compiling on an older system (Centos 6)

[Zakaria]

Try this
./configure  --prefix=/usr --with-pam --with-selinux 
--with-privsep-path=/var/lib/sshd/ --sysconfdir=/etc/ssh 
--with-ssl-dir=/usr/local/openssl

Or this
PKG_CONFIG_PATH='/usr/local/lib/pkgconfig:/usr/local/openssl/lib64/pkgconfig' 
./configure  --prefix=/usr --with-pam --with-selinux 
--with-privsep-path=/var/lib/sshd/ --sysconfdir=/etc/ssh 
--with-ssl-dir=/usr/local

It might fix it. I use it on centOS 7 and it works just fine.

Zak.
