Question

无论如何，我不再关心隐私了。如果确实有效，保留它的重点是什么？我会稍微更改文件名。这是原始代码。

CXX=g++
CXXFLAGS= -Wall
LDFLAGS=-Wno-deprecated -fPIC -pthread
DIR=Exedir/

EXOoffline=EXOdir/offline/
EXOofflinelib=utilities/misc utilities/database utilities/calib reconstruction analysis/manager analysis/jni analysis/root geant/EXOsim
LIBRARY=-lGui -L/usr/lib/root/5.09 -lMinuit -L/nfs/rabbitybunny/g/exo-software/software/hudson/builds-rhel5/build-id/1077/lib -lEXOUtilities -lEXOSim -lEXOROOT -lEXODBUtilities -lEXOAnalysisManager -lEXOAnalysisJNI -lEXOCalibUtilities -lEXOReconstruction -L/afs/rabbitybunny.edu/package/cernroot/vol35/52800svn/Linux26SL5_i386_gcc412/lib -lTreePlayer
INCLUDE=-I $(ROOTSYS)/include `root-config --glibs` -I /nfs/rabbitybunny/g/exo/software/builds/current/include
INCLUDE+=$(addprefix -I$(EXOoffline),$(EXOofflinelib))

all: run

run: main.o
        $(CXX) main.o -o $(DIR)$@ $(LIBRARY)
.cpp.o:
    $(CXX) $(CXXFLAGS) $(INCLUDE) -c -o $@ $<

#run: main.cpp
#       $(CC) $(CFLAGS) $(LDFLAGS) $(INCLUDE) $(LIBRARY) main.cpp -o $(DIR)$@

.PHONY: clean
clean:
        rm -rf *.o $(DIR)run

我得到了这个。

rabbitybunny@enigma $ make clean
rm -rf *.o Exedir/run
rabbitybunny@enigma $ make
g++ -Wall -I /afs/rabbitybunny.edu/package/cernroot/vol35/52800svn/Linux26SL5_i386_gcc412/include `root-config --glibs` -I /nfs/rabbitybunny/g/exo/software/builds/current/include -IEXOdir/offline/utilities/misc -IEXOdir/offline/utilities/database -IEXOdir/offline/utilities/calib -IEXOdir/offline/reconstruction -IEXOdir/offline/analysis/manager -IEXOdir/offline/analysis/jni -IEXOdir/offline/analysis/root -IEXOdir/offline/geant/EXOsim -c -o main.o main.cpp

感谢您的帮助，我真的很感激。（也许我应该学习使用cmake。）

Answer 1

我不知道为什么你要创建一个基本上复制现有问题的全新问题，除了示例更整洁。为什么不编辑您现有的问题？

无论如何，问题是规则.cpp.o是编译代码（将源文件.cpp转换为目标文件.o），但是你将链接器标志传递给它（-L$(LIBDIR)等）。同样，当您链接代码与run目标时，您不要将链接器标志传递给它。

通常你也 NOT 想要将-c标志放在CXXFLAGS变量中，因为通常你想在编译和链接行上使用该变量确保你的旗帜一致。

重写：

CXX = g++
CXXFLAGS = -wall
CPPFLAGS = -I$(INCDIR)

all: run
run: run.o
        $(CXX) $(CXXFLAGS) run.o -o $@ -L$(LIBDIR) -lpng
.cpp.o:
        $(CXX) $(CXXFLAGS) $(CPPFLAGS) -c -o $@ $<

Answer 2

我认为您的问题来自root-config宏中的INCLUDE命令：

INCLUDE=-I $(ROOTSYS)/include `root-config --glibs` ...

如果你运行它，它可能会列出一大堆-lXxx选项 - 编译器所说的那些选项未使用，因为你在创建目标文件时没有链接。

运行root-config --glibs并查看输出。然后找到另一个选项来生成包含选项而不是库。

Makefile，加载外部源
