debugging - 使看不到带有％标记的规则

Question

我正在尝试将调试目标添加到all-dbg之类的项目中，但是收到错误消息:

    $ make all-dbg
    make: *** No rule to make target 'tted.o-dbg', needed by 'tted-dbg'.  Stop.

这是Makefile:

    TARGET=tted
    CC=gcc
    CFLAGS=-Wall -std=c99
    CFLAGS-dbg=-g
    LDFLAGS=-lncurses

    all: $(TARGET)

    all-dbg: $(TARGET)-dbg

    SOURCES=$(wildcard *.c)
    HEADERS=$(wildcard *.h)
    OBJECTS=$(patsubst %.c, %.o, $(SOURCES))
    OBJECTS-dbg=$(patsubst %.c, %.o-dbg, $(SOURCES))
    PCHEADERS=$(HEADERS:=.gch)

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

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

    %.h.gch: %.h
            $(CC) $(CFLAGS) $<

    $(TARGET): $(PCHEADERS) $(OBJECTS)
            $(CC) $(OBJECTS) $(LDFLAGS) -o $@

    $(TARGET)-dbg: $(PCHEADERS) $(OBJECTS-dbg)
            $(CC) $(OBJECTS-dbg) $(LDFLAGS) -o $@

    clean:
            -rm -f *.o
            -rm -f *.o-dbg
            -rm -f *.h.gch
            -rm -f $(TARGET)
            -rm -f $(TARGET)-dbg

有什么建议？

您缺少%.o-dbg: %c中的点。它可能应该改为读取%.o-dbg: %.c。
