hello everyone
 
I have created a UBI layer on top of mtd and create a volumes in
2.6.26-rc5-01191-g23baa5b-dirty.
and when i met such error when i modprobe ubifs:
 
FATAL: Error inserting ubifs
(/lib/mdules/2.6.26-rc5-01191-g23baa5b-dirty/kernel/fs/ubifs/ubifs.ko):
Unknown symbol in module, or unknown parameter (see dmesg)
 
and in the /var/log/message: 
kernel: UBIFS error (pid 4687): compr_init: cannot inittialize
compressor zlib, error -2
 
I've try to install zlib module,but I only found a similar module named
zlib_deflate 
which is useless for the problem. Maybe seting CONFIG_UBIFS_FS_ZLIB = n
can solve this problem.
But are there some ways else and more advisable?
I need you help, thands in advance.
 
xxc.
