Hi,

Luis is correct. I included the gcrypt and it works fine for me as well.

Thanks for the help.
Raja.

Hi,

Tried it on:

Version 0.99.7 (SVN Rev 22353)

Compiled with GTK+ 2.10.13, with GLib 2.12.12, with libpcap 0.9.5, with 
libz 1.2.3.3, with libpcre 6.7, with Net-SNMP 5.2.3, with ADNS, without 
Lua, with GnuTLS 1.6.3, with Gcrypt 1.2.4, with MIT Kerberos, with 
PortAudio PortAudio V19-devel, without AirPcap.

Running on Linux 2.6.21-2-k7, with libpcap version 0.9.5.

Built using gcc 4.1.3 20070629 (prerelease) (Debian 4.1.2-13).

No problems.

Thanx,
Jaap
