https://svn.boost.org/trac10/ticket/11116 <p> I am running the regression tests on the develop branch with Oracle Solaris Studio12.4 on Solaris 11.2 OS. </p> <p> Tests for asio fail as follows: ../boost/system/config.hpp", line 34: Error: #error Must not define both BOOST_SYSTEM_DYN_LINK and BOOST_SYSTEM_STATIC_LINK. </p> <p> I looked at the developer issues on <a href="http://www.boost.org/development/tests/develop/developer/issues.html">http://www.boost.org/development/tests/develop/developer/issues.html</a> </p> <p> and see that asio tests fail similarly. </p> <p> See discussion on <a class="ext-link" href="http://lists.boost.org/Archives/boost/2015/03/220407.php"><span class="icon">​</span>http://lists.boost.org/Archives/boost/2015/03/220407.php</a> </p> <p> For possible solution: Removing the following line &lt;library&gt;/boost/system<em>boost_system </em></p> <p> from libs/asio/test/Jamfile.v2 </p> <p> seems to resolve the issue. </p> en-us /htdocs/site/boost.png https://svn.boost.org/trac10/ticket/11116 Trac 1.4.3
