Can not compile patched 2.4.20 kernel...

[Thomas Cameron]

Hello all,

	I have been trying (for a few days now) to get my kernel patched
and compiled with the latest CVS sources for jffs(2), and the MTD
devices.  The problem, however, is that I keep getting the `parse error
before "struct"` message when actually compiling the sources.

       I have searched through google for every possible combination of
header file names, structure names, etc. that I can think of, and have
had no good reference to fixing this on the x86 platform for the 2.4.20
kernel series.  I would really love to be able to use the MTD sources
instead of the M-Systems "DiskOnChip" kernel module, because of
continuing development, support, and performance enhancements.

	To let everybody know, I am not a kernel hacker.  My confidence
in my C skills is not even close to that high.  I do have a moderate
working knowledge of the language and it's structure, so I can look at
code and at least understand it.  So, I guess if I have to jam some
patches in somewhere, I would be capable, but I think my abilities would
end there.

	Below is the last line of output from my kernel build (make
bzImage).  I hope that this explains enough what files are being looked
at during the failure.  If not, please mail me personally, and I can see
what else I can find.

Have you  tried 2.4.20 without the patches? It already has DOC and jffs2
support in it.

Thomas,

Have you tried the older 4.2 DFORMAT from M-Systems? Apparently v5
DFORMAT is not compatible with the newer kernels and I had problems
getting the DOC2000 recognized under 2.4.20.
