I was searching for the same thing (compiling ClamAV 0.88.6 on OpenBSD 3.8) when I came across this page before yours:

http://www.idapps.com/zager/openbsd-notes.html

He uses environment variables which seems cleaner than modifying the configure script.

Here’s the configure string that I used:

env CFLAGS="-I/usr/local/include" LDFLAGS="-L/usr/local/lib -lpthread" \ ./configure –sysconfdir=/etc –with-user=_clamav –with-group=_clamav –disable-cr –disable-threads

I’m using csh instead of the default ksh thus the difference in setting the environment variables. I didn’t find the "–disable-threads" option in the configure script (there is a "–disable-pthreads" option), but it still seems to work. If you use "–sysconfdir=/etc", then you don’t have to do the soft-linking.

Hope this helps someone. Thanks for your posting as well. I’m glad I’m not the only one trying to compile ClamAV on older versions of OpenBSD as well.

When compiling ClamAV 0.88.7 (and perhaps higher), do not use “-disable-pthreads” or “-disable-threads” in your configure statement, otherwise clamd and clamdscan will not get compiled. (I found out the hard way.)

My new configure string is:

env CFLAGS=”-I/usr/local/include” LDFLAGS=”-L/usr/local/lib -lpthread” \
./configure –sysconfdir=/etc –with-dbdir=/var/db/clamav \
–with-user=_clamav –with-group=_clamav –disable-cr
