[提问]QT连接BOOST库问题？ [复制链接]

error: undefined reference to `boost::system::generic_category()'
error: undefined reference to `boost::system::system_category()'
装BOOST库添加进去后总报以上错误，这个该怎么解决呢

添加的库文件是这样的
win32:CONFIG(release, debug|release): LIBS += -L$$PWD/lib/ -llibboost_system-mgw48-mt-1_55.dll
INCLUDEPATH += $$PWD
DEPENDPATH += $$PWD

win32:CONFIG(release, debug|release): LIBS += -L$$PWD/lib/ -llibboost_filesystem-mgw48-mt-1_55.dll
INCLUDEPATH += $$PWD
DEPENDPATH += $$PWD

在boost/system/error_code.hpp 头文件里加了一句#<define>BOOST_ERROR_CODE_HEADER_ONLY后来又报multiple definitions of "boost::system::throws"，有人知道怎么解决吗？
