Can't Build New Device Driver

[Robert S. Grimes]

Oops!  I forgot the attachments!

Also, when I ran the bootstrap command, I had a few warnings:

  $ ../../../../../../bootstrap
  .
  /usr/share/aclocal/cppunit.m4:4: warning: underquoted definition of 
AM_PATH_CPPUNIT
  /usr/share/aclocal/cppunit.m4:4:   run info '(automake)Extending aclocal'
  /usr/share/aclocal/cppunit.m4:4:   or see 
http://sources.redhat.com/automake/automake.html#Extending-aclocal

I don't know if that is significant or not...

Thanks,
-Bob
