Illegal storage access (Mac osx Version 12.3.1)

nimble runr --verbose [11:05:44] Warning: Package 'conway' has an incorrect structure. The top level of the package source directory should contain at most one module, named 'conway.nim', but a file named 'main.nim' was found. This will be an error in the future. Hint: If this is the primary source file in the package, rename it to 'conway.nim'. If it's a source file required by the main module, or if it is one of several modules exposed by 'conway', then move it into a 'conway/' subdirectory. If it's a test file or otherwise not required to build the the package 'conway.nim', prevent its installation by adding skipFiles = @["main.nim"] to the .nimble file.

I have run the code using nimble runr and also nim c -r ./src/main.nim The file compiles just fine but I cannot execute the file.

Code:

`import nico import std/sequtils

let title = "Jonathan's game of life" let wx = 600 let wy = 400 let resolution = 10 let dx = resolution let dy = resolution let nx = wx div dx let ny = wy div dy

var board = newSeqWith(nx, newseqbool) board[0][0] = true board[10][0] = true board[0][5] = true

var buttonDown = false

proc gameInit() = loadFont(0, "font.png")

proc gameUpdate(dt: float32) = buttonDown = btn(pcA)

proc gameDraw() = cls()

setColor(if buttonDown: 7 else: 3)

printc("welcome to " & appName, screenWidth div 2, screenHeight div 2)

setColor(3) boxfill(10,20,100,50)

nico.init("myOrg", title) nico.createWindow("myApp", wx, wy, 1, false) nico.run(gameInit, gameUpdate, gameDraw)`

run it with nimble rund for debug mode and see where it crashes.

Ok , I figured out the issue. It's weird though that this should of failed during the proc and not illegal storage..

Anyway this is why I couldn't see the issue: setColor(3) boxfill(10,20,100,50) where not in scope of the proc at all.

`proc gameDraw() = cls()

setColor(if buttonDown: 7 else: 3)

printc("welcome to " & appName, screenWidth div 2, screenHeight div 2)

setColor(3) boxfill(10,20,100,50)

` Closing ticket.
