Hi Eliot,

I wonder how the Pharo builds handle those. Because these have always been enabled there.
Also, these primitives are from the original SqueakVM branch (interpreter), so there should be problems as well if the primitives are missing.

Hi Levente,
   no need for any action on your part.  I see that the Serial Port primitives are essentially unimplemented on Mac OS so it is trivial to provide null implementations for the "ByName" ones.

Last time I talked with the people using the SerialPort plugin they said on Mac they use the linux plugin since the Mac plugin is not implemented, the linux plugin is, and the linux plugin works on all unix systems including Mac.

      Hi Levente,
    when I try and build on Mac OS X I get this:

  "_serialPortOpenByName", referenced from:
      _primitiveSerialPortOpenByName in SerialPlugin.lib(SerialPlugin.o)
  "_serialPortReadIntoByName", referenced from:
      _primitiveSerialPortReadByName in SerialPlugin.lib(SerialPlugin.o)
  "_serialPortWriteFromByName", referenced from:
      _primitiveSerialPortWriteByName in SerialPlugin.lib(SerialPlugin.o)

The implementations are missing in both platforms/Mac OS/plugins/SerialPlugin/sqMacSerialPort.c and platforms/iOS/plugins/SerialPlugin/sqMacSerialPort.c.  They are there in
platforms/unix/plugins/SerialPlugin/sqUnixSerial.c and platforms/win32/plugins/SerialPlugin/sqWin32SerialPort.c.

:-(
