glibc isn't designed for that kind of mixing-and-matching of pieces. If name resolving is an issue, you'd probably be better off either fixing the configuration on the remote system, or linking against another resolver (like c-ares), which can be done statically if necessary. But, C-ares uses some of the same configuration files (/etc/resolv.conf) so if that's the source of the problem on that other machine, that won't help. >>> Dan ------------------------------------------------------------------- List admin: http://cool.haxx.se/list/listinfo/curl-library Etiquette: http://curl.haxx.se/mail/etiquette.html
