  Any ideas? - thanks.

      var wnd = newWindow(newRect(40, 40, 800, 600))
      
      # Create a static text field and add it to view hierarchy
      let label = newLabel(newRect(20, 20, 150, 20))

  I think it's because latest nimx only works with nim devel, so try the development branch of Nim please.

  Thanks - I did try that but had another error that I can't recall. I'll try again later.

  I tested it @araq

  Problem with "devel" is that the current Nim compiler is having problems with:

  proc nimxPrivateStringify*[T](v: T): string {.inline.} = $v
  proc nimxPrivateStringify*(v: string): string {.inline.} =
      result = v
      if result.isNil: result = "(nil)"
  
  var currentOffset {.threadvar.}: string
  
  proc logi*(a: varargs[string, nimxPrivateStringify]) {.gcsafe.} =
      if currentOffset.isNil: currentOffset = ""
      native_log(currentOffset & a.join())
  Run

  in "system_logger.nim" of nimx.

  
  testnimx.nim(17, 1) template/generic instantiation from here
  .../sdl_window.nim(335, 14) Error: attempting to call undeclared routine: 'nimxPrivateStringify'
  Run

  You can clone and install nimx and then change line 58 in "system_logger.nim" from

  
  proc logi*(a: varargs[string, nimxPrivateStringify]) {.gcsafe.} =
  Run

  to

  
  proc logi*(a: varargs[string, `$`]) {.gcsafe.} =
  Run

  as workaround until the compiler gets fixed. This will of course weaken the error reporting of nimx overall.

  Or you can import nimx.system_logger in the main file. Updated example and filed a bug.

  With the 14.2 I get the same error.

  So with devel I now get

  I haven't tried OderWat's suggestion yet.

  What setup are you running?
