从*.pyd库中的C++ Boost Python方法

早安,我对boost::python中的简单示例有一些问题-所有必须返回除char const*或create class以外的任何类型的方法都不会返回任何内容,所有我看到的都是它的RESTART: Shell。你知道吗

我正在使用:

  • CLion 2018.3.3,建造#CL-183.5153.40,建造于2019年1月10日
  • MinGW-w64\x86\u 64-8.1.0-posix-seh-rt\u v6-rev0
  • CMake 3.13.0-rc1-
  • Python 3.7(x86_64)
  • 升压1.68.0

它是用下一个参数构建的:

bootstrap gcc 
b2 -j12 toolset=gcc runtime-link=shared architecture=x86 address-model=64 --with-python cxxflags="-D__int64=\"long long int\" -DBOOST_REGEX_MATCH_EXTRA -D__NO_INLINE__ -D_hypot=hypot"  --build-type=complete --layout=tagged stage

你知道吗CMakeList.txt文件包含:

cmake_minimum_required(VERSION 3.13)
project(pylibtest)

set(CMAKE_CXX_STANDARD 17)

set(GCC_COVERAGE_COMPILE_FLAGS "-march=native  -m64 -D_hypot=hypot -static -static-libstdc++ -static-libgcc -Wall")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${GCC_COVERAGE_COMPILE_FLAGS}" )

message(STATUS "start running cmake...")

set(Boost_DEBUG                 OFF)
#set(Boost_USE_STATIC_LIBS       ON)
set(Boost_USE_MULTITHREADED     ON)
#set(Boost_USE_STATIC_RUNTIME    ON)

find_package(Boost 1.68.0 COMPONENTS python37 REQUIRED)
if(NOT Boost_FOUND)
    set(Boost_LIBRARY_DIR "${Boost_Path}/stage/lib")
    message(STATUS "Boost_LIBRARIES: ${Boost_LIBRARY_DIR}")
    message(STATUS "Boost_VERSION: ${Boost_VERSION}")
    include_directories(${Boost_INCLUDE_DIRS})
    link_directories(${Boost_LIBRARIES})
endif()

find_package(PythonInterp 3.7 REQUIRED)
find_package(PythonLibs 3.7 REQUIRED)
if(PYTHONLIBS_FOUND)
    message(STATUS "PYTHON_LIBRARIES = ${PYTHON_LIBRARIES}")
    message(STATUS "PYTHON_EXECUTABLE = ${PYTHON_EXECUTABLE}")
    message(STATUS "PYTHON_INCLUDE_DIRS = ${PYTHON_INCLUDE_DIRS}")
    include_directories(${PYTHON_INCLUDE_DIRS})
    link_directories(${PYTHON_LIBRARIES})
endif()

if(Boost_FOUND AND PYTHONLIBS_FOUND)
    add_library(pylibtest SHARED library.cpp library.h wrap.cpp Some.cpp Some.h)
    target_include_directories(pylibtest SYSTEM PRIVATE  ${Boost_INCLUDE_DIRS} ${PYTHON_INCLUDE_DIRS})
    target_link_libraries(pylibtest ${Boost_LIBRARIES} ${PYTHON_LIBRARIES})
endif()

你知道吗包装.cpp包含python模块中的所有方法及其定义:

#include <boost/python.hpp>
//#include "Some.h"

using namespace boost::python;

char const* SayHello()
{
    return "Hello, from c++ dll!";
}

int GetMeNumber(){
    int temp = 255;
    return temp;
}

BOOST_PYTHON_MODULE( example )
{
    def("SayHello", SayHello);
    def("GetMeNumber", GetMeNumber);
}

IDLE 3.7(64位)中的Python脚本:

print("Procedure started:")
import example
print(example.SayHello())
print("Procudure ended")
print("-=-=-=-=-=-=-=-=-=-=-=-")
print("New procedure started")
count = example.GetMeNumber();
print(count)
print("New procudure ended")

在Python 3.7.0 Shell中:

Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> 
===== RESTART: C:\..\pi.py =====
Procedure started:
Hello, from c++ dll!
Procudure ended
-=-=-=-=-=-=-=-=-=-=-=-
New procedure started

=============================== RESTART: Shell ===============================
>>> 

当我尝试在PyCharm中使用相同的脚本时,我得到了一条错误代码消息:

Procedure started:
Hello, from c++ dll!
Procudure ended
-=-=-=-=-=-=-=-=-=-=-=-
New procedure started

Process finished with exit code -1073741819 (0xC0000005)

有人知道我的out lib有什么问题吗?还有什么更好的方法可以让它发挥作用?你知道吗
