CUDAbyExample环境搭建

git clone https://github.com/CodedK/CUDA-by-Example-source-code-for-the-book-s-examples-.git

首先是报错

nvcc -o ray ray.cu 
In file included from ../common/cpu_bitmap.h:20:0,
                 from ray.cu:19:
../common/gl_helper.h:44:21: fatal error: GL/glut.h: No such file or directory
 #include <GL/glut.h>

google后发现需要

sudo apt-get install  freeglut3-dev

然而出现众多依赖报错

尝试update,但遇到

Err:7 https://cli.github.com/packages stable InRelease                                                                             
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 23F3D4EA75716059

一共有两个key错误.按照这里提供的方法输入

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 23F3D4EA75716059

和另一个,另外一个解决,但这个仍然无法解决.根据这里提供的方法,输入

curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg \
&& sudo chmod go+r /usr/share/keyrings/githubcli-archive-keyring.gpg \
&& echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null \
&& sudo apt update \
&& sudo apt install gh -y

update的问题正常.似乎是密钥未注册.然而freeglut3-dev仍然不能安装,绷.

放弃unix,转向Windows.首先是报错

LINK : fatal error LNK1104: 无法打开文件“glut64.lib”

解决方法是将代码自带的lib文件夹下的glut64.lib复制到代码所在目录(作者你太贴心了).继续编译不会报错,但运行.exe文件时会提示找不到glut64.dll.经多方搜索,解决方法为在VS的bin目录下粘贴代码目录下的bin文件夹内的这个文件.目标目录为C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.26.28801\bin\Hostx64\x64\.注意可能随安装版本不同而有所变化.(PS:我不知道直接将glut64.dll复制到代码目录是否有用,或可一试)
