Hello, I think that you should supply more information. Where are those functions supposed to be defined?
> ./.libs/libmxresolv.a(mxresolver.o): In function `mx_lookup': > undefined reference to `__ns_initparse' > undefined reference to `__ns_parserr' > undefined reference to `__ns_name_uncompress' Also make sure that they are not enclosed in something like #ifdef USE_FOO ... #endif blocks you don't know about (sometimes you have to define some preprocessor symbols during compilation) Hope it helps, Matěj
