Re: Newbie: Can't compile

Hi Peter,

Some others have encountered the same sort of errors building ClamAV with newer versions of gcc/g++.  We are aware of the issue and a fix will be on the way.

I am trying to compile the sourcecode of clamav 0.99.3.
I use "gcc (Ubuntu 6.3.0-12ubuntu2) 6.3.0 20170406" on Kubuntu 17.04 64bit.

I get the following output when entering "make":

So what can I do to get clamav sourcecode compiled?
