"llvm-projects" submodule error

Closed this issue · 1 comments

When I use git submodule update --init --recursive command,it showed the following error:

remote: Enumerating objects: 5542844, done.
remote: Counting objects: 100% (5542823/5542823), done.
remote: Compressing objects: 100% (859260/859260), done.
error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly: CANCEL (err 8)
fatal: the remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
Fetched in submodule path 'polygeist/llvm-project', but it did not contain 26eb4285b56edd8c897642078d91f16ff0fd3472. Direct fetching of that commit failed.
Failed to recurse into submodule path 'polygeist'

What is the reason for this happening?

error: RPC failed; curl 92 HTTP/2 stream 0 was not closed cleanly: CANCEL (err 8)

Looking online this error looks simply like an Internet connection issue between your machine and GitHub's server, nothing to do with Dynamatic per se.
