Rust Analyser + Symlink to Apps on MacOs = 🤯

[ierehon1905]

Hello, thank you for awesome template.

I encountered issues using it with rust-analyser, it seems that it tried to analyse everything (ok) and even went through symlinks (not ok). Project could not be compiled and everything I got was:

Blocking waiting for file lock on build directory

I was able to solve the issue by deleting the symlink to Applications.
Is this symlink necessary?

The link is used in macOS builds. Mac users can drag and drop the game into their Applications directory (which seems to be standard for installing mac applications).

Maybe you can tell rust-analyser to ignore the build directory? You are using VS code, right? In that case, it would be awesome if we could add a configuration preventing this problem in .vscode. So others don't have to figure it out again.

[NiklasEi]

If that is not possible, we could try to create the symlink during packaging instead of having it in the repository.

Ok, so here is what I have tried unsuccessfully :(

.vscode/settings.json

{
  "rust-analyzer.files.excludeDirs": ["build"],
  "files.watcherExclude": {
    ...
    "**/build/macos/**": true
  }
}

Oh, just found out that it may be not our fault )))

So...

This symlink to /Applications also caused issues for me when simply using cargo run as well.

I added this to my VSCode settings at first:

  "files.exclude": {
    "**/.git": true,
    "**/.svn": true,
    "**/.hg": true,
    "**/CVS": true,
    "**/.DS_Store": true,
    "**/Thumbs.db": true,

    "build/macos/src/Applications": true,
  }

But still ran into build problems until I removed the symlink (seems to be related to rust-lang/cargo#8183):

error: failed to determine package fingerprint for build script for cruise-control v0.1.0 (/Users/ianchamberlain/Documents/Development/cruise-control)

Caused by:
  Permission denied (os error 13)

I just deleted the symlink and all seems to be working as expected now...

[NiklasEi]

If this keeps making trouble I guess it's time to look into generating the symlink when packaging a macOS build.

[NiklasEi]

I just pushed a commit that removes the symlink and instead creates it only during the macOS build. Could you please verify that your issues with the symlink are now gone? Since you have access to a mac: could you please also check if the latest macOS build is still installable via drag and drop to /Applications?

[ian-h-chamberlain]

Both the original issue seems to be gone, and I can install the test app from the .dmg by drag and drop to /Applications.

Thanks for this! I think this issue can be closed now.
