I have partially resolved the issue. I deleted all boost libraries and headers from my machine and clean re-compiled and installed 1.43.<div><br></div><div>I can now compile with unordered_map successfully. I suspect the compiler was using one version of the libraries and a different version of the headers.</div>
<div><br></div><div>Unfortunately, I still cannot #include &lt;boost/numeric/ublas/matrix_sparse.hpp&gt; while also including rice/Data_Type and rice/Constructor. The #undefs Steven recommended don&#39;t appear to make a difference.</div>
<div><br></div><div>I&#39;ve included the current code below. It compiles perfectly if I comment the first line. If I replace the Data_Type.hpp header with a different rice header, it still doesn&#39;t work -- I&#39;ve tried Class.hpp, String.hpp, Object.hpp, and Constructor.hpp.</div>
<div><br></div><div>FYI, here&#39;s the address for rice: <a href="http://rice.rubyforge.org/main.html">http://rice.rubyforge.org/main.html</a></div><meta http-equiv="content-type" content="text/html; charset=utf-8"><div>
