[Yaffs] Problems compiling YAFFS direct interface.

[Michael Erickson]

Hello all,

Just wondering if anyone has actually ever used the direct interface. I 
got the latest version out of CVS yesterday. When I try and build the 
code I get the following error:

I've searched through the code quite a bit but can't seem to come up 
with what is wrong with the structure. It seems as though my development 
system's header files are over-riding something.

Is YAFFS direct compile-able on a Linux box?
Can I _not_ include standard headers?

The documentation on the direct interface says the following:

[snip]
Compilation Configuration

Configuration is done in four places:
	* yaffscfg.c: OS specific functions
	* yaffscfg.h: Preferably only change YAFFSFS_N_HANDLES, the
	  number of files that can be simultaneously opened.
	* yportenv.h: Preferably do not change this.
	* Compile options. The valid compile options for the YAFFS
	  direct interface are:
	* CONFIG_YAFFS_DIRECT must be enabled to use the direct
	  interface.
	* CONFIG_YAFFS_SHORT_NAMES_IN_RAM define to enable short name
	  caching. This is suggested in cases unless RAM is very
	  limited.
[/snip]

I checked yaffscfg.c and it appeared to have reasonably stubbed-out 
functions which should allow the system to compile.

Everything else listed there says to not change it. So, I guess I'm 
stuck for the moment.

Any input would be greatly appreciated.

Thanks,
	--mike
