I'm trying to migrate from applications from the 2008 distro branch to 2009. I need to get shadow support working.

Under the 2008 branch, all I had to do was enable busybox to use internal shadow password functions. With 2009, I get this error when building:

I found a reference to a similar problem (using libpam):

Is the only resolution to rebuild the toolchain? This may be a stupid question, but how do I build the toolchain with that uclibc option specified?

in order to get shadow.h and related support in uClibc, you'll have to rebuild the toolchain.  it may be easier to add a small stub implementation in your own shadow.h.

does USE_BB_SHADOW not work or something ?

I could swear that USE_BB_SHADOW was checked in the Kconfig menu. I rebuilt with USE_BB_SHADOW enabled (I checked the .config this time) and still get the same results.

BusyBox shouldn't be dependent on uclibc, should it?

if you dont enable the BB_SHADOW option, then busybox will of course need shadow support in the C library

as for when you have enabled that option, in this case busybox just wants it for the spwd struct definition.  you should be able to copy that from your host system shadow.h to include/libbb.h and comment out the shadow.h include.
