将静态库与gnu g 链接:没有这样的文件或目录，makefile

Linking static library with gnu g++: No such file or directory, Makefile

本文关键字：文件 makefile 静态 gnu 链接      更新时间：2023-10-16

我正在使用makefile来编译我的简单应用程序。在这里是：

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有问题。这是执行make all之后的输出：

$ 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

有什么想法我对此做错了什么？

您的最终命令是

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

这里发生了太多事情：您（1）重复每个对象两次（2）使用对象和由它们构建的库（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 $@ $^
