[uClibc] Postfix dns_query problem

[Reet]

Hi everyone,

I got a problem compiling postfix in an actual uclibc buildroot.
I've seen that uwoody includes postfix-1.1.11-0, so it must be
compilable somehow. The question is : how :)

After applying the following patch:

I do:

# make

and I still get the error:

collect2: ld returned 1 exit status
make: *** [smtpd] Error 1
make: *** [update] Error 1

what's wrong exatly? do I have to apply another patch? change postfix
release ? (I tried also 1.1.12, 1.1.13, 2.0..no success) or do I have to
install another lib? I searched all over the net but didn't find a
solution for this...as I said, I'm using the actual uclibc buildroot.

Any help is appreciated!
Thank you very much
