Cannot install Pecker on macOS Big Sur 11.3 (beta)

[christiankm]

I cannot install Pecker on Big Sur (possibly due to being beta, but maybe you know).

If trying via Homebrew it throws an error, and trying a manual install via make install throws the following build error:

I have the same problem. @christiankm did you resolve this problem ?

No, I have not looked further into this. But it does not work on 11.3 Beta 1.

I did it (finally). But the problem wasn't the Big Sur, It was Xcode itself I had to select the correct version of xcode using sudo xcode-select -s /Applications/Xcode-12.4.0.app then run the make instal command.

For me the error was following:

.build/checkouts/swift-argument-parser/Sources/ArgumentParser/Parsable Properties/Flag.swift:273:1: note: where 'Value' = 'Bool' extension Flag where Value == Int { ^

I think the issue is in the wrong dependency.

.package(url: "https://github.com/apple/swift-argument-parser.git", .branch("main"))

change it to some stable release

.package(url: "https://github.com/apple/swift-argument-parser.git", from: "0.3.2")

I was hitting this same issue. Looks like the compiler cannot differentiate between the init for Bool and Int, so I replaced line 22 in /Sources/Pecker/PeckerCommand.swift:

// before
@Flag(name: .shortAndLong, help: "Print the version and exit")
// after
@Flag(name: .shortAndLong, inversion: .prefixedNo,  help: "Print the version and exit")
