Requirements</A>
</H2>
The following elements are required to compile ClamAV:
<UL>
<LI>zlib and zlib-devel packages
</LI>
<LI>gcc compiler suite (tested with 2.9x, 3.x and 4.x series)
</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
<code>freshclam</code> to verify the digital signatures of the virus
databases and scripted updates. 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

<BR>
A note for Solaris/SPARC users: you must set the <I>ABI</I> system
variable to 32 (e.g. <code>setenv ABI 32</code>) before running the
configuration script of GMP.
