https://svn.boost.org/trac10/ticket/9800 <p> The Windows cmd interpreter badly handles )'s in rem statements, *sometimes* (but not always) closing "if" statements they are nested within. Per docs, parens are illegal in rem commands (see technet.microsoft.com/en-us/library/bb490986.aspx). </p> <p> On my Win7 64bit box, this was causing bootstrap vc12 to go down bizarre paths. One potential fix is to escape the parens, i.e. use ^( and ^) instead of () in comments. I wish I were making this up (sigh). </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/9800 Trac 1.4.3 aoney@… Thu, 20 Mar 2014 21:01:47 GMT https://svn.boost.org/trac10/ticket/9800#comment:2 https://svn.boost.org/trac10/ticket/9800#comment:2 <ul> <li><strong>component</strong> <span class="trac-field-old">None</span> → <span class="trac-field-new">Building Boost</span> </li> </ul> Ticket Steven Watanabe Thu, 03 Apr 2014 16:11:17 GMT https://svn.boost.org/trac10/ticket/9800#comment:3 https://svn.boost.org/trac10/ticket/9800#comment:3 <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> <li><strong>description</strong> modified (<a href="/trac10/ticket/9800?action=diff&amp;version=3">diff</a>) </li> </ul> <p> Fixed in <a class="ext-link" href="http://github.com/boostorg/build/commit/23032af425c3940810d5ff22e52475a02632c998"><span class="icon">​</span>http://github.com/boostorg/build/commit/23032af425c3940810d5ff22e52475a02632c998</a> </p> Ticket
