I'm porting glibc 2.3.5 to a new hardware platform on linux 2.6.9, one of our requirement is to build glibc static only, I mean -disable-shared. It means only "*.a" libraries will be created. Last time I built glibc 2.2.x where I could build all libs with -disable-shared flag in configure command, this time with glibc 2.3.5 while building modules such as 'pwd', 'zic' etc it throws error messages related pthread symbols undefined. Does it mean that I cannot build pthread for static linking?

----------
Example error messages

Am using following configure flags:

--host=XXXX-linux \
--with-headers=$(KERNEL_HEADERS) \
--enable-add-ons=linuxthreads \
--enable-static-nss \
--disable-shared \
--enable-kernel=$(KERNELVERSION) --prefix= \
--without-f \
--without-tls \
--without-nptl \
--without-__thread


Appreciate any valid feedback.
Thanks,
