[Bdi4emc-help] quickstep

   hi paul,
   i had trouble compiling in the drivers/vital directory, but i felt i
   could safely comment this out and so i did.
   when i did "make modules_install"  at one point Makefile tried to
   include /Makefile.inc, i presume because somehow $(PWD) became
   undefined.  i hard coded the path into Makefile and with these changes
   it looked like everything went ok but with so many warnings concerning
   deprecated char** strings, i could easily missed an error or two.
   perhaps the compile did go successfully since often Make stops with an
   actual error.
   when i tried to run my old script from my bdi-4.51 system "x3.run",
   these are the results.   i presume you expected some problems along
   these lines.
inivar = plat/nonrealtime/bin/inivar
INIFILE = x3.ini

x3.ini was not changed.

these appear to be emc related lines from dmesg
