问题 I am writing an application which must spawn and detach a new process which has a separate console window which can be used for user input and output. Ideally the solution should be cross platform and a solution which uses Boost is even better (since Boost is already used extensively within this project). I have already tried boost::process::spawn but that only launches the new process in the same console window as the the main process. CreateProcess (in the Win-API) with the CREATE_NEW

问题 I would like to know if Boost Ptree allows parsing .xml files without having the attribute tags known. I have an XML file that will regularly be updated with new tags, new data, and even remove certain tags. These regular changes prompted me to look into parsing the file without hardcoding the attribute name. Is there any way I can read all the data in the XML file without stating the tag name? Any help is appreciated! 回答1: Ptrees aren't ideal for parsing XML but Boost is so integrated into

问题 I am trying to setup and compile the Hello World example for Boost.Python: http://www.boost.org/doc/libs/1_57_0/libs/python/doc/tutorial/doc/html/python/hello.html I installed bjam, boost, boost-build, and boost-python from Homebrew: brew install bjam brew install boost brew install boost-build brew install boost-python My python install is also via Homebrew. I am not sure how to properly modify the example Jamroot file so that it is compatible with my system setup. I changed the boost path

问题 I am using the boost::python library in this tiny mwe. #include <deque> #include <boost/python.hpp> typedef std::deque<long unsigned int> DequeUInt64; BOOST_PYTHON_MODULE_INIT(tmp) { boost::python::class_<DequeUInt64>("DequeUInt64") .def("push_back" ,&DequeUInt64::push_back) .def("push_front" ,&DequeUInt64::push_front); } I observed that the code above compiles with std=c++03 and gnu++03 but not with c++11 or c++0x . The error is: tmp.cpp: In function 'void init_module_tmp()': tmp.cpp:8:47:
