Hi List I face an ugly linker error in my really simple program using boost 1.32 on Linux SUSE9.3 and KDevelop the line that causes the linker error is: boost::archive::text_oarchive oa(cout); error is: cpptest.o(.gnu.linkonce.t._ZN5boost7archive18text_oarchive_implINS0_13text_oarchiveEED2Ev+0x51):/usr/local/include/boost/archive/text_oarchive.hpp:97: undefined reference to `boost::archive::basic_text_oprimitive<_STL::basic_ostream<char, _STL::char_traits<char> > >::~basic_text_oprimitive I am linking against libboost_serialization-gcc.a using "-lboost_serialization-gcc" switch in KDevelop automake manager. Am I linking right? Do I miss something? I realy have tried a lot of settings, allways with the same result. Can anyone help? Thanks.
