System: NetBSD aire.ncl.ac.uk 1.4 NetBSD 1.4 (AIRE) #1: Tue Jun 22 16:34:55 BST 1999 root@aire.ncl.ac.uk:/usr/src-1.4/sys/arch/sparc/compile/AIRE sparc


>Description:
	
A kernel configured with :

  #### Bus types found on SPARC systems.

  #sbus0	at mainbus0			# sun4c
  obio0		at mainbus0			# sun4 and sun4m
  sparcvme0	at mainbus0			# sun4
  #iommu0	at mainbus0			# sun4m
  #sbus0	at iommu0			# sun4m
  #sparcvme0	at iommu0			# sun4m
  vme0		at sparcvme0			# mi VME attachment

and :

  ## Sun "cgtwo" VME color framebuffer
  cgtwo0		at vme0 addr 0x400000 irq ? vect 0xa8

  ## Sun "cgsix" accelerated color framebuffer.
  #cgsix0		at sbus? slot ? offset ?
  #cgsix*		at sbus? slot ? offset ?
  cgsix0		at obio0 addr 0xfb000000 level 4	# sun4/300 P4
  #cgsix0		at obio0 addr 0x0b000000 level 4	# sun4/100 P4

will fail to compile :

  ld -Ttext F0004000 -e start -n -X -o netbsd ${SYSTEM_OBJ} vers.o
  bwtwo.o: In function `bwtwoattach_sbus':
  bwtwo.o(.text+0x2c8): undefined reference to `sbus_establish'
  cgsix_obio.o: In function `cgsixattach':
  cgsix_obio.o(.text+0x98): undefined reference to `cgsix_sbus_ca'
  cgsix_obio.o(.text+0x9c): undefined reference to `cgsix_sbus_ca'
  *** Error code 1

  Stop.

There don't appear to be problems with bwtwo0 and cgeight0.

>How-To-Repeat:

Try to build a kernel with the above combination of options.
