Need help getting JFFS2 working with kernel 2.4.19

Need help getting JFFS2 working with kernel 2.4.19

[Conn Clark]

Hello all,

	I am new here and I am having trouble getting the JFFS2 code
working/compiling with the 2.4.19 kernel . I get multiple definition
errors when the kernel is linking.

Many thanks in advance,

	Conn

	I figured it out. The jffs2 zlib was conflicting with the zlib
used bye ppp compresion. I just had to remove zlib.o from the COMPR_OBJS
definition in the Makefile.

	Sorry for the lack of details. I figured it out yesterday but
mailed this post to myself instead of the list. Sorry again.


Thanks anyways

There's a better fix in 2.4.20-pre2 and at 
ftp.kernel.org:/pub/linux/kernel/people/dwmw2/shared-zlib/

Get the latest patch (2.4.19-pre10) and it should apply to most 2.4 kernels.

I take it that this patch wasn't submitted to Marcelo or Marcelo didn't get
it integrated the final 2.4.19 then?

Is there anything else I need to do or will the patch fix everything?


Thanks

I applied the patch and now it won't compile again.

Blah Blah Blah.

I take it there are still a few more things I must do?

here is some additional info on my system.
My processor is a PPC MPC850.
My flash chip 1 intel 28F320C3B 16 bit mode

Thanks

It's in 2.4.20-pre2. We figured it was a little too intrusive to go into 
2.4.19.

Did you run 'make oldconfig'?
