Makefile：`__TMC_END__'的多重定义

标签： c++ boost makefile g++

在我之前询问过的question中，我尝试将bin和obj个文件夹与我的cpp分开。我的依赖文件（main.d）将存储在obj目录中。但是，我的尝试遇到了问题。 Linker认为，某些事情没有直接联系起来：

  

/tmp/cc7WetlH.o：在函数`__static_initialization_and_destruction_0＆＃39;：

     

/usr/include/boost/system/error_code.hpp:222：未定义引用`boost :: system :: generic_category（）＆＃39; 

SOURCES := main.cpp
BINDIR:= ./bin
OBJDIR:= ./bin/obj
OBJECTS := $(OBJDIR)/$(SOURCES:.cpp=.o)
DEPFILES:= $(OBJECTS:.o=.d)

CXX := g++
CXXFLAGS := -g -Wall -Wfatal-errors -std=c++11 -MD -MP
LIBS:= -lboost_filesystem -lboost_system 


all: run

# Link the executable
run: $(OBJECTS)
    $(CXX) $(LDFLAGS) $^ -o $(BINDIR)/$@ $(LIBS)

$(OBJDIR)/%.o: %.cpp
    $(CXX) $(CXXFLAGS) -MF $(OBJDIR)/$*.d -o $@  $<

-include $(DEPFILES)

为了解决这个问题，我将链接库添加到编译器（对我来说没有意义）：

$(OBJDIR)/%.o: %.cpp
    $(CXX) $(CXXFLAGS) -MF $(OBJDIR)/$*.d -o $@  $< $(LIBS)

该对象已成功创建，但链接器认为某些事情已定义多次：

如何解决此错误？

在编译行中添加链接器参数并没有任何意义，因为你的直觉是正确的。

您的%.o规则存在的问题是您忘记包含-c标志，以告知编译器在链接之前停止。

添加，删除链接器参数，看看你的问题是否仍然存在。
