Reproducible Builds about kamailio HOT 3 CLOSED

We could create something that takes a specified timestamp from somewhere else, like
a debian packaging release time. If that doesn't exist, we'll use compile-time like now.

Just brainstorming.

cc1: some warnings being treated as errors
Can we introduce a Make option to avoid this?

from kamailio.

I see the options:

• if compiled with a flag (e.g., NO_VERSION_DATE), skip adding it completely
• if compiled with VERSION_DATE=xyz and VERSION_TIME=abc, then add them instead of predefined macros
• if none of above, then compile as it is

It should cover all cases one would like to have, I think.

Pushed a patch in master allowing to disable adding time/date in version string as well as setting a particular value.
