https://svn.boost.org/trac10/ticket/13176 <p> The compiler specific .hpp files in boost/config/ all have a fallback text that is shown as message (or error message, depending on BOOST_ASSERT_CONFIG being set or not) with the following text: </p> <pre class="wiki">"Unknown compiler version - please run the configure tests and report the results" </pre><p> We met this message recently after an update of the VS 2017 compiler from 15.2 to 15.3 (which decided to change _MSC_VER from 1910 to 1911), see <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/13167" title="#13167: Bugs: &#34;Unknown compiler version ...&#34; with 1.64 on Visual Studio 15.3 (closed: fixed)">ticket:13167</a> and given Microsofts new compiler version policy it is expected that this message will occur quite often in the future. But the request of this issue is different from <a class="closed ticket" href="https://svn.boost.org/trac10/ticket/13167" title="#13167: Bugs: &#34;Unknown compiler version ...&#34; with 1.64 on Visual Studio 15.3 (closed: fixed)">ticket:13167</a>: Please extend that text output to make clear <strong>who</strong> is complaining here, for example </p> <pre class="wiki">"boost compiler configuration: Unknown compiler version - please run the configure tests and report the results" </pre><p> I'm strongly encouraging to provide something like this text enhancement, because the text appears in between a lot of other compiler messages, so the unaware reader of the full preprocessor output cannot remotely guess at this point, where this request comes from. I'm willing to provide a concrete pull request once there is consensus about the concrete text change. Personally I'm open in regard to the details, but my suggestion would be to provide additional context information. I would guess that the minimum text change would simply be along the lines of: </p> <pre class="wiki">"Boost: Unknown compiler version - please run the configure tests and report the results" </pre> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/13176 Trac 1.4.3 John Maddock Tue, 31 Jul 2018 18:47:08 GMT https://svn.boost.org/trac10/ticket/13176#comment:1 https://svn.boost.org/trac10/ticket/13176#comment:1 <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">obsolete</span> </li> </ul> <p> This has since been changed. </p> Ticket
