hello
I am trying to run dhcp server under uclibc environment, the package dhcp merges successfully but when I try to start the service ( /etc/init.d/dhcp start ) it tells me that the shared library libnss_dns.so can not be loaded. I investigate the mater and find that the following shared library can not be built : ( libnss_dns, libresolv.so, libc.so, and ld.so ) please tell me what to do to get these shared library into my system
best regards

Those should be uclibc libs.. You don't have uclibc installed on your
target.

That is completely impossible without more information. If you can
provide more information about the failed build maybe we can help.

I merged uclibc but I think that certain flags should be in my USE flag . would you please tell me what flags should be enabled
best regards

As said earlier, you should send details on all the steps you are
doing.. I assume your cross compiling?
read again
http://www.gentoo.org/proj/en/base/embedded/handbook/
5-Â* mkdir -p usr/portage
6- Â* mount --bind /usr/portage Â*Â* /root/uclibc/build/usr/portage
7-Â*Â* mount –bind /dev /root/uclibc/build/dev
8-Â* mount -t proc proc /root/uclibc/build/proc
9-Â*Â* chroot /root/uclibc/build /bin/bash
10- Â* env-update && source /etc/profile
11-Â* in the make.conf I added the following variables
Â*Â*Â*
FEATURES="ccache buildpkg"
USE="minimal"
PKGDIR="${PORTDIR}/packages/uclibc"
The above steps were done for preparing the uclibc build environment knowing that the stage I have used was uclibc stage3
then I have unmasked some packages that will be used in building my system ( tinygentoo) that will be installed in a compact flash
the steps then are as follows:
1- Â* mkdir /tinygentoo
2- ROOT=/tinygentoo USE=symlink emerge -avk =sys-apps/baselayout-2.0.0 uclibc busybox
then i did all the required symbolic links to busybox and all preparations including the proc and /etc/fstab and then compiled the kernel and made the initramfs , the system in the compact flash work successfully and then I have added many packages like iptables, python and twisted web server and all have worked successfully. the problem arises when i installed dhcp, it can not work neither in the build environment nor in the tinygentoo knowing that my USE flag when I merged uclibc was ( USE="minimal -build -debug -hardened (-iconv) -ipv6 (-nls) -pregen -saveconfig -uclibc-compat -userlocales -wordexp )
Thanks very much for reading and replying

Do you need the DHCP server or client?
Either way, you may want to look into udhcp, which may now actually
be included in busybox. And another DHCP client is dhcpcd, it's what
I like to use.

So, its an one liner. Suppose your text is inside file 'datext'.

the uClibc package itself provides the C library, resolver, etc... if you
dont have that package installed, then you wont have any system libraries.
the libnss_dns.so is a glibc-specific library. either dhcp itself was not
compiled properly, or it refers directly to the library. most likely the
issue is the former rather than the latter.
run `emerge dhcp` *inside of the chroot* and make sure that it works there
before trying to transition over to the /tinygentoo. also, the /tinygentoo
step has to be performed inside of the chroot, not outside of it.
