Py-Boost build on win10 with MSVC

0. Download

• Visual Studio 2022
• CMake
• Conda
• Boost 1.79

1. Installation

• 开发人员命令提示符

• build

  cd \path\to\boost_1_79_0
  call bootstrap.bat
  

  出现b2.exe, 接着安装

  rem Visual Studio 2012 -> set msvcver=msvc-11.0
  rem Visual Studio 2013 -> set msvcver=msvc-12.0
  rem Visual Studio 2015 -> set msvcver=msvc-14.0
  rem Visual Studio 2017 -> set msvcver=msvc-14.1
  set msvcver=msvc-14.1
  
  rem conda python=3.7 env
  conda create -n pyboost python=3.7
  conda activate pyboost
  
  b2 stage --stagedir=stage/x64 --with-python toolset=%msvcver% address-model=64 link=static threading=multi runtime-link=shared --build-type=complete -j8
  

  b2参数比较多，可参考boost b2/bjam 参数说明

  如果不报错，生成py-boost的静态库。如果想生成全部的Boost库，将--with-python去掉即可。

  

  [可选]把生成的lib拷贝到C:/local/

  set boost_dir=%cd%
  cd C:/
  mkdir local
  
  xcopy %boost_dir%\stage\x64\lib\*.lib .\local\lib /s /y /q
  xcopy %boost_dir%\stage\x64\lib\*.dll .\local\bin /s /y /q
  xcopy %boost_dir%\boost\* .\local\include\boost\ /s /y /q
  

2. Using PyBoost

2.1.a Visual Studio Setup

• include

  项目 -> 属性 -> VC++目录 -> 包含目录

  包含python以及刚编译成功的Python-Boostinclude目录

  

• lib

  项目 -> 属性 -> VC++目录 -> 库目录

  包含python以及刚编译成功的Python-Boostlib目录

  

• 输出设置

  项目 -> 属性 -> 常规 -> 配置类型 & 目标文件扩展名

  先设置配置类型为.dll，目标文件扩展名为.pyd

  

  Visual Studio Setup 可以参考Windows 安装 Boost Python 并使用 Visual Studio 2019 或 Clion 编译 (Python调用C++)

• build .pyd

  在Visual Studio中，Relase x64模式，生成 -> 生成解决方案。在\x64\Release\下获取PyBoostTest.pyd

2.1.a CMake Setup

除了使用Visual Studio外，也可以使用CMake工具帮助build

• CMakeLists.txt

  cmake_minimum_required(VERSION 3.21)
  project(PyBoostTest)
  
  # C++ 17
  set(CMAKE_CXX_STANDARD 17)
  
  # include
  set(INCLUDE_H ${PROJECT_SOURCE_DIR}/inc)
  set(INCLUDE_ADD "path\to\boost\include" 
                  "path\to\python\include")
  include_directories(${INCLUDE_H} ${INCLUDE_ADD})
  
  # lib
  set(LIB_PATH ${PROJECT_SOURCE_DIR}/lib)
  set(LIB_ADD "path\to\boost\libs" 
              "path\to\python\lib")
  file(GLOB_RECURSE LIB_FILES ${LIB_PATH}/*.lib ${LIB_add}/*.lib)
  link_directories(${LIB_PATH} ${LIB_ADD})
  
  message("*** LIB_PATH: ${LIB_PATH}")
  message("*** LIB_FILES: ${LIB_FILES}")
  
  # src
  aux_source_directory(${PROJECT_SOURCE_DIR}/src DIR_SRCS)
  
  # pyd
  add_library(PyBoostTest ${DIR_SRCS})
  target_link_libraries(PyBoostTest ${LIB_FILES})
  
  # suffix
  set (EXT ".so")
  if (WIN32)
      set (EXT ".pyd")
  endif()
  set_target_properties(PyBoostTest PROPERTIES PREFIX "" SUFFIX ${EXT})
  

• CMake --build

  mkdir build
  cd build
  cmake "Visual Studio 15 2022" -A x64 ..
  cmake --build . --config Release -- /maxcpucount:8
  

  一样获取PyBoostTest.pyd

2.2 Code

• 具体测试源码见PyBoostTest

• .pyd文件PyBoostTest.pyd

• Wrapper

  #define BOOST_PYTHON_STATIC_LIB
  #include <boost/python.hpp>
  #include <boost/python/module.hpp>
  #include <boost/python/def.hpp>
  
  #include <iostream>
  #include "Num.h"
  
  using namespace boost::python;
  using namespace std;
  
  char const* greet() 
  {
      return "hello, world";
  }
  
  int generateZero()
  {
      return 0;
  }
  
  void printNum(Num & num)
  {
      std::cout << num.get() << std::endl;
  }
  
  BOOST_PYTHON_MODULE(PyBoostTest)
  {
      // 普通 python 函数
      def("greet", greet);
      def("generateZero", &generateZero);
      def("printNum", &printNum);
  
      // 类
      class_<Num>("Num", init<>()) // init<>()默认构造
          .def(init<float>()) // 有参构造
          .def("get", &Num::get) // 成员函数
          .def("set", &Num::set)
          .def("clear", &Num::clear)
      ;
  }
  

  BOOST_PYTHON_MODULE(module_name)对外输出，其中module_name会与最终输出的.pyd名称对上，也即在python中，import module_name

  Boost.Python语法可以参考boost.python笔记。

2.3 Run

• in python test code PyBoostTest

  import PyBoostTest
  
  def test_pyBoost():
      print(PyBoostTest.greet()) # say hello world
      num_a = PyBoostTest.generateZero() # generate num 0 -> num_a
  
      num_A = PyBoostTest.Num(2.5) # Class Num() -> num_A object
      PyBoostTest.printNum(num_A) # print object num_A
  
      num_A.set(10.0) # set
      print(num_A.get()) # get
  
      num_A.clear() # clear data
      PyBoostTest.printNum(num_A)
  
  
  if __name__ == "__main__":
      test_pyBoost()
  

• result
