I'm doing the latter.  I've diffed my uClibc config with the one for the
matching release in Buildroot and have enabled what I think is relevant
for resolver support, re: I configured uClibc with the resolver and nsl
stubs.  However, buildroot still doesn't allow me to configure connman.

I looked at connman's Config.in and it looks like this:

comment "connman needs a toolchain with resolver support"
    depends on !(BR2_UCLIBC_VERSION_SNAPSHOT ||
BR2_TOOLCHAIN_EXTERNAL_GLIBC || BR2_TOOLCHAIN_CTNG_eglibc ||
BR2_TOOLCHAIN_CTNG_eglibc

So if I'm using an external toolchain with uClibc it doesn't allow me to
configure connman, correct?  Is the uClibc resolver stub considered
unsufficient for use with connman?  Do I need to switch to glibc?

Also, it appears that BR2_TOOLCHAIN_CTNG_eglibc appears twice in that
dependency test.  Typo?

This is from the 2012.02 tarball release.  No patches.

Thanks.
