Xcode 12.2 Error: "illegal hardware instruction swift run komondor run" and "Illegal instruction: 4 $komondor run pre-commit $gitParams"

[mhays118]

Hello,

I am trying to integrate Komondor into the codebases I work on. After setting it up, I started getting illegal instruction errors from Komondor and am unable to get it to run in any project.

This happens both when a git-hook runs:
git commit -m "test"

Fatal error: Error raised at top level: PackageConfig.Error(reason: "Could not find a file at /var/folders/nh/x1j0l91x28z35srsgltt4scc0000gn/T/package-config - something went wrong with compilation step probably"): file /AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-1103.8.25.8/swift/stdlib/public/core/ErrorType.swift, line 200
.git/hooks/pre-commit: line 21: 80427 Illegal instruction: 4  $komondor run pre-commit $gitParams

or when I manually try running:
swift run komondor run

Fatal error: Error raised at top level: PackageConfig.Error(reason: "Could not find a file at /var/folders/nh/x1j0l91x28z35srsgltt4scc0000gn/T/package-config - something went wrong with compilation step probably"): file /AppleInternal/BuildRoot/Library/Caches/com.apple.xbs/Sources/swiftlang/swiftlang-1103.8.25.8/swift/stdlib/public/core/ErrorType.swift, line 200

I then modified the package.swift file to the following:

// swift-tools-version:5.3
// The swift-tools-version declares the minimum version of Swift required to build this package.

import PackageDescription

let package = Package(
    name: "TestKomondorPackage",
    products: [
        // Products define the executables and libraries a package produces, and make them visible to other packages.
        .library(
            name: "TestKomondorPackage",
            targets: ["TestKomondorPackage"]),
    ],
    dependencies: [
       .package(url: "https://github.com/shibapm/Komondor.git", from: "1.0.0"),
    ],
    targets: [
        .target(
            name: "TestKomondorPackage",
            dependencies: []),
        .testTarget(
            name: "TestKomondorPackageTests",
            dependencies: ["TestKomondorPackage"]),
    ]
)

#if canImport(PackageConfig)
    import PackageConfig

    let config = PackageConfiguration([
        "komondor": [
            "pre-commit": "swift test",
            "pre-push": "swift test"
        ],
    ])
#endif

run swift run komondor install

Now, I get either of the errors I mentioned above.

Environment Details:

macOS: Catalina 10.15.7 (19H15)
Swift: Apple Swift version 5.3.1 (swiftlang-1200.0.41 clang-1200.0.32.8) Target: x86_64-apple-darwin19.6.0
Xcode: Version 12.2 (12B45b)

Attempted workarounds

Similar issues

This is similar to #28, however, the solution presented ##28 (comment), doesn't seem to work.

I've tried running the solution from that PR multiple times, same issue.

swift package reset
swift run komondor install
swift run komondor run

Tried multiple versions of Komondor

Komondor versions tested: 1.0.6, 1.05, 1.04.

All three of these versions have the same issue.

Changing the swift-tools-version

I've tried changing the swift-tools-version in package.swift to 5.3, 5.1, and 4.2.

Same issue with all these tool versions.

Hey @mhays118, Had the same issue yesterday, fixed by adding write() to the PackageConfiguration

E.g:

let config = PackageConfiguration([ "komondor": [ "pre-commit": [ ... ], ], ]).write()

I updated Xcode to 13.0 and have the same issue mentioned in original post but my PackageConfiguration already has .write().

Is there any other solution I can try??

[cerupcat]

I also already have .write() as part of the PackageConfiguration.

Any other ideas how to fix this?

[Marquis103]

Same...not working for me either...already have .write(). using swift-tools 5.4
