Boost Xcode C++ command line Undefined symbols for architecture x86_64 -

i have gotten boost work in test application following instructions here. need create command-line application generate licenses. i've inherited code , uses boost. think i've set correctly when try build receive undefined symbols architecture x86_64 error using boost.

i created command-line application:

i added path boost:

i tried change c++ standard library compiler:

here code referencing boost library:

#include <boost/date_time/posix_time/posix_time_io.hpp>  namespace bg = boost::gregorian; namespace bp = boost::posix_time; 

here errors:

has gotten command-line application using boost build? if yes, can please help?

thank you.

the problem may caused 2 different problems:

1. you haven't linked library propertly:

in "build phases" tab, in "link binary libaries" add: libboost_program_options.a

2. another problem how have compiled , linked boost library when installed library.

if want use libstdc++ should build boost this:

./bootstrap.sh ./b2 cxxflags="-stdlib=libstdc++" linkflags="-stdlib=libstdc++" ./b2 install --prefix=yourinstallationdirectory 

and use libstdc++ in xcode.
