DNS_SERVERS On Pycurl

I'm trying to use pycurl to download test page using different resolvers. >>> pycurl.version 'PycURL/7.19.3.1 libcurl/7.35.0 WinSSL' I tried: c = pycurl.Curl() c.setopt(c

Solution 1:

From http://curl.haxx.se/libcurl/c/libcurl-errors.html

Error 4

CURLE_NOT_BUILT_IN (4)

A requested feature, protocol or option was not found built-in in this libcurl due to a build-time decision. This means that a feature or option was not enabled or explicitly disabled when libcurl was built and in order to get it to function you have to get a rebuilt libcurl.

My guess is that the underlying libcurl c library was not compiled with the c-ares library included.

To resolve this it may require compiling libcurl yourself and enabling c-ares in the configure script.

urllib2 might be an option see Tell urllib2 to use custom DNS
