有时候需要跑在GPU上运行的cuda程序，如何在QtCreator上编译呢？我本想QtCreator上添加cuda的nvcc编译器，但是设置下拉框里没有NVCC这一项。

我就想，能否用nvcc编译了.cu文件，然后和QtCreator的项目程序编译链接在一起，比较偏门。

执行过程：

1.前提已经安装了cuda工具包,这样你才有nvcc编译器。假如你有myfun.h和myfun.cu文件，编写makefile，或直接在终端使用nvcc 编译.cu文件，生成可执行程序.o文件，假设名为myfun.o 。

2.在项目文件.pro中添加 

     OBJECTS += myfun.o

3.然后使用你的QtCreator构建项目吧。

另外一种通用的方法：

可在.pro文件中添加
