Cloop modules Unresolved symbols [SOLVED].....

hello,

i've tried to compile many versions of cloop modules, compilation have no problem but
i've unresolved symbols :
cloop.o: cloop.o: unresolved symbol zlib_inflate_workspacesize_Rsmp_ce5ac24f
cloop.o: cloop.o: unresolved symbol zlib_inflateReset_Rsmp_ef76d642
cloop.o: cloop.o: unresolved symbol zlib_inflateEnd_Rsmp_9ef45f92
cloop.o: cloop.o: unresolved symbol zlib_inflate_Rsmp_64cf8602
cloop.o: cloop.o: unresolved symbol zlib_inflateInit__Rsmp_456e911d

I've verified my kernel (2.4.27) config :
#
# Library routines
#
CONFIG_CRC32=y
CONFIG_ZLIB_INFLATE=y
CONFIG_ZLIB_DEFLATE=y

so i don't understand....
i've tested to
mv /usr/include/linux /usr/include/linux_old
ln -s /usr/src/linux/include/linux /usr/include/linux
and verified
ln -s /usr/src/linux-2.4.27 /usr/src/linux
but i've got the same problems

if anyone have THE solution, please help and post

thx :cry:
