindow; 8 } 9 10 class MainWindow : public QMainWindow11 {12     Q_OBJECT13 14 public:15     explicit MainWindow(QWidget *parent = 0);16     ~MainWindow();17 18     void creatMenu();19 20 private:21     Ui::MainWindow *ui;22  23 24 };25 26 #endif // MAINWINDOW_H

6.pro文件的配置

pro文件的配置是参照http://blog.163.com/qimo601@126/blog/static/15822093201401305739673/中提到的方法。该方法非常适用，比其他需要修改Makefile文件的方法更加实用。

7.修改完pro文件后，就可以qmake->make->执行目标文件

8.Makefile文件

有兴趣的同学，可以根据pro文件中的内容都Makefile中的代码。
