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

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/.
