Using C++ classes from Go using Swig

Question

I want to use C++ class from Go using swig in Windows7

When I build the project "go build main.go" I am getting following error:

c:\\..\\Temp\\go-build591352403/swtest.a(swtest_wrap.o): malformed pe file: __cgo_topofstack: invalid symbol binding 105

I am using go 1.3 32bit, gcc 4.8.1 32bit and swig 3.0 in Windows7. I see same error when I use 64bit Go and GCC in Windows7.

I am able build and run successfully on Ubuntu with 64-bit go and gcc.

Am I missing something in windows?

Here is the file structure and content.

main (folder)

• main.go

   package main import ( "swtest" ) func main() { swtest.NewSwt().Print("Swig test!") } 

swtest (folder)

• swtest.cpp

   #include "swtest.h" void Swt::Print(const std::string& s) { std::cout << s; std::cout << std::endl; } 

• swtest.h

    #ifndef SWTEST_H #define SWTEST_H #include <string> #include <iostream> class Swt { public: void Print(const std::string& s); }; #endif 

• swtest.go

    package swtest 

• swtest.swigcxx

   %module swtest %include "std_string.i" %{ #include "swtest.h" %} %include "swtest.h"
