编译时将错误与Boost.python链接 [英] Linking error with Boost.python while compiling
问题描述
正在尝试构建受这里
我的初衷是能够从Python内部调用C ++代码.我只是运行Boost文档中的示例以实现此目标.
My original intention is to be able to call C++ code from within Python. I'm just running the examples from the Boost documentation in order to achieve this goal.
这是我的makefile文件
Here's my makefile
CXX := g++
CXX_FLAGS := -Wall -Wextra -std=c++17 -ggdb
BIN := bin
SRC := src
INCLUDE := inc
LIB := lib
BOOST_ROOT := /home/eicossa/repo/boost_install
BOOST_INCL := ${BOOST_ROOT}/include/
BOOST_LIBS := ${BOOST_ROOT}/libs/
PYTHON_INCL := /usr/include/python3.7m/
PYTHON_LIBS := /usr/lib/python3.7/
LIBFLAGS := -lboost_system
EXECUTABLE := greet
all: $(BIN)/$(EXECUTABLE)
run: clean all
clear
./$(BIN)/$(EXECUTABLE)
$(BIN)/$(EXECUTABLE): $(SRC)/*.cpp
$(CXX) $(CXX_FLAGS) -I$(PYTHON_INCL) -I$(INCLUDE) -I$(BOOST_INCL) -L$(BOOST_LIBS) -L$(PYTHON_LIBS) -L$(LIB$
clean:
-rm $(BIN)/*
这会导致以下错误

我在做什么错了?
