这是我的目录的样子:
/project
makefile
/ceda_lib
makefile
files....
/general
makefile
files....
/CLI
makefile
files....
/objects
files.o
生成文件(主要):
1 #start other makefiles
2
3
4 o= ./objects
5 DEPS= Affine.hpp CEDA.hpp generalParameters.hpp generalFunctions.hpp
6 OBJ= $o/main.o $o/Affine.o $o/generalFunctions.o
7 CC=g++
8 CFLAGS= -Wall -g -I.
9 export CC
10 export CFLAGS
11 export DEPS
12
13 all:
14 ▸---+$(MAKE) -C general
15 ▸---+$(MAKE) -C ceda_lib
16 ▸---+$(MAKE) -C CLI
17
18 run: $(OBJ) $(DEPS)
19 ▸---$(CC) -o $@ $^
其他生成文件如下所示:(update2)
1 include ../makefile.variables
2
3 OBJ = main.o
4 all: $(OBJ)
5
6 $(OBJ): %.o: %.cpp $(DEPS)
7 ▸---$(CC) -o ../objects/$@ -c $< $(CFLAGS)
我想要做的是编译 3 个目录中的所有代码并将所有对象存储在 /object 目录中。然后将从 $DEPS 和 /object 目录的内容创建一个可执行文件。
这个makefile不能令人遗憾地工作。您能否找出我做错了什么,您能否建议我改进代码的方法。(我对makefile很陌生)。
这也是我尝试制作项目时的输出:(Update2)
