I'm using uclibc 0.9.28 and either gcc 4.1 or 3.4.6 (same result). Might it
be worth a shot to drop the reinitialization?

due to a bug in libpthread with uclibc. After the main-process forked a
new process and died, I had to re-initialize libpthread from the child to
make mutexes work…
I'm not sure how to fix this without reordering lots of code in owlib
(and use pthread-function first time after deamon is called). This should
fix the problem, but I never tried to do those changes before. The quick fix
was to re-initialize pthread and it worked for all platforms I used at that
time.

__pthread_initial_thread_bos = NULL;
__pthread_initialize();
It's strange that you don't have PTHREAD_MUTEX_ADAPTIVE_NP defined in
pthread.h. It's defined in all uclibc versions I have seen.
Which uclibc-version do you have?

It looks like there are three files it's used in: ow_cache.c, ow_locks.c,
and ow_tree.c. The first two can be disabled with config options.
When I attempted to build with gcc-mipsel-linux-uclibc 4.1 I got the
following error
owlib.c: In function 'LibStart':
owlib.c:215: error: '__pthread_initial_thread_bos' undeclared (first use

Ah. Okay. How tough is it to build owfs for dd-wrt? Is it simply a matter
of taking the source distro and compiling with mipsel-uclibc?

tsearch is the binary tree search that is part of glibc and some
implementations of uClibc. It may not have been included in the dd-wrt
version of uClibc. It could be an optional part of owlib, like some of the
semaphore and other code.
Does that give you a place to look?

I've gotten as far as the previous poster with install OWFS on DD-
WRT: when I try to start the daemon I get a "can't resolve symbol
'tsearch' "-error. I tried installing uclibc from http://
downloads.openwrt.org/whiterussian/packages/ and reordering
LD_LIBRARY_PATH to load that libc, but then I just got a segfault.
Any ideas how to proceed?
