I am trying to compile this example http://www.boost.org/doc/libs/1_42_0/doc/html/boost_propertytree/tutorial.ht... and I am getting the error "/usr/local/boost_1_47_0/boost/property_tree/detail/ptree_implementation.hpp:795:54: error: request for member ‘put_value’ in ‘tr’, which is of non-class type ‘bool’" in this line: BOOST_FOREACH(const std::string &name, m_modules){ pt.put("debug.modules.module", name, true); }
My full error message is:
<snip>
I'd guess that this is a breaking change between 1.42 and 1.47. I checked the documentation for 1.47 and the example has definitely changed.
Steven, a breaking change in what? Which example has changed? Where? Is this a problem in BOOST_FOREACH or in property_tree?
It has to be in property_tree. The error is inside property_tree, and m_modules is just a std::set<std::string>.
Basically, the bool-parameter version of put() no longer exists; there are now put() and add(). I can't remember what the boolean meant exactly, so I don't know which one is right for this situation. The error happens because the third parameter is unconditionally interpreted as a translator object, which is why the function attempts to call put_value() on it. Sebastian
