https://svn.boost.org/trac10/ticket/13449 <p> <strong>How to reproduce:</strong> </p> <p> Build System: Ubuntu 16.04.0 LTS GCC: all </p> <p> Let's say that we have the boost sources in <code>/tmp/boost-linux/boost_1_X_X</code> </p> <p> The important thing is to have the string <code>linux</code> in the <code>boost-root</code> variable. </p> <p> <strong>Error log:</strong> </p> <pre class="wiki">python boost_mpl_preprocess.py In file included from /tmp/boost-linux/boost_1_63_0/libs/mpl/preprocessed/vector/vector40.cpp:15:0: /tmp/boost-linux/boost_1_63_0/boost/config.hpp:30:29: fatal error: /tmp/boost-1/boost_1_63_0/libs/mpl/preprocessed/include/plain/user.hpp: No such file or directory compilation terminated.
