c++ - gcc 4.8 linker error during linking boost thread library -

-

i have compiled boost library myself using g++4.8 compilation finished success. located in ~/bin/boost. after compilation files located in /users/$(user)/bin/boost/stage/lib/

below necessary make parts:

cc=g++-4.8 ld=g++-4.8  boost_lib_path=/users/$(user)/bin/boost/stage/lib/ boost_header_path=/users/$(user)/bin/boost/  lflags=-l$(boost_lib_path) -lboost_thread  release: $(obj)         $(ld) $(obj) obj/main.o $(lflags) -o $(release_name)

everything goes ok during compilation linking process fail. errors same:

ndefined symbols architecture x86_64:   "boost::system::system_category()", referenced from:       __static_initialization_and_destruction_0(int, int)

i have read : attempting use boost.filesystem doesn't seem link? c++ / boost: undefined symbols in example? , many others still did not find solution.

i have no idea problem, have change order of linking, try link directly thread library still same result. problems occur during compilation of https://github.com/dbedla/snake-cpp11 under mac os x 10.8.4 (i have modify makefile)

i grateful suggestion how solve problem.

sorry english :(

you need add -lboost_system after had -lboost_thread.

i'm in process of developing wp8 app makes use of background location tracking abilities provided os. idea monitor users position , notify them when near types of places. so far seems work fine , when running location tracking works expect. the problem is, seems phone times out background apps after around 4 hours, stopping location tracking. i can understand why microsoft did it, preserve battery life etc. there's not point having background location tracking app has manually restarted every 4 hours! if user chooses run app , made aware of potential battery hit, surely should able run indefinitely - point of course, if system runs out of resources or similar that's fair enough. does have experience this? there must hundreds of others apps in store have run issue have thought? , presumably there must way of keeping location tracking running? i've tried periodically updating live tile (using dispatchertimer) while tracking running doesn't seem enough ke
