Unresolved Symbol load_nls

[David Feest]

Hello,

for a couple of days now I've been trying to integrate dos, umsdos and vfat-support into my kernel, either built-in or as modules. I failed.

Using make menuconfig I first tried to build in everything:

(*) DOS FAT fs support
(*) MSDOS fs support
(*) UMSDOS: [...]
(*) VFAT (Windows 95) fs support

Under Native Language Support I added the Codepages 437, 850, NLS ISO 8859-1 and NLS ISO 8859-15, NLS UTF8, also built in.

Trying to mount a floppy I got the message:
mount: unknown filesystem type `vfat`


I then tried every combination of including the above as modules and as built-in. Generally, when trying to load one of the features as modules I get the message:
unresolved symbol load_nls
unresolved symbol load_nls_default
unresolved symbol unload_nls
unresolved symbol utf8_wcstombs
Indeed: I don't know how to install these as modules.

Did I forget something crucial? Any help is appreciated!

Thanks,

David

All those symbols are exported by fs/nls/nls_base.c which corresponds to CONFIG_NLS. It should get pulled in automatically by the *fat modules. Can you please post the output of
