Requirements</A>

The following elements are requires to compile ClamAV:
<UL>
<LI>zlib and zlib-devel packages
</LI>
<LI>gcc compiler suite (both 2.9x and 3.x are supported)
</LI>
</UL>
The following packages are optional but <B>highly recommended</B>:
<UL>
<LI>bzip2 and bzip2-devel library
</LI>
<LI>GNU MP 3
<BR>
It's very important to install the GMP package because it allows
freshclam to verify the digital signature of the virus database.
If freshclam was compiled without GMP support it will display
"SECURITY WARNING: NO SUPPORT FOR DIGITAL SIGNATURES" on every
update. You can download GNU MP at <TT><A NAME="tex2html16"

<BR>
A note for Solaris users: you should set the <I>ABI</I> system
variable to 32 (e.g. <code>setenv ABI 32</code>) before running the
GMP's configure script <A NAME="tex2html17"
