How did you install clamav?

Can you please provide the output from clamconf -n? It may help us reproduce the issue so we can understand what is going wrong.

[JTMosaic]

Thanks for taking a look at this!

Installed:

wget https://www.clamav.net/downloads/production/clamav-0.104.2.linux.x86_64.rpm --user-agent="Mozilla/5.0"
sudo rpm -ivh clamav-0.104.2.linux.x86_64.rpm

Found the reason.
stracing the process shows, that the terminfo is being searched in

/root/.mussels/install/host-static/share/terminfo
It actually looks for "xterm-256color" at /root/.mussels/install/host-static/share/terminfo/x/xterm-256color
I guess it's a relic from the build environment.

This makes clamd run for me:

mkdirhier /root/.mussels/install/host-static/share/terminfo/x
cp /lib/terminfo/x/xterm-256color /root/.mussels/install/host-static/share/terminfo/x/xterm-256color

[JTMosaic]

Thanks for the research and possible workaround. We are on Amazon Linux so this worked for me:

As root:

mkdir -p ~/.mussels/install/host-static/share
ln -s /usr/share/terminfo ~/.mussels/install/host-static/share/terminfo

So now the question is: Will this be, or has this been fixed?

[val-ms]

Nice find @hildeb. That is indeed a relic from the build environment. It seems ncurses installs some terminfo databases under <prefix>/share/terminfo and then looks in that path at runtime to load them.

One kind of lousy option would be to change the ./configure line for building ncurses to this:

          ./configure --prefix={install} --with-default-terminfo-dir=/usr/share --disable-db-install

It may solve the issue for one of you, but unfortunately not for both.

Alternatively, we could abandon using a static lib for this dependency and link with libncurses.so instead. Either way would require you to have ncurses installed for that terminfo stuff... so... that'd at least make it easier for distros where it installs under /lib instead of /usr/share... This would probably be the easiest solution.

I suppose that ideally we'd have the .deb and .rpm packages install the terminfo database along with clamav, and install under /usr/local/share/terminfo. But I'm not sure how to do that.

[ragusaa]

I believe this has been resolved. Going to close this issue, but please re-open if you are still having problems.

[JTMosaic]

This has not been fixed. It is still an issue in ClamAV 1.3.0. The fix above, to create a .mussels folder and symlink terminfo, is still necessary to use clamdtop

[ragusaa]

My apologies, I'll re-open.

[prestonvanloon]

Still an issue in 1.4.1. The workaround above did not work for me.

Edit: The following workaround worked for me.

ln -s /usr/share/terminfo ~/.terminfo
