successfully intall fortls in linux but don't work in VS code using ssh

[GYC-lab]

Description
I use ssh in my PC's VS code(which is installed in Win11) to connect the supercomputer whose system is linux. When I use fortls --version, it returns the correct result 2.13.0, which means fortls is installed successfully. But when I view my code in my PC's VS code, it still reports no fortls.

So how can I make the fortls actually work and enjoy it on my PC's VS code? Or how to make my PC's VS code installed in Win11 loacte fortls installed in the linux?

Best Regards!

With VS Code's SSH extensions what you end up doing is install a copy of vscode and all the extensions you are using in your remote machine and your local machine simply connects to that. So to get fortls on your remote machine you actually need to install it in your remote machine with pip, see the Docs: https://gnikit.github.io/fortls/quickstart.html#download. Assuming that your windows machine has the pip install location to its PATH you should be good to go, else you need to set the "fortran.fortls.path": "fortls" setting to the absolute path to fortls.

Thanks for your reply!
I have tried to set the "fortran.fortls.path": "fortls" setting to the absolute path to fortls, and it seemed that, my PC's VS code can locate fortls successfully. However, there is an error about launching fortls, like this:

[GYC-lab]

FYI, the version of fortls is 2.13.0.

That message says that you have successfully launch fortls, but some of the options you input are wrong. These are all the valid configuration options https://gnikit.github.io/fortls/options.html what are your fortls options in your remote machine?

[GYC-lab]

OK. FYI, I haven't set any configuration of fortls yet. I will try it refering to https://gnikit.github.io/fortls/options.html. And thanks again*^____^*

No worries, I would do a sanity check on your remote machine to test that fortls is correctly picked up.

for Linux/OS X

which fortls

or Windows

where fortls

and then if fortls is found I would go to a Fortran file and try something like

fortls --debug_filepath your_file.f90 --debug_rootpath . --debug_parser

Is this yields an output then you are good.
Another place to check is the Log Channel in VS Code, check Modern Fortran and see if you see anything suspicious in the output.
