clangd not support ccbin when CUDA-based programming

[davidxiaozhi]

When CUDA-based programming is performed, the clangd plug-in displays a message indicating that ccbin is not supported. The error message is as follows

json文件如下

[HighCommander4]

What is the meaning of these flags?

Can they just be ignored for clangd's purposes? If so, you can instruct clangd to ignore it by creating a config file (.clangd) with:

CompileFlags:
  Remove: [-ccbin=*,-rdc=*,-gencode]

@HighCommander4 this is cuda need

[davidxiaozhi]

@HighCommander4 Is there a solution to this problem

[HighCommander4]

Have you tried removing the flags as suggested in this comment?

[davidxiaozhi]

@HighCommander4 I can't remove these flags because cuda c++ programs won't compile properly from the command line,i need it

[HighCommander4]

you can instruct clangd to ignore it by creating a config file (.clangd) with:

CompileFlags:
  Remove: [-ccbin=*,-rdc=*,-gencode]

^ This will only remove the flags from the command line that clangd sees. Your actual build will still use the flags.

@HighCommander4 The .clangd file should be stored in the directory of the engineering root directory in vscode project or below the .vscode directory

[HighCommander4]

@HighCommander4 The .clangd file should be stored in the directory of the engineering root directory in vscode project or below the .vscode directory

It applies to files in the directory tree of the directory containing the .clangd file, so it should go into the project root.
