推荐答案

在尝试将编译行嵌入到Makefile中之前，请确保您了解如何在命令行中进行操作，更重要的是，请确保它可以工作: /p>

Before trying to embed the compilation line into the Makefile, make sure you understand how to do it the command line, and more important, make sure it works:

g++ hello.cpp -o hello -I/usr/include/allegro5 -L/usr/lib -lallegro

然后，一个简单的Makefile即可编译 hello.cpp 可能是:

Then, a simple Makefile to compile hello.cpp could be:

CXX=g++
CFLAGS=
LDFLAGS=-L/usr/lib -lallegro
INCLUDE=-I. -I/usr/include/allegro5

OBJS=hello.o
OUT=hello

all: hello_rule

clean:
        rm -rf *.o hello

hello_rule: $(OBJS)
        $(CXX) $(OBJS) -o $(OUT) $(INCLUDE) $(CFLAGS) $(LDFLAGS)
