编译时出现Boost.python链接错误

我正试图构建受启发的示例

我的初衷是能够从Python中调用C++代码。为了实现这个目标，我只是运行Boost文档中的示例。

这是我的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)/*

这导致以下错误

我做错了什么？
