A detailed explanation of the dynamic Link Library of the method of python calling Candlestick + in ubuntu
Install boost
There are many ways for python to call CramCure +, and boost.python is used in this article. Considering that there are a lot of development work on boost in the later stage, boost is installed together, and the Boost library is divided into two parts to use, one is to use the corresponding header file directly, and the other is to compile and install the corresponding library before you can use it.
For specific installation methods, please refer to: https://www.jb51.net/article/150380.htm
The use here is:
Sudo apt-get install libboost-all-dev
Server side
Send after serialization
Main.cpp:
# include # include "libUO.h" int main () {UO_C_Socket t UO_C_Socket::StartSocketServer,&t / t.StartSocketServer (", 4121); boost::thread T1 (boost::bind (& UO_C_Socket::StartSocketServer,&t,", 4121)); sleep (2); / / boost::thread T2 (boost::bind (& UO_C_Socket::StartSocketClient,&t, "127.0.0.1", 4121)); / / t2.join (); t1.join (); return 0;}
Client
The client implements basic functions in UO_BaseFun.h, encapsulates it and exports it through boost_python. Pay special attention to the name in BOOST_PYTHON_MODULE and the so file from the last make.
The same name, otherwise there will be an error, the wrong name has been forgotten
UO_libdll_py_wrap.cpp:
# include # include "UO_BaseFun.h" BOOST_PYTHON_MODULE (UO_BaseFun) / / python module {/ / boost::python::class_ ("UO_C_Socket") boost::python::class_ ("UO_C_Socket") .def ("StartSocketClient", & UO_C_Socket::StartSocketClient) / / .def ("getname", & student::getname) / / .def ("setage") & student::setage) / / .def ("getage", & student::getage) / / .add _ property ("name", & student::getname,&student::setname) / / .add _ property ("age", & student::getage,&student::setage) }
Special attention is paid to the difference between compilation and linking in makefile, in which undefined symbol errors need to be added to the dynamic link library-lboost_filesystem and so on. An error that cannot find pyconfig.h should be included
-I/usr/include/python2.7. Generate a UO_BaseFun.so file after make is finished
Makefile:
UO_BaseFun.so:UO_libdll_py_wrap.o L/usr/lib/x86_64-linux-gnu + UO_libdll_py_wrap.o-o UO_BaseFun.so-shared-fPIC-L/usr/lib/x86_64-linux-gnu\-lboost_filesystem-lboost_thread-lboost_serialization-lboost_python-lboost_system UO_STR.o: Gmail +-c UO_STR.h-o UO_STR.o-I/usr/include/boost\ #-lboost_serialization UO_BaseFun.o:UO_STR.o Gmail +-c UO_BaseFun.h-o UO_BaseFun.o-I/usr/include/boost\ #-lboost_system-lboost_filesystem-lboost_thread-lboost_serialization UO_libdll_py_wrap.o:UO_BaseFun.o Gmail +-c UO_libdll_py_wrap.cpp-o UO_libdll_py_wrap.o-fPIC-I/usr/include/python2.7 #-lboost_serialization clean: rm-rf UO_STR.o O_libdll_py_wrap.o UO_BaseFun.o rm-rf UO_BaseFun.so
Verification
UO_StoreSystem_py.py:
Import UO_BaseFuntest = UO_BaseFun.UO_C_Socket () test.StartSocketClient ("127.0.0.1", 4121)
