post the actual script that you're using. we cant fix issues that we cant reproduce.

also, you've already been told what shell to use. hush is the only one supported. if you want to use any other shell, you're on your own.

Thinks too much Mike.

I get the bysybox-1.14.2 from the

https://blackfin.uclinux.org/gf/project/uclinux-dist/scmsvn/?action=browse&path=%2Ftrunk%2Fuser%2Fbusybox%2F

but unfortunately ,when i try to compile again i got those errors:

backporting to 2008R1.5 directly isnt really supported -- it did not use the kconfig system that trunk uses. if you want to use busybox-1.14.2 with 2008R1.5, you'll have to build it by hand.

Thanks Mike for your help. I tried to compile it for Blackfin using the following commands:

make xconfig

CROSS_COMPILE=bfin-uclinux- make

But I get te following error message:

CC applets/applets.o

In file included from include/busybox.h:10,

from applets/applets.c:11:

include/libbb.h:75:21: error: shadow.h: No such file or directory

Any idea on what the problem could be or is it wrong the way I'm trying to compile?

Thanks.

you didnt properly configure busybox. run menuconfig first to disable options you dont need. it'd probably be best if you simply disabled everything in there but hush and used the binary only for hush.
