error adding new drivers to an exist bsp

[sun yongbing]

hi,all
  
  i want to add a device driver for my bsp and works that have been done 
are :
  
  1.  i create a subdir named 'fb' under my bsp 
dir(c/src/lib/libbsp/m68k/mcf5307). 
  2.  In the subdir i write the source file fb.c and makefile.am (copied 
from console.am, just modified "console" to "framebuffer" ).
  3.  i modified my bsp's configure.ac by adding 'fb/Makefile' to the 
makefile list.
  4.  i modified my bsp's makefile.am by adding 'fb' to the subdir list.
  5.  i also modified wrapup/Makefile.am by adding the fb.pel to build lib.

then in my bsp dir i run '../../../../../../bootstrap -c', it is ok. But 
when i run '../../../../../../bootstrap',error occurs and error 
information:
