  First hours testing nim, I am encountering the following:

  import os, cpuinfo
  
  echo getCurrentCompilerExe()
  
  echo ("\nProcessor count ", countProcessors())
  
  stdout.writeLine "produces no output"
  Run

  : undeclared identifier: 'getCurrentCompilerExe'
  
  Warning: a [b] will be parsed as command syntax; spacing is deprecated
  Run

  Is getCurrentCompilerExe only intended for the Windows platform but not documented?

  Can the a [b] warning be improved upon?

  Which compiler did you use? Your program compiles correctly with 1.2.2 and #devel on a Linux platform.

  Note that your use of echo is incorrect. As it is written, you write a tuple which contains the string "\nProcessor count " and an int. To get what you expect, you have to write:

  echo "\nProcessor count ", countProcessors()
  Run

  or

  echo("\nProcessor count ", countProcessors())
  Run

  without a space after echo.

  getCurrentCompilerExe seems to be posix-only, see it's implementation at https://github.com/nim-lang/Nim/blob/version-1-2/lib/pure/os.nim#L2017

  What compiler version do you have? That one must be ancient, that warning message was removed back in 2017 and was gone when 0.18.0 was released.

  wow Ubuntu Bionic package manager installs nim 0.17.2 !

  Everything solved.

  What would be the reason for the following output?

  echo ("\nProcessor count ", countProcessors())
  echo 1
  echo ()
  Run

  ("\nProcessor count ", 4)
  1
  ()
  Run

  Thanks! I tripped on the Exe part...

  What would be the reason for the following output?

  you are passing tuples

  Space between function and parameters is important.

  echo ("\nProcessor count ", countProcessors())
  echo 1
  echo ()
  Run

  is same as:

  echo(("\nProcessor count ", countProcessors())
  echo(1)
  echo(())
  Run

  Just remove the space between function and parameters and you are all set.
