title: Building OpenSSH on Cygwin
body: <p>I'm trying to build OpenSSH 5.1 on Cygwin.  I'm using the following configure command:</p>
  
  <pre><code>./configure --prefix=/usr --sysconfdir=/etc --libexecdir='${sbindir}' \
  --localstatedir=/var --datadir='${prefix}/share' --mandir='${datadir}/man' \
  --infodir='${datadir}/info'
  </code></pre>
  
  <p>The configure command runs OK, but when I try to make I get this error:</p>
  
  <pre><code>gcc -g -O2 -Wall -Wpointer-arith -Wuninitialized -Wsign-compare -Wformat-security -fno-builtin-memset  -I. -I.. -I. -
  ..  -DHAVE_CONFIG_H -c bsd-arc4random.c
  In file included from ../openbsd-compat/openbsd-compat.h:45,
                   from ../includes.h:169,
                   from bsd-arc4random.c:17:

  ../openbsd-compat/getrrsetbyname.h:59:20: resolv.h: No such file or directory
  </code></pre>
  
  <p>I'm a bit stuck.  Anyone got any ideas.</p>
