从命令行构建Eclipse Makefile项目

我创建了Eclipse Makefile C++项目,目的是在没有Eclipse的情况下构建项目。但我在终端运行make时出错:

Makefile:15: *** Build mode  not supported by this Makefile.  Stop.

如何解决这个问题?如果我不能用make构建Eclipse Makefile,为什么我需要它?

Makefile内容:

PROJECT_ROOT = $(dir $(abspath $(lastword $(MAKEFILE_LIST))))

OBJS = boiler.o

ifeq ($(BUILD_MODE),debug)
    CFLAGS += -g
else ifeq ($(BUILD_MODE),profile)
    CFLAGS += -O2
else ifeq ($(BUILD_MODE),run)
    CFLAGS += -O2
else ifeq ($(BUILD_MODE),linuxtools)
    CFLAGS += -g -pg -fprofile-arcs -ftest-coverage
    LDFLAGS += -pg -fprofile-arcs -ftest-coverage
else
    $(error Build mode $(BUILD_MODE) not supported by this Makefile)
endif

all:    boiler

boiler: $(OBJS)
    $(CXX) $(LDFLAGS) -o $@ $^

%.o:    $(PROJECT_ROOT)%.cpp
    $(CXX) -c $(CFLAGS) $(CXXFLAGS) $(CPPFLAGS) -o $@ $<

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

clean:
    rm -fr boiler $(OBJS)
