我正在寻找一个简单的推荐最小"c++ makefile for linux,它将使用 g++ 来编译和链接单个文件和 h 文件.理想情况下,make 文件中甚至不会包含物理文件名,并且只有 .cpp 到 .o 的转换.在不深入研究 autoconf 的恐怖的情况下生成这样的 makefile 的最佳方法是什么?
I've looking to find a simple recommended "minimal" c++ makefile for linux which will use g++ to compile and link a single file and h file. Ideally the make file will not even have the physical file names in it and only have a .cpp to .o transform. What is the best way to generate such a makefile without diving into the horrors of autoconf?
当前目录包含,例如
t.cppt.h
并且我想要为此创建一个 makefile.我试过 autoconf 但它假设 .h 是 gcc 而不是 g++.是的,虽然我不是初学者,但我正在从多年前重新学习项目操作的最佳方法,因此我正在寻找自动化的方法来为小型项目创建和维护 makefile.
and I want a makefile for that to be created. I tried autoconf but its assuming .h is gcc instead of g++. Yes, while not a beginner, I am relearning from years ago best approaches to project manipulation and hence am looking for automated ways to create and maintain makefiles for small projects.
如果是单个文件,可以输入
If it is a single file, you can type
make t
它会调用
g++ t.cpp -o t
这甚至不需要目录中的 Makefile,尽管如果您有 t.cpp、t.c 和 t.java 等,它会感到困惑
This doesn't even require a Makefile in the directory, although it will get confused if you have a t.cpp and a t.c and a t.java, etc etc.
也是一个真正的 Makefile:
Also a real Makefile:
SOURCES := t.cpp
# Objs are all the sources, with .cpp replaced by .o
OBJS := $(SOURCES:.cpp=.o)
all: t
# Compile the binary 't' by calling the compiler with cflags, lflags, and any libs (if defined) and the list of objects.
t: $(OBJS)
$(CC) $(CFLAGS) -o t $(OBJS) $(LFLAGS) $(LIBS)
# Get a .o from a .cpp by calling compiler with cflags and includes (if defined)
.cpp.o:
$(CC) $(CFLAGS) $(INCLUDES) -c $<
