Error running `futhark test`

[samestep]

I'm using Futhark 0.25.11 installed from Homebrew on my 2020 MacBook Pro with M1 chip. Following the futhark test section from the book, I first created this file called matmul.fut:

entry matmul [n][m][p] (x: [n][m]i32) (y: [m][p]i32): [n][p]i32 =
  map (\xr -> map (\yc -> reduce (+) 0 (map2 (*) xr yc))
                  (transpose y))
      x

-- Matrix multiplication.
-- ==
-- entry: matmul
-- input { [[1, 2]] [[3], [4]] }
-- output { [[11]] }
-- input { [[1, 2], [3, 4]] [[5, 6], [7, 8]] }
-- output { [[19, 22], [43, 50]] }

And then I ran it via this command:

futhark test matmul.fut

I am getting the following error:

matmul.fut: getDirectoryContents:openDirStream: does not exist (No such file or directory)

Just to be sure, you're in the right directory when you run futhark test, right? cat matmul.fut works? That error is what you get when the provided file cannot be found.

@athas you're absolutely right, I'm very sorry :joy: should have gone to sleep earlier last night...
