is emacs running on your local lap/desktop? Or are you running it on a machine you ssh'ed into ? And that from that machine, you tramp into another?
Tramp is just filling the buffer with under the hood calls to `scp` if the code is in you local machine's buffer, I don't see how the eglot would not work.
If you are not running emacs on your local Mac, you should try to do so. So start emacs on your local Mac and try to do a multi-hop tramp:
the hops can be any level, but, more levels means more lag. I don't have time to test my theory now. Might do so over the weekend.
Yes eMacs is running on my local laptop.
If I try running eglot on a local file (on my laptop) all is well - it immediately finds the language server binary and runs it fine.
However, if attempt it on a remote file (opened over tramp) it says it can’t find the binary and prompts me to point it at it. I could do that, but then the language server would start on that same machine and that’s a no go since it’s a shared login machine.
So ideally I’d be able to tell it to use a language server running on my laptop but have been unable to get that to happen.
oh, that sucks. I did not understand the LSP's requirements:

the language servers are pretty simple C/C++ programs. If you have access to gcc/g++ on the target machine, you could try compile/running them in the BG just as a command line prgram. you would not need to `sudo blah install` anything.
