How to use python "include" and "libs" path in a windows makefile to compile all python embedded C++ program in a folder?

Question

Makefile specified in this question, compiling all the cpp programs in a folder but not with python embedded cpp programs.

all: myUB

sourcesC := $(wildcard ../src/*.cpp)

objectsC := $(patsubst %.cpp,%.o,$(sourcesC))

INPATH=-I"C:/Python27/include"

LIBPATH=-L"C:/Python27/libs"-lpython27

myUB:

    @echo 'Building target $@'

    g++ -O0 -Wall -c -g3 -fmessage-length=0 \
        $(sourcesC)

    del *.o

clean:

Answer 1

Your final makefile could look somthing like:

all: myUB

sourcesC := $(wildcard ../src/*.cpp)

# Not used
#objectsC := $(patsubst %.cpp,%.o,$(sourcesC))

INC = -IC:\Python27\include

LIBS = -LC:\Python27\libs -lpython27

myUB:
    @echo 'Building target $@'
    g++ -O0 -Wall -g3 -fmessage-length=0 -o myprog.out $(sourcesC) $(INC) $(LIBS)

clean:
    rm myprog.out

update

For the undefined ref to WinMain(), it means the linker can't find this function in your code. Either you need to include a library/object that contains it or you can define it yourself in a cpp file like:

#include <windows.h>

int WINAPI (*MyDummyReferenceToWinMain)(HINSTANCE hInstance, ..., int
nShowCmd ) = &WinMain;

I got the function template from here.

But this seems to mean that you are creating a windows application instead of a console app which uses int main(...) entry point.

Update2

I have made a new makefile to do what you have asked for in your latest comment which seems to be to create one executable per source file - I am assuming each source file has its own main.

# Build vars
CXX = g++
CXX_FLAGS = -O0 -Wall -g3
INC = -IC:\Python27\includ
LIBS = -LC:\Python27\libs -lpython27

# Sources
SRC_DIR=src
SOURCES = $(wildcard $(SRC_DIR)/*.cpp)
$(info SOURCES: $(SOURCES))

# Executables
EXE_DIR=bin
EXECUTABLES = $(subst $(SRC_DIR)/,$(EXE_DIR)/,$(subst cpp,out,$(SOURCES)))
$(info EXECUTABLES: $(EXECUTABLES))

$(info ----)

# Directories
DIRS = $(EXE_DIR)

# Rule to create folders and compile executables
all: $(DIRS) $(EXECUTABLES)

# Pattern rule to build each executable
$(EXE_DIR)/%.out : $(SRC_DIR)/%.cpp
    @echo "compiling $< --> $@"
    @$(CXX) $(CXX_FLAGS) -o $@ $< $(INC) $(LIBS)

# Rule to create output dirs
$(DIRS):
    @echo "Creating output folders"
    @mkdir -p $(EXE_DIR)

# Rule to clean up
clean:
    @echo "Cleaning"
    @rm -rf $(EXE_DIR)

This should create one executable in the folder bin/ for each source file (.cpp) in folder src/.
