If you’ve just built and installed the new version 0.94 of ClamAV (because it reminded you that your current version was out of date), and you’re using the experimental features, it exposes a rather dumb bug that results in these messages in your freshclam log:
@4000000048be74fd0687f57c Software version from DNS: 0.94
@4000000048be74fd0688245c WARNING: Your ClamAV installation is OUTDATED!
@4000000048be74fd06883014 WARNING: Local version: 0.94-exp Recommended version: 0.94
Apparently ClamAV’s version comparison is not terribly clever, and the ‘new feature’ of marking experimental versions with ‘-exp’ has tripped it up. I’m sure there are multiple workarounds, but I changed this in shared/misc.c:
/*#define EXP_VER “-exp”*/
as the EXP_VER string is what gets appended to the version number (apparently only for display purposes, but it does the trick). I then rebuilt it and now my log says:
@4000000048be848926da098c Software version from DNS: 0.94
Yay – no error!
