swig

I cannot reproduce the basic SWIG example on windows. My error is stated in the SWIG docs and I am sure that I do the 2 fixes they mention. For this error: >>> import example Traceback (most recent call last): File "<stdin>", line 1, in ? File "example.py", line 2, in ? import _example ImportError: No module named _example the SWIG documentation clearly states: forget the leading underscore (_). forget the leading underscore (_).> If you get this message, it means that you either forgot to compile the wrapper code into an extension module or you didn't give the extension module the right name.

I am trying to get Python running with swig to do C/C++. I am running the tutorial here , 'building a python module'. When I do the call gcc -c example.c example_wrap.c -I /my_correct_path/python2.5 I get an error: my_correct_path/python2.5/pyport.h:761:2: error: #error "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)." example_wrap.c: In function 'SWIG_Python_ConvertFunctionPtr': example_wrap.c:2034: warning: initialization discards qualifiers from pointer target type example_wrap.c: In function 'SWIG_Python_FixMethods': example_wrap.c:3232: warning: initialization

I'm working on TensorFlow and I want to know the relationship between each Python function and the correspondent C++ functions behind the SWIG interface. In other words, I want to be able to know exactly which C++ functions are invoked for every line of Python code of my TensorFlow application. I already saw how to debug the Python code here and how to display at which line of code a segmentation fault happens here , but in these ways I'm able to see only where an error is, while instead I want to be able to know every C++ function invocation, even when there are no bugs in the code (At the

I've got a library that takes in a very simple C image structure: // Represents a one-channel 8-bit image typedef struct simple_image_t { uint32 rows; uint32 cols; uint8 *imgdata; } simple_image; I didn't create this library, nor this structure, so I can't change it. I'm responsible for wrapping this library for python using SWIG. The Python wrapper needs to be able to take in a PIL Image and convert it into this structure. Here's how I'm doing it right now (using a SWIG %inline% ): // Allows python to easily create and initialize this structure simple_image* py_make_simple_image(uint32 width,

My goal is to use the C libraries to form web apps. I have choosen the way to do that via using "SWIG" tool. The Swig tool requires three things 1) .c file which defines all the functions. 2) .i file also called interface file which is creating the interface to load the APIs wherin I used the extern keyword. 3) APP written in javascript extension (.js file). I used SWIG tool to compile and run this app to verify the .js file has made correctly. The application is running fine on XMING X11 window. On compilation it creates _wrap.o, .o file and libFILENAME.so Now I want to run this app on

example.h : #ifndef EXAMPLE_H #define EXAMPLE_H class Math { public: int pi() const; void pi(int pi); private: int _pi; }; #endif example.cpp : #include "example.h" int Math::pi() const { return this->_pi; } void Math::pi(int pi) { this->_pi = pi; } example.swig : %module example %{ #define SWIG_FILE_WITH_INIT #include "example.h" %} %include "example.h" I then generate the wrappers, "example.py" and "example_wrap.c" using: swig -python example.swig When I try to compile the wrapper class using: g++ -fPIC -c example.cpp example_wrap.c -I/usr/local/include/python2.6/ I get the following error:

I used SWIG to wrap my c++ class. Some methods have a const std::string& as a parameter. SWIG creates a type called SWIGTYPE_p_std__string however you cannot just pass a normal string for this when invoking the method in c#. The below example is just a modified example that comes with the SWIG package.: public void setName(SWIGTYPE_p_std__string name) { examplePINVOKE.Shape_setName(swigCPtr, SWIGTYPE_p_std__string.getCPtr(name)); if (examplePINVOKE.SWIGPendingException.Pending) throw examplePINVOKE.SWIGPendingException.Retrieve(); } In my interface file I just have: /* File : example.i */
