I get an error when trying to build a kernel (1.0) . I added 

options		FIFO
options		SYSVMSG, SYSVSEM, SYSVSHM
options		SHMMAXPGS=1024		# 1024 pages is the default

to my config file.

vfs_conf.o: Undefined symbol `_ffs_fifoop_opv_desc' referenced from data segment
vfs_conf.o: Undefined symbol `_fifo_nfsv2nodeop_opv_desc' referenced from data segment
*** Error code 1 (ignored)
size: netbsd: No such file or directory
*** Error code 1


I'm probably doing something wrong, but I haven't a clue about
what it might be.....


Thanks for any info.
