title: Apache server module installation: How do I resolve an apxs error?
body: <p>Could you explain to me the meaning and possible fix(es) of the error below?</p>
  
  <p>I am trying to install an Apache module for FTP
  <a href="http://httpd.apache.org/mod_ftp/ftp/index.html" rel="nofollow">http://httpd.apache.org/mod_ftp/ftp/index.html</a>. I am getting this error when try to build the source file using <strong>apxs</strong>:</p>
  
  <pre><code>apxs:Error: Sorry, cannot determine bootstrap symbol name.
  apxs:Error: Please specify one with option `-n'.
  </code></pre>
  
  <p>Here is the full code in context:</p>
  
  <pre><code>$ apxs -iac mod_ftp.c
  /usr/share/apr-1/build-1/libtool --silent --mode=compile gcc    -DDARWIN -
  DSIGPROCMASK_SETS_THREAD_MASK -no-cpp-precomp  -I/usr/include/apache2  -
  I/usr/include/apr-1   -I/usr/include/apr-1   -c -o mod_ftp.lo mod_ftp.c &amp;&amp; touch 
  mod_ftp.slo
  /usr/share/apr-1/build-1/libtool --silent --mode=link gcc -o mod_ftp.la  -rpath 
  /usr/libexec/apache2 -module -avoid-version    mod_ftp.lo
  apxs:Error: Sorry, cannot determine bootstrap symbol name.
  apxs:Error: Please specify one with option `-n'.
  </code></pre>
  
  <p>This is the first module I've ever attempted to Install on an Apache server, and I'm stumped. I can't seem to find an explanation of this. In particular, what is the <strong>bootstrap symbol name</strong> and how do I specify one with option -n?</p>
  
  <p>Thanks for your help!</p>
