Compiling Errors of map_funcs.c

Compiling Errors of map_funcs.c

[Chen Zhigao]

Folks,

I try to enable support MTD device under MontaVista 3.1 for our Intel 
IXP425 demo board. However, I got some errors when compiling the MTD 
driver of the intel-ixdp4xx-arm_xscale_be Linux Support Package. I would 
appreciate it if you could give me some pointer. Below is what I did.

#make ixdp425_config		// use default settings for IXP425
#make dep
#make zImage

I add "CONFIG_MTD_COMPLEX_MAPPINGS=y" into .config to enable the 
definition of the "read16", "copy_from" and etc. fields. And "make dep; 
make zImage" again.

xscale_be-gcc -mbig-endian -D__KERNEL__

-Wstrict-prototypes -Wno-trigraphs -Os -fno-strict-aliasing -fno-common

map_funcs.c
map_funcs.c:81: error: parse error before "do"
map_funcs.c:95: error: `simple_map_init' undeclared here (not in a function)
map_funcs.c:95: error: initializer element is not constant
map_funcs.c:95: error: (near initialization for

I can not figure out these errors, particularly line 81. Any comment and 
suggestion will be highly appreciated.

You need to contact your MontaVista support channel for your problem. 
Those are old file versions of a kernel no longer supported here at 
linux-mtd, and no one here knows how to translate those line numbers to 
some previous version of the source code.  If a supported IXP425 LSP 
cannot compile its supported mtd mapping driver then it's a bug in that 
product.  I can give you a hint that your ixp425.c is apparently older 
than the rest of the mtd code and needs various mods to match the rest 
of the code.
