makefile not changing input filename-CodePudding

I am trying to make a C program and have the following makefile:

CC=clang
CFLAGS=-std=c99 -Wall -pedantic
LDFLAGS=
LDLIBS=
OUT=nes_slop
SRC_DIR=src/
OBJ_DIR=obj/
SRCS=$(wildcard $(SRC_DIR)*.c)
OBJS=$(addprefix $(OBJ_DIR),$(notdir $(SRCS:.c=.o)))
MAKE=make
CLEAR=TRUE

all: clean $(OUT)

clean:
    rm -i $(OUT) $(OBJS) -f

$(OUT): $(OBJS)
    $(CC) $(CFLAGS) $(OBJS) -o $(OUT)

$(OBJS): $(SRCS)
    $(CC) -c $(CFLAGS) $(LDLIBS) $< -o $@

It was all well and good until I had more than 1 .c file:

clang -c -std=c99 -Wall -pedantic -lncurses  src/gamestate.c -o obj/gamestate.o
clang -c -std=c99 -Wall -pedantic -lncurses  src/gamestate.c -o obj/main.o

so, somehow the source file is not being updated, it's always gamestate.c... what's wrong with my makefile? any help is appreciated, thank you

CodePudding user response：

In short, your rule should look something like this:

$(OBJS): %.o: %.c
    $(CC) -c $(CFLAGS) $(LDLIBS) $< -o $@

You may also want to read this for how to generate automatic dependencies (so if you change a header file, your c files will automatically regenerate as needed) There's a TL;DR section at the top of that page, if you're not interested in the details.
