使用 python 编译/链接 C++ 项目

Question

So i have a somewhat large C++ project that I want to compile.Previously I used Code::Blocks, but now I want more control about what's happening behind the scenes. However making makefiles was just too complex for me!!

What I want is this: Can i create a python script that acts as a makefile, if so how?!

In the makefile I want to search for all *.cpp files on certain directories and then invoke g++ to compile/link them.

EDIT: sorry i forgot to mention i also have headers and want custom g++ parameters

Answer 1

Try scons

It looks like what you need

Answer 2

Try that:

#default target
all: prog

#auto dependency

include $(OBJ_FILES:.o=.d)

%.o: %.cpp
    $(CXX) -c $(CXXFLAGS) $*.cpp -o $*.o
    $(CXX) -MM $(CXXFLAGS) $*.cpp > $*.d
    @mv -f $*.d $*.d.tmp
    @sed -e 's|.*:|$*.o:|' < $*.d.tmp > $*.d
    @sed -e 's/.*://' -e 's/\\$$//' < $*.d.tmp | fmt -1 | \
    sed -e 's/^ *//' -e 's/$$/:/' >> $*.d
    @rm -f $*.d.

#set ld flags eg for libs
LDFLAGS = -lsdl2 -lglew -lgl

#set cxxflags for all debug options and others
CXXFLAGS= -g -Wall

#collect all cpp files:
CPP_FILES := $(shell find . -type f -name '*.cpp')

#get the object file names for them
OBJ_FILES := $(CPP_FILES:.cpp=.o)

#and link all togeter
prog: $(OBJ_FILES)
    g++ $(CXXFLAGS) $(LDFLAGS)  -o $@ $^
