freshclam: create_curl_handle: Unable to bind DNS resolves to xxx.xxx.xxx.xxx. Option requires that libcurl was built with c-ares.
Having just compiled and installed on a MultiInterface server clamav-0.103.2 following the contents (if NOT using the script) of SlackBuilds.org for clamav .
The freshclam.conf.8 manpage says (to me) insert your primary exterior interface ip in the config entry , "LocalIPAddress" , So I did .
When running freshclam (see below(*1)) , curl reports the message saying that libcurl needs c-ares (ie: libc-ares) be complied in , in order to use the "LocalIPAddress" functionality .
Fyi , Leaving "LocalIPAddress" empty allows freshclam to run just fine . As my system is multiInterfaced tho Not multirouted at the moment but will be , Thus my concern .
Tho for those running on true MultiRouted servers are going have a problem when they HAVE to use the "LocalIPAddress" .
How & Who should be contacted to have this library be compiled into curl ?
(*2) Below MAY show that curl is not compiled with libc-ares .
Tho ...
Code:
# nm /usr/lib64/libcurl.so.4.7.0
nm: /usr/lib64/libcurl.so.4.7.0: no symbols"

Hello ALL , Thank You . Whoever picked up my concern and passed it onto the appropriate maintainer :-) .
Code:
Fri Apr 9 20:21:07 UTC 2021
...
n/c-ares-1.17.1-x86_64-1.txz: Added.
Adding this since curl can make use of it, and some programs expect this
functionality.
n/curl-7.76.0-x86_64-2.txz: Rebuilt.
Recompiled to link with c-ares-1.17.1. Thanks to babydr.
...
Tnx Agn , JimL

Thank You all , the Local-Address capability functions well for me .
