windows - QT and Boost : Cannot find -llibboost_filesystem -


i work (and cannot other version of qt) :

  • qt creator 2.4.1 , qt 4.8.4 (with mingw compiler)
  • boost 1.52

to build boost :

  • i first added "c:/qt/qtcreator-2.4.1/mingw/bin" path variable
  • then opened command prompt
  • went "c:/boost_1_52"
  • typed "bootstrap.bat mingw"
  • and "b2 toolset=gcc build-type=complete stage" (this took long time (about 2h))

i use qt creator boost library come against difficulties. project simple, it's basic qt code :

qcoreapplication a(argc, argv)  return a.exec()

i added includes :

#include <boost/thread.hpp> #include <boost/property_tree/json_parser.hpp>  #include <boost/asio.hpp> #include <boost/timer.hpp>

in .pro file have added :

defines += boost_all_use_lib  includepath += c:/boost_1_52 libs += -lc:/boost_1_52/stage/lib \ -lboost_system-mgw48-mt-1_52 \ -lboost_thread-mgw48-mt-1-52 \ -lboost_timer-mgw48-mt-1_52  #"libboost_system..." needs library libs += -lc:/windows_sdk/lib \ -lws2_32

when build projects have 2 kinds of 'undefined reference to' :

  • some 'thread' in : 

    undefined reference `boost::thread::thread()' undefined reference `boost::thread::joinable() const'

  • some looks :

    undefined reference `boost::system::generic_category()' undefined reference `boost::system::system_category()'

thank in advance help.

try this.

libs += "-lc:/boost_1_57_0/libs/" \

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
