swig

I am trying to create Java implementation for passing byte [] to C using Swig. Swig: %include "typemaps.i" %apply(char *STRING, int LENGTH) { (char *buff, int len) }; %inline { typedef struct { char* buff; int len; } workit_t; } In my generated java class (workit_t.java), the parameter buff is a String, instead of a byte []. Java: public void setBuff(String value){ ... } What am I doing wrong in my swig definition? When I write a simple swig definition with no struct, I get the desired type of parameter. Swig: %include "typemaps.i" %apply(char *STRING, int LENGTH) { (char *buff1, int *len1) };

I'm developing a module for using c inline in Python code based on swig . For that I would like to make numpy arrays accessible in C . Until now I used C types like unsigned short but I would like to use types like uint16_t from stdint.h to be save whatever compiler my module encounters. Unfortunately the c++ -functions do not get wrapped correctly when using stdint.h types. The Error given is: _setc() takes exactly 2 arguments (1 given) . That means, the function is not wrapped to accept numpy arrays. The error does not occur, when I use e.g. unsigned short . Do you have any ideas, how I can

I'm trying to print C++ classes that I wrapped for Python using SWIG. I have followed the documentation and this question: How to stringfy a swig matrix object in python The extended __str__ function is there, but it isn't called when I print the object from Python. Let me give a minimal example: TestClass.h #include <iostream> class TestClass{ private: int my_int; public: TestClass(): my_int(0) {} friend std::ostream& operator<< (std::ostream& o, TestClass const& t){ o<< "TestClass: " << t.my_int; return o; } }; TestClass.cpp #include "TestClass.h" int main(){ using namespace std; TestClass t

I'm trying to convert a member of structure of type signed char * to byte array in Java. I've the following structure: typedef struct { signed char * content; int contentLength; } Foo; I've tried this: %typemap(jni) signed char *content [ANY] "jbyteArray" %typemap(jtype) signed char *content [ANY] "byte[]" %typemap(jstype) signed char *content [ANY] "byte[]" %typemap(javaout) signed char *content [ANY] { return $jnicall; } %typemap(memberin) int contentLength [ANY] { int length=0; $1 = &length; } %typemap(out) signed char * content [ANY] { $result = JCALL1(NewByteArray, jenv, length); JCALL4

Currently I have a set of SWIG wrappers for my classes and it all builds. I can create a lua virtual machine and load my wrappers, but at that point I'm flummoxed. Googling tells me how to shove put c++ in lua in swig, but not how to put lua in c++. Really all I want to do is manage to instantiate a lua object and pass it my main game engine object pointer, from there I can manage Take a look at the Programming in Lua book, it has a section on the Lua C API . For calling Lua functions use lua_pcall , which is equivalent to lua_call (that has a short example) except it will catch Lua runtime

I'm trying to create a *.so file for further use in Python using SWIG, but something isn't working. I have two files: DataGatherer.h #include <iostream> #include <stdlib.h> #include <time.h> #include "gnublin.h" #include <pthread.h> class dataGatherer { private: int threshold; int timeThreshold; int data[4096]; bool running; gnublin_spi* spiDevice; pthread_t spiThread; void *params; public: dataGatherer(void); dataGatherer(int, int); void initData(); int getThreshold(void); int* getData(void); int getPeak(void); void initSPI(void); void gatherData(); void * run(void * arg); void stop(void); //
