How to make clangd works with cuda files

[davidAlgis]

How to make clangd works with cuda files ? Do I need some specific compilation flags ? I saw on clangd FAQ that we must ensure that the plugin enable clangd when opening cuda files. Is it possible with this plugin ?

[rchl]

Which syntax are you using for cuda files? It's shown in the bottom-right corner, inside the status bar.

must ensure that the plugin enable clangd when opening cuda files. Is it possible with this plugin ?

If you are seeing clangd in the bottom-left corner of the status bar then it means it's running.

You need to add the base scope to the selector https://github.com/sublimelsp/LSP-clangd/blob/92e0fe4f2977a27b5f1e47d5254bf69a0798dfc5/LSP-clangd.sublime-settings#L14

@rchl I'm seing clangd, but it seems to don't know the existence of cuda header. The errors are In included file "cuda_runtime.h" file not found clangpp(file not found). Moreover, the project is built correctly with msbuild.

@rwols I already did it, I even add cuda source file : "selector": "source.c | source.c++ | source.objc | source.objc++ | source.cuda-c++"

Can you capture logs from the LSP? You can enable logging in the LSP (not LSP-clangd) settings.

It might be possible that we need to add the language ID to https://github.com/sublimelsp/LSP/blob/main/language-ids.sublime-settings. I believe Sublime sends cuda-c++ but it should be cuda-cpp.

[rchl]

As far as logs, those are enabled by default and can be seen after opening the log panel with LSP: Toggle Log Panel command.

Here are my log, I just open a simple test file test.cpp with only one line #include "cuda_runtime.h

I never used Cuda myself, but isn't the file type .cu? Also, do you have the Cuda package installed and Cuda selected in the bottom-right corner?

[davidAlgis]

Indeed, the file type in Cuda are cu file that will be compiled with a cuda compiler : nvcc. But even for .cpp or .h files when I want to include cuda headers I have an error of file not found. @LDAP what do you mean by "Cuda package" ? if you're talking about this one it's already installed. For .cu files I selected CUDA in the bottom-right corner.

[rchl]

As far finding the cuda headers, the FAQ seems to say that if you have problems with that then you should pass --cuda-path=.... Maybe LDAP can answer on how exactly this can be done with this package. Is it through package settings or compile commands rather?

As for handling *.cu files, you haven't provided logs for that but I'm guessing the language ID has to be cuda (googled a bit). So open Preferences: LSP Language ID Mapping Overrides and add:

"source.cuda-c++": "cuda"

[LDAP]

Yes I meant that package.

If you can't find Cuda headers even in regular cpp files then this is likely an issue with clangd or with your toolkit installation.

If the server does not work correctly only in Cuda files then it could be because the language id must be added (I think we should add that regardless).

[LDAP]

@rchl according to https://code.visualstudio.com/docs/languages/identifiers it's cuda-cpp

[davidAlgis]

@rchl ok I add it in Language mapping. Sorry for the log, I wanted to make it very simple, but I forget to open a .cu file... Here is a version where I open test.cu with only the same include as the one above.

I will check if the cuda path has been well defined.

[davidAlgis]

The problem seems to be solved by adding the include of cuda in the include folder of clangd... But it's a bit dirty ^^

[rchl]

@rchl according to code.visualstudio.com/docs/languages/identifiers it's cuda-cpp

I don't know then. I've seen some google results where people are passing cuda. Even tried to find some references to it in clagnd code but couldn't find any which makes me think that it might not care and just follow the file extension...

[davidAlgis]

As it works when adding cuda include in the include folder of clangd. I tried to add --cuda-path option to clangd, but the option doesn't seems to exists in clangd arguments (I have not seen it with --help). So where should I add this option ? In compile commands ?

[LDAP]

So where should I add this option ?

This should be an option for clang, not clangd. You should add it into your compilation database.

[davidAlgis]

Ok thanks @LDAP ! Sorry I'm a bit a beginner on clang, have you any idea how i can add this option in compilation database ?

[LDAP]

I do not use Cuda myself, but the workflow should be as follows:

You need a compile_commands.json or compile_flags.txt file (see https://github.com/sublimelsp/LSP-clangd#usage) you can manually edit these files and add the option where necessary. Ideally, the generator of those files adds the option for you - maybe you need to tweak your build system to detect Cuda (regenerating the files would overwrite your customization).

[davidAlgis]

@LDAP thanks for the details.

[davidAlgis]

I found a similar issue on the github of vscode clangd extenstion.

I solve this by adding a .clangd file at the root of my project :

CompileFlags:
  Add:
    - --cuda-path=C://Program Files//NVIDIA GPU Computing Toolkit//CUDA//v12.1
    - -LC://Program Files//NVIDIA GPU Computing Toolkit//CUDA//v12.1//lib
    - -IC://Program Files//NVIDIA GPU Computing Toolkit//CUDA//v12.1//include
