Summary: Compile Busybox without MMU failed.
Description:
Compilation failed when building Busybox for Generic ARM (no MMU) target.
You need to disable "start-stop-daemon", "System Logging Utilities", and
"udhcp Server/Client" in order to compile successfully.
If rebuild buildroot for Generic ARM (with MMU), compiling Busybox will be
successful and without this issue.

What version of uClibc are you building against, and could you post your
.config to the mailing list?

Your libc isn't providing daemonize(), and those things (quite
understandably) want it. This is a toolchain issue, not a busybox issue.
man 3 daemonize

not really
would also say it's a toolchain/kernel problem that fork() isnt available
on uClinux ?

It's fixed with the attached patch "patch_busybox_daemon",
for i386 and ARM uClinux.
Other architectures are easy to add, and I'll do so if someone asks
(but you can probably do it yourself).
Because uClinux kernel doesn't implement fork(), uClibc doesn't
implement daemon() on those targets. However daemon() can be
implemented using clone() and an assembly stub.
Only use this patch with supported MMUless uClinux targets.
It has the wrong behaviour otherwise.
It would be great if someone includes this patch in the Busybox
source tree and adds an Autoconf test to decide when to use it,
which is when there isn't a working fork().
Enjoy, --Jamie

We will take care of this in bb_xdaemon for the BB_NOMMU case.
E.g.:
#if !BB_NOMMU /* normal case, we have fork */
#define bb_xdaemon(chd,clo,str) common_xdaemon(chd,clo)
#else
#define bb_xdaemon(chd,clo,str) vfork_daemon_rexec(chd,clo,str)
#endif
If by then we still have not exported argv and argc, we'll have to also
pass these in -- for the case we end up calling vfork_daemon_rexec().

Appears to be fixed in svn. start_stop_daemon works for me on NOMMU.
