The first one is for Visual Studio's swprintf_s function and the second one should be for the rest, but this function is declared differently in MinGW and also takes an integer as second argument. The correct interface is declared in MinGW's libintl.h header on line 419 as following: </p> <div class="wiki-code"><div class="code"><pre><span class="k">extern</span> <span class="kt">int</span> <span class="nf">swprintf</span> <span class="p">(</span><span class="kt">wchar_t</span> <span class="o">*</span><span class="p">,</span> <span class="kt">size_t</span><span class="p">,</span> <span class="k">const</span> <span class="kt">wchar_t</span> <span class="o">*</span><span class="p">,</span> <span class="p">...);</span> </pre></div></div><p> That deceleration is also what the C99 standard declares: <a class="ext-link" href="http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1124.pdf"><span class="icon">​</span>§7.24.2.3 (p. 362)</a> </p> <p> A fix would either involve to change the #else statement completely to add a second parameter as with swprintf_s or another check for MinGW. Probably the better solution would be to completely eliminate the swprintf function and make use of streams. </p> <p> If tested the version 1.49, 1.50 and 1.51 and for all, my application fails to build, simply by including the ASIO header. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/7373 Trac 1.4.3 viboes Tue, 18 Sep 2012 16:57:02 GMT https://svn.boost.org/trac10/ticket/7373#comment:1 https://svn.boost.org/trac10/ticket/7373#comment:1 <ul> <li><strong>owner</strong> set to <span class="trac-author">chris_kohlhoff</span> </li> <li><strong>component</strong> <span class="trac-field-old">None</span> → <span class="trac-field-new">asio</span> </li> </ul> Ticket chris_kohlhoff Sun, 30 Dec 2012 23:17:22 GMT https://svn.boost.org/trac10/ticket/7373#comment:2 https://svn.boost.org/trac10/ticket/7373#comment:2 <ul> <li><strong>status</strong> <span class="trac-field-old">new</span> → <span class="trac-field-new">closed</span> </li> <li><strong>resolution</strong> → <span class="trac-field-new">fixed</span> </li> </ul> <p> (In <a class="changeset" href="https://svn.boost.org/trac10/changeset/82290" title="Merge from trunk: * Fix some 64-to-32-bit conversion warnings.
