[英]How do I link Allegro 5 from my Makefile?
I need to link the Allegro Game Development Library from my Makefile .我需要从我的Makefile链接 Allegro 游戏开发库。 When I do this, the compiler returns:当我这样做时,编译器返回:
Undefinied Reference < Function Name >.
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:在尝试将编译行嵌入到 Makefile 之前,请确保您了解如何在命令行中执行此操作,更重要的是,请确保它可以正常工作:
g++ hello.cpp -o hello -I/usr/include/allegro5 -L/usr/lib -lallegro
Then, a simple Makefile
to compile hello.cpp
could be:然后,一个简单的Makefile
编译hello.cpp
可以是:
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)
