我使用makefile编译我的简单应用程序。这是：
project = "MyProject" AND updated > -1d AND sprint IS EMPTY
然而，似乎我在链接静态库时遇到问题。执行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)
后，这是我的输出：
make all任何想法我对这个makefile做错了什么？
答案 0 :(得分：1)
你的最后一个命令是
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
这里有太多的事情：你（1）重复每个对象两次（2）使用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 $@ $^
