Good day, I have a few problems with simple examples from boost::python - All methods that must return any types except char const* or create Classes doesn't return anything and all what do I see its RESTART: Shell.
I'm using:
- CLion 2018.3.3, Build #CL-183.5153.40, built on January 10, 2019;
- MinGW-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0;
- CMake 3.13.0-rc1-;
- Python 3.7 (x86_64);
- boost 1.68.0,
which was built with the next arguments:
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
CMakeList.txt contains:
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_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}")

endif()
find_package(PythonInterp 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()
wrap.cpp which are contains all methods and they definitions in python module:
#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);
}
The Python script in IDLE 3.7 (64 bit):
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")
And the out in Python 3.7.0 Shell:
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 ===============================
>>>
When I tried to use same script in PyCharm I've got the out with error code message:
Procedure started:
Hello, from c++ dll!
Procudure ended
-=-=-=-=-=-=-=-=-=-=-=-
New procedure started
Process finished with exit code -1073741819 (0xC0000005)
Does any one know what's wrong with my out lib and what is the better way to make its work?
