https://svn.boost.org/trac10/ticket/12375 <p> This patch makes it possible to use this header in programs built using the FASTbuild (<a class="ext-link" href="http://fastbuild.org"><span class="icon">​</span>http://fastbuild.org</a>) and more precisely its caching feature. </p> <p> Considering the following code: </p> <p> clmacro.cpp: </p> <pre class="wiki">int main(void) { #define funny_type(x) x funny_type(int)const a = 2; // cl.exe -P clmacro.cpp -&gt; `intconst a` } </pre><p> On MSVC (Visual Studio 2013) Microsoft (R) C/C++ Optimizing Compiler Version 18.00.40629 for x86 Copyright (C) Microsoft Corporation. All rights reserved. </p> <p> This compiles correctly by default with <code>CL.exe</code> </p> <pre class="wiki">Cl.exe clmacro.cpp </pre><p> However when using the <code>/P</code> compilation flag to obtain the pre-processed source, then trying to compile the resulting file this will fail because const gets stitched to the other symbol before compilation. </p> <p> See: </p> <pre class="wiki">cl.exe -P -Ficlmacro.i.cpp clmacro.cpp &amp;&amp; cl.exe clmacro.i.cpp </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/12375 Trac 1.4.3 anonymous Wed, 03 Aug 2016 10:52:20 GMT https://svn.boost.org/trac10/ticket/12375 https://svn.boost.org/trac10/ticket/12375 <ul> <li><strong>attachment</strong> → <span class="trac-field-new">0001-Allow-compilation-on-MSVC-with-P.patch</span> </li> </ul> <p> Patch against boost::icl </p> Ticket anonymous Wed, 03 Aug 2016 10:53:43 GMT
