Include debug information

Execute in the root of your project the command haskell-language-server --debug . and paste the logs here:

Too much to post here. HLS run from the command line compiles the project just fine and exits normally.

Paste the logs from the lsp-client, e.g. for VS Code

Probably a duplicate of #2087

[tscholak]

Hmm, I've built hls from rev 790afc6 which was head in master yesterday.

What strikes me here is that I don't get any useful debug output at all, the log is almost empty.

Something else to note is that I'm building hls with dynamic linking, see the linked "build configuration" above for more details.

[pepeiborra]

#2087 was fixed in the Haskell vscode extension, are you on the latest version?

[tscholak]

@pepeiborra I'm on 790afc6 which was the latest version until 5 minutes ago.

[pepeiborra]

@pepeiborra I'm on 790afc6 which was the latest version until 5 minutes ago.

I am talking about the vscode extension

[tscholak]

I'm on v1.6.0

[tscholak]

I was on v1.4.0 on the machine where I observed the problem. When I updated to v1.6.0, the problem went away.
