unresolved symbols in kernel (MTD_CVS and linux 2.4.19pre1)

[olivier.eribon at free.fr]

I'm trying to compile the latest MTD_CVS (/home/oeribon/MTD_CVS/mtd) with my
2.4.19pre1 Linux kernel in order to use JFFS2 on Nand flash.
I've symlinked this files in the kernel :

./drivers/mtd                 -> /home/oeribon/MTD_CVS/mtd/drivers/mtd/
./fs/jffs2                    -> /home/oeribon/MTD_CVS/mtd/fs/jffs2/
./fs/ffs2                     -> /home/oeribon/MTD_CVS/mtd/fs/ffs2/
./include/linux/mtd           -> /home/oeribon/MTD_CVS/mtd/include/linux/mtd
./include/linux/jffs.h        -> /home/oeribon/MTD_CVS/mtd/include/linux/jffs.h
./include/linux/jffs2.h       -> /home/oeribon/MTD_CVS/mtd/include/linux/jffs2.h
./include/linux/jffs2_fs_i.h  ->
/home/oeribon/MTD_CVS/mtd/include/linux/jffs2_fs_i.h
./include/linux/zlib.h        -> /home/oeribon/MTD_CVS/mtd/include/linux/zlib.h
./include/linux/zutil.h       -> /home/oeribon/MTD_CVS/mtd/include/linux/zutil.h
./include/linux/zconf.h       -> /home/oeribon/MTD_CVS/mtd/include/linux/zconf.h
./include/linux/jffs2_fs_sb.h ->
/home/oeribon/MTD_CVS/mtd/include/linux/jffs2_fs_sb.h
./include/linux/crc32.h       -> /home/oeribon/MTD_CVS/mtd/fs/jffs2/crc32.h
./kernel/mapped.c             -> /home/oeribon/MTD_CVS/mtd/kernel/mapped.c
./kernel/mixmem.c             -> /home/oeribon/MTD_CVS/mtd/kernel/mixmem.c
./lib/zlib_deflate            -> /home/oeribon/MTD_CVS/mtd/lib/zlib_deflate/
./lib/zlib_inflate            -> /home/oeribon/MTD_CVS/mtd/lib/zlib_inflate/
./util                        -> /home/oeribon/MTD_CVS/mtd/util/

I have the same problem (Andrew Dixon & Chris Wilson (unresolved symbols in
kernel Apr. 2002))

Could you give me some information about tree structure integration of MTD_CVS
and linux kernel.
How can i compile MTD_CVS and a kernel (as 2.4.19) with JFFS2 without any error?

With Regards,
Thanks in advance
