如何在 1.54 版本上使用来自 Boost 的日志库？（我正在使用 QtCreator 并已成功使用 boost/filesystem）
我读到日志库现在是 Boost 的一部分，但我不能让它在 MacO 上工作：
我的.pro文件：
#-------------------------------------------------
#
# Project created by QtCreator 2013-10-30T14:34:26
#
#-------------------------------------------------
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = Fottopic
TEMPLATE = app
SOURCES += main.cpp\
mainwindow.cpp \
configwindow.cpp \
windowmanager.cpp
HEADERS += mainwindow.h \
configwindow.h \
windowmanager.h
INCLUDEPATH += /usr/local/Cellar/boost/1.54.0/include
QMAKE_LIBDIR += /usr/local/Cellar/boost/1.54.0/lib
LIBS += -lboost_system\
-lboost_filesystem\
-lboost_log\
-lboost_log_setup
构建时输出：
