baudcheck bad substitution #85

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
Substitution in baudcheck.tmp.sh fails.

It looks like the baudcheck shell script gets generated without specifying 
exactly which shell it should use.  I heat that recent Ubuntu uses "dash" 
instead of bash, and that probably doesn't work.
I'll try to fix this (keeping track of which shell specifications will work on 
which OSes is ... obnoxious), but in the meantime you can try this workaround:
  make SHELL=/bin/bash lilypad

As a workaround, I've made the makefile ignore errors in the "baudcheck" step:
