Question

我的makefile存在问题。

我开发这个挑战，以及这家公司给我的.dylib文件。

所以当我创建我的Makefile时它是这样的

CC := g++

SRCDIR := src
BUILDDIR := build
TARGET := bin/challenge

SRCEXT := cpp
SOURCES := $(shell find $(SRCDIR) -type f -name *.$(SRCEXT))
OBJECTS := $(patsubst $(SRCDIR)/%,$(BUILDDIR)/%,$(SOURCES:.$(SRCEXT)=.o))
CFLAGS := -g # -Wall
LIB := -L lib -ldesafio 
INC := -I include

$(TARGET): $(OBJECTS)
    @echo " $(CC) $^ -o $(TARGET) $(LIB)"; $(CC) $^ -o $(TARGET) $(LIB)

$(BUILDDIR)/%.o: $(SRCDIR)/%.$(SRCEXT)
    @mkdir -p $(BUILDDIR)
    @echo " $(CC) $(CFLAGS) $(INC) -c -o $@ $<"; $(CC) $(CFLAGS) $(INC) -c -o $@ $<

clean:
    @echo " $(RM) -r $(BUILDDIR) $(TARGET)"; $(RM) -r $(BUILDDIR) $(TARGET)

run:
    bin/challenge

.PHONY: clean

我的结构也是正确的我将这个.dylib文件放到lib /（lib / libdesafio.dylib）

中

但是当我编译时我有此错误消息：

g++ build/main.o -o bin/runner -L lib -ldesafio 
Undefined symbols for architecture x86_64:
  "pm_register_callback(void (*)(int, unsigned char*, unsigned int))", referenced from:
      _main in main.o
  "pm_exec(int, unsigned char*, unsigned int)", referenced from:
      _main in main.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [bin/runner] Error 1

任何人都可以帮助我吗？
