#64710: ncarg: /dev/tty: Device not configured.

 Priority:  Normal      |  Milestone:
Component:  ports       |    Version:  2.7.1
 Keywords:  arm64       |       Port:  ncarg
------------------------+----------------------
 ncarg fails to configure on arm64 systems:

 https://build.macports.org/builders/ports-
 12_arm64-builder/builds/43236/steps/install-port/logs/stdio

 The error coming from `ymake` is:

 {{{
 /dev/tty: Device not configured.
 }}}

 This happens because config/ymake contains this code:

 {{{
 case    Darwin:
         set os = $opsys

         switch ("$mach[1]")
         case    Power:
             set model   = $mach
             set arch    = $mach
             set sysincs = Darwin
             set vendor  = Apple
             breaksw
         case    i386:
         case    x86_64:
             set model   = $mach
             set arch    = $mach
             set sysincs = Darwin_Intel
             set vendor  = Apple
             breaksw
         default:
             echo "$0 : Unknown machine type" > /dev/tty
             exit 1
         endsw

         breaksw
 }}}

 As you see, there is no case for ARM systems, so it is trying to run the
 command `echo "$0 : Unknown machine type" > /dev/tty`, but this command
 fails when run under the control of MacPorts for some reason.

 I gather that ncarg is no longer being developed, so I presume the
 developers will not assist us. If you think it's easy to add arm64 support
 to ncarg, feel free to do so. Otherwise, you should mark the port as not
 supporting arm64 by adding this line:

 {{{
 supported_archs i386 ppc ppc64 x86_64
 }}}
