build problem

[DuyHuynhLe]

Hello, I'm trying to build the project and these errors appear. Could you help me find a resolve this problem? My system is Debian Jessie with OpenCV 2.4.9,

Hello, what compiler are you using? (g++ which version? )

[DuyHuynhLe]

I'm using gcc version 4.9.2 (Debian 4.9.2-10)

sorry, can not reproduce the error.,

what you can do: run make VERBOSE=1 (this will print full g++ command with parameters) and observe, if all include directories are correct.

if yes, check if the required function PyInt_FromLong is visible. the PyAPI_FUNC(PyObject *) PyInt_FromLong(long) shoud be declared in file intobject.h which shoud be included from Python.h
