感谢您的回复。我发现这行得通——不过我不知道为什么。

all: $(OUT)

$(OBJ_DIR)/%.o: %.c
        $(CC) $(CCFLAGS) -o $@ -c $< $(INCLUDES)

$(OUT): $(OBJ)
        ar rcs $(OUT) $(OBJ)
        cp DIMEFILEAPPSAUTH.h ../include

.PHONY: clean

下面是我拥有的makefile。我不断收到错误 make:*** No rule to make target但在这种情况下看不到有什么问题。“.c”文件存在于当前目录中。我不确定为什么makefile 看不到它们——你能解释一下吗？

DimeFileAppsAuth/src> ls
db_get_DIMEFILEAPPSAUTH.c     db_reset_query_DIMEFILEAPPSAUTH.c  Makefile
db_add_DIMEFILEAPPSAUTH.c     db_print_DIMEFILEAPPSAUTH.c  db_update_DIMEFILEAPPSAUTH.c
db_delete_DIMEFILEAPPSAUTH.c  db_reset_DIMEFILEAPPSAUTH.c

运行make

DimeFileAppsAuth/src> make
make: *** No rule to make target `../obj/db_add_DIMEFILEAPPSAUTH.o', needed by `../lib/lib_dime_file_apps.a'.  Stop.

当涉及到这一行“$（OUT）：$（OBJ）”时会发生make错误。请检查目录“../obj”中是否存在名为“db_add_DIMEFILEAPPSAUTH.o”的文件
