Shown below are the problems I encountered when attempting to build the latest MTD tree for uclinux 2.0.38. For the moment I have suspended efforts to get this working under 2.0.38 and would be very interested if someone could provide a MTD version or patch that will work with that kernel. If so, please let me know. Thank you! :-) Steve Kranz skranz@ridgerun.com --------------------------- My choosen config settings: --------------------------- CONFIG_MTD=y CONFIG_MTD_DEBUG=y CONFIG_MTD_DEBUG_VERBOSE=3 CONFIG_MTD_CHAR=y CONFIG_NFTL=y CONFIG_NFTL_RW=y CONFIG_MTD_NAND=y ---------------- Missing Headers: ---------------- MTD depends on these headers which don't exist within the uclinux tree. linux/slab.h linux/spinlock.h linux/kmod.h --------------- Other Problems: --------------- include/linux/mtd/map.h line 65, generates error: "field `list' has incomplete type" Attempts to compile the MTD statements __MOD_INC_USE_COUNT() and __MOD_DEC_USE_COUNT() found in various locations with the MTD tree generate these compile errors: "structure has no member named `uc'" "structure has no member named `flags'" -------------- Version Notes: -------------- I downloaded via cvs.infradead.org on July 9, 2001. I placed it into my 2.0.38 uclinux tree and then applied the MTD supplied patch mtd-uClinux-2.0.38.1pre7.patch. ----------- David Woodhouse wrote: > skranz@ridgerun.com said: > > 1.
