Question

首先，我使用命令构建boost： sudo ./bjam variant = release link = static threading = multi runtime-link = static -j4 install

我将Makefile复制到目录日志示例 /家庭/ fof606 /工作/ boost_1_57_0 /库/日志/示例/琐碎

Makefile的内容是

DEFS = '-DMSG="Hello world!\n"'
INCS = 
LIBS = -lboost_log_setup \
       -lboost_log \
       -lboost_date_time \
       -lboost_filesystem \
       -lboost_system \
       -lboost_thread

CFLAGS   = $(DEFS) $(INCS) -O2 -Wall
CXXFLAGS = $(DEFS) $(INCS) -O2 -Wall
LDFLAGS  = $(LIBS) -s

CFLAGS_DEBUG   = $(DEFS) $(INCS) -g -Wall
CXXFLAGS_DEBUG = $(DEFS) $(INCS) -g -Wall
LDFLAGS_DEBUG  = $(LIBS)

SRCS = $(wildcard *.c *.cc *.cpp *.cxx)
EXT  = $(firstword $(suffix $(SRCS)))
OBJS = $(SRCS:$(EXT)=.o)
DEPS = $(SRCS:$(EXT)=.d)
BIN  = main

PREFIX=/usr/local

ifeq ($(EXT), .c)
LANG = C
else
LANG = CXX
endif

.PHONY: all debug strip install uninstall clean

all: $(BIN)

debug: CFLAGS   = $(CFLAGS_DEBUG)
debug: CXXFLAGS = $(CXXFLAGS_DEBUG)
debug: LDFLAGS  = $(LDFLAGS_DEBUG)
debug: all

strip: all
    strip $(BIN)

$(BIN): $(OBJS)
ifeq ($(LANG), C)
    $(CC) $(LDFLAGS) -o $@ $^
else
    $(CXX) $(LDFLAGS) -o $@ $^
endif

%.d: %$(EXT)
ifeq ($(LANG), C)
    $(CC) -MM -MP -MT $(patsubst %.d,%.o,$@) -MT $@ $< >$@
else
    $(CXX) -MM -MP -MT $(patsubst %.d,%.o,$@) -MT $@ $< >$@
endif

install: all
    install $(BIN) $(DESTDIR)$(PREFIX)/bin

uninstall:
    rm -f $(DESTDIR)$(PREFIX)/bin/$(BIN)

clean:
    rm -f $(BIN) *.o *.d

-include $(DEPS)

然后我运行make。链接错误显示（所有错误信息的一部分）：

非常感谢！

检查/usr/local/lib中构建库的名称，因为boost构建框架adds name suffixes用于不同的构建配置。您必须相应地更新makefile（-lboost_log和其他）中的库引用。

当我使用boost log时，静态链接提升日志失败
