Cuda update

[OpportunityLiu]

CUDA 11相关支持

[waruqi]

剩下那两处稍微改下吧

[OpportunityLiu]

装了一堆东西，现在不加这两句就找不到头文件了，知道啥情况吗？

   add_includedirs("/usr/include/c++/9")
   add_includedirs("/usr/include/x86_64-linux-gnu/c++/9")

[waruqi]

额 找不到啥头文件？是不是编译器的问题 用了clang9? 装了多个版本clang?

[OpportunityLiu]

前一个是<new> 后一个是<bits/c++config.h>

In file included from /usr/local/cuda/bin/../targets/x86_64-linux/include/cuda_runtime.h:115:

/usr/include/c++/9/new:39:10: fatal error: 'bits/c++config.h' file not found

[waruqi]

不太清楚 可以设下-stdlib=libc++ 试试，我明天也搞个linux环境试试

[OpportunityLiu]

换了gcc就好了，clang就有这个问题，直接/usr/local/cuda/bin/nvcc -allow-unsupported-compiler -ccbin=clang src/main.cu 也一样

[OpportunityLiu]

顺便，用clang的话，默认的c-console模板也编译不过去，一样的问题

而且ccbin默认会用clang是怎么回事啊

[OpportunityLiu]

装了libstdc++-10-dev好了，clang还认死一个版本的啊

现在用clang报这个

不过按理说装了clang10应该就有这玩意的啊，apt被我折腾坏了？

clang怎么会跑到 lib/gcc/ 的 c++库里面去？用的是gcc的stdc+++?

按理装完clang10 自带这些的 回头我试试

[waruqi]

感觉像是你这环境问题，我这边测了下nvcc11+ gcc/clang 都可以么。。不过我的ubuntu 比较老 暂时没 clang10 ，pie有没有都ok

To make

sure always the most recent versions of the packages are installed, we are providing some default packages.
To install all of them (currently version 12):
apt-get install clang-format clang-tidy clang-tools clang clangd libc++-dev libc++1 libc++abi-dev libc++abi1 libclang-dev libclang1 liblldb-dev libllvm-ocaml-dev libomp-dev libomp5 lld lldb llvm-dev llvm-runtime llvm python-clang

看着现在似乎还要额外安装最新的版本 libc++-dev libc++1 libc++abi-dev libc++abi1 啥的。。
