compile errors - missing .h?

compile errors - missing .h?

[Juan Gonzo]

I updated via CVS my linux source tree today.  When I compile
I get the following errors:

================

=================

I remember a while back David saying that a person might
miss updates to include/linux/jffs.h using CVS cause he 
uses a symlink farm for this file.  I suspect this is why my
compile is failing.

If this is the case, how can someone get 'jffs.h'?

Thanks,

The most reliable way to build JFFS is outside the kernel tree. Make sure
you don't have a 'jffs.h' in /usr/src/linux/include/linux.

Then go into the MTD CVS tree, in the 'fs/jffs/' directory, and type:
 make -C /usr/src/linux SUBDIRS=`pwd` modules

You may need to swap the comments on the following two lines in the
Makefile, depending on which kernel you're building against:

	#INODE_O := inode-v22.o
	INODE_O := inode-v23.o

David,

I am not sure if I followed you instructions correctly,
but I can't get the latest CVS code for JFFS to compile.

I did a complete CVS checkout of the MTD tree, and used
the 'make' command you suggested.  I still get the same
errors.  Isn't this something to do with jffs.h?  It
seems to be missing some struct elements, specifically
"delete_list" from "struct jffs_control".

Here's the results of my make:

The compiler is finding an old version of jffs.h. Did you 'cvs update' in 
or above the ~/armbuild/mtd/mtd/include/linux/ directory, or only in the 
~/armbuild/mtd/mtd/fs/jffs/ directory?

Make sure that it can find this version:
	$Id: jffs.h,v 1.11 2000/08/04 12:46:34 dwmw2 Exp $

The old version could be in ~/armbuild/linux/include/linux/jffs.h if you 
ever tried to build JFFS into the kernel.
