[Buildroot] ARM build error with llseek.c

Thu May 15 16:41:48 PDT 2008

Thanks Chris,

Looks like the issue was with LFS not being enabled in uclibc
(CONFIG_UCLIBC_HAS_LFS) and also BusyBox not having
BR2_PACKAGE_BUSYBOX_HIDE_OTHERS selected. I did a make clean for everything
and rebuilt, and got past that error.

I am fairly certain I understand why LFS needed to be enabled, because I was
reading up on a couple threads online about llseek.c being used for large
file support in general, while lseek.c is used for small files. I want LFS
for my purposes, and it is possible that by not selecting LFS in the uclibc
menuconfig, that a specific function or variable wasn't defined correctly in
a header file used by llseek.c, and therefore it couldn't compile correctly.
This is of course my best assumption.

As for selecting BusyBox's hide others option, I am unsure as to why that
works, but found it here as a suggestion.

http://buildroot.uclibc.org/lists/buildroot/2007-June/003077.html

I hope this helps anyone in the future.
