title: building log4cxx in vs 2010 c++
body: <p>This is driving me crazy, I'm trying to building the log4cxx library in order to use in a c++ project I've been using. I'm on a win7 host running VS2010 express c++ edition. I've followed the directions per the log4cxx directions (   ) including downloading apr
  and apr-util and motifying the .hw files, but I unfortunately, when ever I try to load the log4cxx.dsw solution and convert it to the current VS, I receive an error trying to build apr.apr/dsw and a bunch of other dependent .dsw files. Any suggestions?</p>
  
  <p>Specifically, what I am seeing is:</p>
  
  <pre><code>The Project file 'C:\...projects\apr-util\xml\expat\lib\xml.dsp' cannot be loaded. Do you want to remove the unloadable project from the solution?
  </code></pre>
  
  <p>I see this for a bunch of other .dsp files. </p>
  
  <p>then in the output box in VC:</p>
  
  <pre><code>C:\Users\x\Documents\Visual Studio 2010\Projects\apr\apr.dsp : error  : Project upgrade failed.
  
  C:\Users\x\Documents\Visual Studio 2010\Projects\apr-util\xml\expat\lib\xml.dsp : error  : Project upgrade failed.
  
  C:\Users\x\Documents\Visual Studio 2010\Projects\apr-util\aprutil.dsp : error  : Project upgrade failed.
  
  C:\Users\x\Documents\Visual Studio 2010\Projects\apache-log4cxx-0.10.0\projects\log4cxx.dsp : error  : Project upgrade failed.
  </code></pre>
  
  <p>Thanks</p>
  
  <p><strong>The files are in the correct path.</strong></p>
