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:
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
代码0xC0000005是
Access Violation
错误。你可以试着重复行政帐户下的所有内容。你知道吗相关问题 更多 >
