clamav compile error - missing zlib

Hi all.

This is something I think could be quite critical as more malicious programs are targeted at Linux. I handle alot of peoples data as i work on their machines and or networks, so I thought it was quite important to be able to scan their file systems using the supplied clamav, but this is only useful if it is up to date.

I was trying to upgrade clamav which was going ahead quite well until the compilation process stopped at...
* configure: error: Please install zlib and zlib-devel packages

I have tried to find these packages without success.

Has anybody else had this issue?

clamav compile error - missing zlib

Hi Mike,
I had this ages ago I searched for zlib in synaptic went down list and installed both zlib and zlib-dev also updated clamav and klamav within synaptic then clamav was okay.Dont know if you have tried this. Clamav now runs okay.

I wish it were that easy

zlib and zlib-dev are not in the repos and I don't know where to find them.

I believe these packages should be included with the Mepis cd at the very least because without them, clamav is no good for the latest viruses after 30-60 days.

I deal with viruses every day being a computer technician, and while we don't use clamav as our chosen package, the fact it is supplied with SM without the necessary tools to keep it up to date carries with it a level of concern for the masses.

Searching helps...

http://packages.debian.org/stable/libs/zlibc

You may also consider your options here:

Clamav is not something that is directly useful to the Linux user, as it is directed more toward scanning for windoze exploit threats.

I support a host of clients who have opted to stick with windoze, and I no longer offer them anything in the way of AV scanning beyond what they can purchase at retail; the rationale being that they should bear the full TCO of their inferior choices.

Eventually, the high cost of maintaining windoze-based systems, has forced many of these clients to seriously consider the advantages that Linux has to offer at the desktop/workstation level.

It at that point that my Linux conversion/adoption rate spiked. I feel that I have done them more long-term good in this way, rather than being an enabler of their windoze addiction.

Consider it as an option for you.

Linux adoption

Although it is easy to identify with your perspectives on Linux and Windows, as a professional, I myself feel that customer needs and optimizing I.T. to better suit the company's core competencies *always* trump any personal views on software or the people who are using it.

If my company followed your reasoning and intentionally caused a customer to pay more for security, software, or services than was necessary, we would be out of business in a week... especially with the hypercompetition in our industry these days.

Outside the company, if I were to do such a thing, I couldn't help but wonder what is going to happen when said customer discovers I purposely snubbed a low-cost or free alternative; one that could have saved them money, just because I don't like Windows.

How will you respond when the customer asks, "So if you knew this was free, runs on Windows, and could have saved us money, why didn't you tell us about it?"

Because you don't like Windows. Hm.

If I were the customer, I would be extremely disappointed to say the least; and I could absolutely guarantee that I would never call you again.

Beyond that, not all Linux distributions are free of charge - and although it has taken some time for Linux to move in closer to the desktop while managing the border and IDS, it is this shift in O/S paradigms that is working wonders for our business. We have customers chomping at the bit to purchase IBM's WebSphere CommerceXpress and load it onto their brand new SLES or RHEL clusters. My company has made more margin on SLES in Q1+Q2 2006 than in the past 3 fiscal years combined!

One last thing I'd like to point out is that these booming Linux sales are the direct result of the corporation's IT needs. Just like eBay needed it's V3 architecture and opted for J2EEE instead of .NET back in the day, these customers compared and contrasted a number of systems options and Linux/OSS came out ahead. I honestly believe that this will be the case more and more as we move forward.

So that's my $0.02 - - if that much Smiling

Look for these packages:

zlib1g
zlib1g-dev

Nix Hard's picture

SM6, ClamAV update - added zlib1g, zlib1g-dev

SM6, ClamAV update - added zlib1g, zlib1g-dev as ralvy said.
plus need headers to upgrade KlamAV side if you go that far. I didn't.

Thanks to all that responded.

I was asking this question more for the sake of others than myself. I mostly use nod32 on all my machines, but this is a paid product which may not be suitable for most linux users as it does not have a gui.

I do think clamav is a great product, and I agree, the reason for having it is more for the protection of others when data is being passed through from one machine to another, but I have seen a recent linux user account exhibit random internet behaviour similar to an infected windows machine when wine is installed and the kde prefs set to open all .exe files with wine for that user.

A word of caution to those that want their windows progs to run in linux???
