2.4.18-rmk7 + CVS jffs2 ld error (zlib)

[Michael Palme <m.palme@goepel.com>]

hello...

i know this was discussed some times ago in the list but i'read the old 
threads but no success.
i have kernel 2.4.18-rmk7 and i would like to build it with jffs2 from 
latest CVS. i have patched /patches/patchin.sh with patch from Henrik 
Nordstrom posted today, and applied on the kernel sources. on building i 
get lots of errors at the final linking:

so i grepped around in the list archive and found a possible solution to 
remove compr_zlib.o from COMPR_OBJS in jffs2/Makefile. Now after 
rebuilding i get:

i tried also to apply the patches from 
ftp://ftp.kernel.org/pub/linux/kernel/people/dwmw2/shared-zlib on top of 
my kernel but this is something tricky...

so i would like to know if someone has a fast workaround ???

thanks in advance ... Michael Palme
