将静态库与 gnu g++ 链接：没有这样的文件或目录，Makefile

Question

我正在使用 makefile 来编译我的简单应用程序。这是：

CURRDIR = `basename $(PWD)`
MAINAPP = main
SECTION = section
POINT = point
FIGURE = figure
CIRCLE = circle
TRIANGLE = triangle
RECTANGLE = rectangle

MAINSRC = $(MAINAPP).cpp
SECTIONSRC = $(SECTION).cpp
CIRCLESRC = $(CIRCLE).cpp
TRIANGLESRC = $(TRIANGLE).cpp
RECTANGLESRC = $(RECTANGLE).cpp

MAINKOM = $(MAINAPP).o
SECTIONKOM = $(SECTION).o
CIRCLEKOM = $(CIRCLE).o
TRIANGLEKOM = $(TRIANGLE).o
RECTANGLEKOM = $(RECTANGLE).o

SECTIONHEADER = $(SECTION).h
POINTHEADER = $(POINT).h
CIRCLEHEADER = $(CIRCLE).h
TRIANGLEHEADER = $(TRIANGLE).h
RECTANGLEHEADER = $(RECTANGLE).h
FIGUREHEADER = $(FIGURE).h

MAINEXE = $(MAINAPP).x

COMPILER = g++
COMPILERCOPTIONS = -Wall -c

LINKER = $(COMPILER)
LINOP = -Wall
BIBSTAT = libfigures.a

BIBKOM = section.o triangle.o rectangle.o circle.o
AR = ar
AROP = rv 

$(BIBSTAT): $(BIBKOM)
    $(AR) $(AROP) $@ $?

all: $(MAINEXE)

$(SECTIONKOM): $(SECTIONSRC)
    $(COMPILER) $(COMPILERCOPTIONS) $(SECTIONSRC)
$(CIRCLEKOM): $(CIRCLESRC)
    $(COMPILER) $(COMPILERCOPTIONS) $(CIRCLESRC)
$(TRIANGLEKOM): $(TRIANGLESRC)
    $(COMPILER) $(COMPILERCOPTIONS) $(TRIANGLESRC)
$(RECTANGLEKOM): $(RECTANGLESRC)
    $(COMPILER) $(COMPILERCOPTIONS) $(RECTANGLESRC)

$(MAINKOM): $(MAINSRC) $(SECTIONHEADER) $(POINTHEADER) $(CIRCLEHEADER) $(TRIANGLEHEADER) $(RECTANGLEHEADER) $(FIGUREHEADER)
    $(COMPILER) $(COMPILERCOPTIONS) $(MAINSRC)

$(MAINEXE): $(MAINKOM) $(SECTIONKOM) $(CIRCLEKOM) $(TRIANGLEKOM) $(RECTANGLEKOM) $(BIBSTAT)
    $(LINKER) -o $@ $(LINOP) $^ $(MAINEXE) $(MAINKOM) $(SECTIONKOM) $(CIRCLEKOM) $(TRIANGLEKOM) $(RECTANGLEKOM) 

run: $(MAINEXE)
    ./$(MAINEXE) 

clean:
    rm -f a.out *~ *.o *.x

tar: clean
    (cd ..; tar cvzf $(CURRDIR).tar.gz $(CURRDIR); ls -altr)

但是，我似乎在链接静态库时遇到了问题。这是我执行 make all:

后的输出

$ make all
g++ -Wall -c main.cpp
g++ -Wall -c section.cpp
g++ -Wall -c circle.cpp
g++ -Wall -c triangle.cpp
g++ -Wall -c rectangle.cpp
ar  rv  libfigures.a section.o triangle.o rectangle.o circle.o
ar: creating libfigures.a
a - section.o
a - triangle.o
a - rectangle.o
a - circle.o
g++ -o main.x -Wall main.o section.o circle.o triangle.o rectangle.o libfigures.a main.x main.o section.o circle.o triangle.o rectangle.o 
g++: error: main.x: No such file or directory 1
make: *** [main.x] Error 1

知道我在这个 makefile 上做错了什么吗？

Answer 1

你的最终命令是

g++ -o main.x -Wall main.o section.o circle.o triangle.o rectangle.o \
       libfigures.a main.x main.o section.o circle.o triangle.o \
       rectangle.o

这里发生的事情太多了：您 (1) 将每个对象重复两次 (2) 使用这两个对象和从它们构建的库 (3) 使用输入文件列表中的输出文件。

应该是

g++ -o main.x main.o libfigures.a

您可能需要像这样修改 makefile 规则：

$(MAINEXE): $(MAINKOM) $(BIBSTAT)
    $(LINKER) -o $@ $^
