    copied!<p>I can't compile <code>yaml-cpp</code> in RAD Studio 2010. I have error in <code>nodeutil.h</code></p> <pre><code>template &lt;typename T, typename U&gt; struct is_same_type { enum { value = false }; }; template &lt;typename T&gt; struct is_same_type&lt;T, T&gt; { enum { value = true }; }; template &lt;typename T, bool check&gt; struct is_index_type_with_check { enum { value = false }; }; template &lt;&gt; struct is_index_type_with_check&lt;std::size_t, false&gt; { enum { value = true }; }; // line 24 #define MAKE_INDEX_TYPE(Type) \ template &lt;&gt; struct is_index_type_with_check&lt;Type, is_same_type&lt;Type, std::size_t&gt;::value&gt; { enum { value = true }; } MAKE_INDEX_TYPE(int); MAKE_INDEX_TYPE(unsigned); // line 30 MAKE_INDEX_TYPE(short); MAKE_INDEX_TYPE(unsigned short); MAKE_INDEX_TYPE(long); MAKE_INDEX_TYPE(unsigned long); #undef MAKE_INDEX_TYPE </code></pre> <p>Compiler print:</p> <p><code>[BCC32 Error] nodeutil.h(30): E2238 Multiple declaration for 'is_index_type_with_check&lt;unsigned int,0&gt;'</code></p> <p><code>[BCC32 Error] nodeutil.h(24): E2344 Earlier declaration of 'is_index_type_with_check&lt;unsigned int,0&gt;'</code></p> <p>I think that all correct - in line 24 I got </p> <p><code>is_index_type_with_check&lt;std::size_t, false&gt;</code>, </p> <p>in line 30 I got </p> <p><code>is_index_type_with_check&lt;unsigned, true&gt;</code>. </p> <p>Two different type.</p> <p>But if I change line 24 like below, RAD Studio can compile <code>yaml-cpp</code></p> <pre><code>template &lt;&gt; struct is_index_type_with_check&lt;std::size_t, true&gt; { enum { value = true }; }; // false -&gt; true </code></pre> <p>Why?! In line 24 I got </p> <p><code>is_index_type_with_check&lt;std::size_t, true&gt;</code> </p> <p>and in line 30 </p> <p><code>is_index_type_with_check&lt;unsigned, true&gt;</code></p> <p>Two identically type. But all work in RAD Studio and doesn't in MS VS 2008 Express.</p>
