Hi all,
I am having trouble with a really simple example, and I am hoping someone on
this list can help me.
I have created a github repo for code in question:
git clone g...@github.com:brianbruggeman/boost_python_hello_world.git
I have also created a stack overflow question:
http://stackoverflow.com/q/25533329/631199
The basic problem is as follows:
Currently, I am able to compile cleanly, but when executing the code, I
receive a segmentation fault. I've narrowed the seg-fault down to the line
which actually uses boost::python::extract.
Code:
#include <boost/python.hpp>
#include <iostream>
namespace bp = boost::python;
// Embedding python
int main(int argc, char** argv) {
int data = 0;
Py_Initialize();
PyRun_SimpleString("data = 1");
bp::object
module(bp::handle<>(bp::borrowed(PyImport_AddModule("__main__"))));
bp::object dictionary = module.attr("__dict__");
bp::object data_obj = dictionary["data"];
// Error: The following line has the segmentation fault...
data = bp::extract<int>(data_obj);
std::cout << "data = " << data << std::endl;
Py_Finalize();
return 0;
}
CMakeLists.txt:
project(hello)
cmake_minimum_required(VERSION 2.8)
FIND_PACKAGE(PythonInterp)
FIND_PACKAGE(PythonLibs)
FIND_PACKAGE(Boost COMPONENTS python)
include_directories(${PYTHON_INCLUDE_DIRS} ${Boost_INCLUD_DIRS})
link_directories(${PYTHON_LIBRARY_DIRS} ${Boost_LIBRARY_DIRS})
add_executable(hello say_hello.cpp)
target_link_libraries(hello
${Boost_LIBRARIES}
${PYTHON_LIBRARIES})
Also for completeness…
I installed Python and Boost::Python using the following…
brew install python
brew install boost —with-python
Thanks so much in advance!
