I am trying to use boost/property_tree/ptree.hpp in my application. All I have done so far is just add the following include statements to my program:

#include <boost/property_tree/ptree.hpp> #include <boost/property_tree/xml_parser.hpp>

After adding these lines, I compiled my modified application using g++ 4.6.3 on Ubuntu 12.04. I get the following errors: g++ -c -Wall -Werror -I../cudd-2.4.2//include/ -I /home/pramod/libraries/boost_1_50_0/ -O2 -Wno-unused-result -Wno-unused-function -c -o main.o main.cpp In file included from /home/pramod/libraries/boost_1_50_0/boost/property_tree/ptree.hpp:17:0, from main.h:10, from main.cpp:17: /home/pramod/libraries/boost_1_50_0/boost/property_tree/stream_translator.hpp: In static member function ‘static void boost::property_tree::customize_stream<Ch, Traits, bool, void>::extract(std::basic_istream<_CharT, _Traits>&, bool&)’: /home/pramod/libraries/boost_1_50_0/boost/property_tree/stream_translator.hpp:117:18: error: expected unqualified-id before ‘{’ token /home/pramod/libraries/boost_1_50_0/boost/property_tree/stream_translator.hpp:117:18: error: expected ‘)’ before ‘{’ token /home/pramod/libraries/boost_1_50_0/boost/property_tree/stream_translator.hpp: In member function ‘boost::optional<E> boost::property_tree::stream_translator<Ch, Traits, Alloc, E>::get_value(const internal_type&)’: /home/pramod/libraries/boost_1_50_0/boost/property_tree/stream_translator.hpp:191:20: error: expected unqualified-id before ‘{’ token /home/pramod/libraries/boost_1_50_0/boost/property_tree/stream_translator.hpp:191:20: error: expected ‘)’ before ‘{’ token make: *** [main.o] Error 1 When I look the lines117 and 191 in ptree.hpp, they are the following: s >> e; if(s.fail()) { // Try again in word form. and customized::extract(iss, e); if(iss.fail() || iss.bad() || iss.get() != Traits::eof()) { return boost::optional<E>(); I can't spot anything obviously wrong with either of these lines. Does anyone have any clues on what could be going wrong? Thanks! Pramod
