我的MakeFile找不到我的标头目录 [英] My MakeFile can't find my header directory

问题描述

这是我的Makefile:

This is my Makefile :

NAME    = pong

SRCS    = src/main.cpp

OBJS    = $(SRCS:.cpp=.o)

CFLAGS  += -lsfml-graphics -lsfml-window -lsfml-system -I include/

all: $(NAME)

$(NAME): $(OBJS)
    g++ -o $(NAME) $(SRCS) $(CFLAGS)

clean:
    rm -f $(OBJS)

fclean: clean
    rm -f $(NAME)

re: fclean all

.PHONY: all clean fclean re

当我执行 make 时，它告诉我main.ccp中包含的标头不存在.

When I do make, it tells me that the header I include in my main.ccp does not exist.

#include "prototypes.hpp"

这是我的项目组织:

.
├── a.out
├── include
│   └── prototypes.hpp
├── Makefile
├── src
│   └── main.cpp
└── test

最奇怪的是，当我这样做时

And the weirdest thing is that this work when I do

g++ -o test src/main.cpp  -lsfml-graphics -lsfml-window -lsfml-system  -I include/

知道为什么吗?

推荐答案

遵循您的规则

$(NAME): $(OBJS)

对 $(OBJS)的依赖将首先运行 make 隐式℅.o:℅.cpp规则，该规则反过来使用 $ CXXFLAGS ，因此看不到 -I 选项.

the dependency on $(OBJS) will run makes implicit ℅.o : ℅.cpp rule first, which in turn uses $CXXFLAGS and thus doesn't see the -I option.

在编写规则时，只需忽略对 $(OBJS)的依赖.

As your rule is written, just omit the dependency on $(OBJS).
