2.4.18-rmk7 + CVS jffs2 ld error (zlib)

[Michael Palme]

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

Don't do that. Apply

thanks fot the answer.
but there is still one problem left:

background.c:92: warning: implicit declaration of function `set_user_nice'
fs/fs.o(.text+0x363a0): undefined reference to `set_user_nice'

the only place i've found this is <linux/mtd/compatmac.h> (link to the 
mtd-cvs):


#if LINUX_VERSION_CODE < KERNEL_VERSION(2,4,0)
         /* Is this right? */
#define set_user_nice(tsk, n) do { (tsk)->priority = 20-(n); } while(0)
#elif LINUX_VERSION_CODE < KERNEL_VERSION(2,4,18)
#define set_user_nice(tsk, n) do { (tsk)->nice = n; } while(0)
#endif

so in 2.4.18 there is nothing related....

what should i do??? (i think of #elif LINUX_VERSION_CODE < 
KERNEL_VERSION(2,4,19) )

thanks in advance ... Michael Palme

Just comment out the offending line in background.c

Is this patch suitable for 2.4.4? The compilation errror is that 
linux/completion.h couldn't be found.

Thanks,
