Julia Set - CUDA by example - 帮助我设置项目 [英] Julia Set - CUDA by example - help me set up the project
问题描述
我一直在阅读CUDA by Jason Sanders和Edward Kandrot的例子，他们遇到了第4章，他们使用CUDA解决Julia Set。
另外，书页上有一个源代码; https://developer.nvidia.com/content / cuda-example-introduction-general-purpose-gpu-programming-0
I have been reading CUDA by Example by Jason Sanders and Edward Kandrot and have come across chapter 4 where they solve Julia Set using CUDA. Also, there is a source code available on a books page; https://developer.nvidia.com/content/cuda-example-introduction-general-purpose-gpu-programming-0
当我试图包含项目所需的所有文件文件和.cu），它将无法编译。
我从头开始创建的通常CUDA项目没有问题（VS 2010，CUDA 5.0）。
When I try to include all the files necessary for the project (all header files and .cu ones) it won't compile. My usual CUDA projects that I create from scratch work without problems (VS 2010, CUDA 5.0).
任何人都有同样的问题，每个步骤，以使这个Julia Set设置，因为它应该是？
Did anyone had the same problem and can you please specify each step in order to make this Julia Set set up as it should be?
PS下面是一个不能在头文件中使用的代码：

第一个错误是：
PFNGLBINDBUFFERARBPROC glBindBuffer = NULL;
VS说： IntelliSense：PCH警告：标题停止不能在宏或#if块。
VS says: IntelliSense: PCH warning: header stop cannot be in a macro or #if block. An intellisense PCH file was not generated.
非常感谢。
推荐答案
要正确运行它必须首先从下载源代码：` CUDA by Example源代码
to run it properly you have to first download the source codes from :`CUDA by Example source code
然后解压缩。当你在visual studio中创建项目时，如果是2010和更新版本，你应该去项目属性，去VC ++目录，并将解压后的文件夹添加为包含路径。还可以将lib文件夹添加为库路径，并将bin作为可执行文件路径。
then extract it. when you create your project in visual studio, if it is 2010 and newer you should go to the project properties and go to VC++ Directories and add the extracted folder as an include path. also add the lib folder as library path and the bin as the executable path.
那么您可以将新的cu文件添加到项目中，
then you can add a new cu file to your project and copy the content of the chapter 4 folder -which ever file you want from that- and paste it there and compile it.
如果仍然没有编译，你应该去项目属性 - >链接器并找到附加依赖关系并添加cudart.lib，你都设置了。
if still it doesn't compile, you should go to project properties -> linker and find the "Additional Dependency" and add cudart.lib and you are all set.
还要注意图书代码中的包含词组如下： /.../ common / book.h ，您应该将它们更改为 common / book.h 格式。
also pay attention that the include phrases in the books code are like this: /.../common/book.h , you should change them to common/book.h format.
