OTHER_DUND_DIR := $(DIR_PATH)/test_file_c

LDFLAGS := #-L/opt/test/lib
LDLIBS := #-ltest_library

SRC := main.c $(OTHER_DUND_DIR)/test.c #$(wildcard /all_build/*.c)

　　TARGET := my_program

all: $(TARGET)

$(TARGET): $(OBJ)
　　$(CC) $(CFLAGS) $(LDFLAGS) $^ -o $@ $(LDLIBS)

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

clean:
# $(warning $(OBJ) $(TARGET))
　　/bin/rm -f $(OBJ) $(TARGET)

说明：/all_build/*.c 的全部c 文件需要编译，则去掉注释/all_build/*.c的 #，即

SRC := main.c $(OTHER_DUND_DIR)/test.c $(wildcard /all_build/*.c)

若存在链接的文件在其他非标准路径下，则需要手动指定，去掉-L/opt/test/lib的注释 #,即修改为

LDFLAGS := -L/opt/test/lib

指定库名字，去掉#，即为LDLIBS := -ltest_library

LDLIBS := #-ltest_library
