Hi neks,
during genmap execution i have this output:

done:    0.0%
  done:    1.0%
  done:    2.0%
  done:    3.0%
  done:    4.0%

  done:   24.0%
  done:   25.0%

i have copied only till 25%, but sometime i have "not connected  x x x x 
", can someone tell me what does it mean? I read relative genmap.f file, 
but i didn't undesrtand.
However at least it complete the command and i have the final .map file 
but i have errors during compilation, but i don't know if they aere 
related to these ones errors or they are memory issues.
