[clamav-users] Problem with ClamAV 0.98.4 - HAVP won't load CVD files

[Shawn Webb]

Hey Paul,

The reason for that is likely due to my usage of ctors and dtors with
0.98.3. In that version, I had added a ctors entry in libclamav to call
cl_initialize_crypto and a dtors entry to call cl_cleanup_crypto. It turns
out that operating systems like AIX, HPUX, and Solaris 10 don't support
ctors/dtors. In order to provide support for those OSs, I opted to remove
the ctors/dtors entries and call cl_initialize_crypto directly in the
applications that we distribute that consume libclamav (clamscan, clamd,
clamdscan, freshclam, etc.) That means that we're no longer calling
cl_initialize_crypto in the background and third-party applications will
need to call cl_initialize_crypto themselves. But that may or may not
change with the discussion on Monday.

Thanks,

Shawn
