I want to use golang call c++ dll with swig on windows. (gc compiler, on Linux was successful.) But there have some problems. Here is the sample.
//sampel.h
int compute(int a, int b);
//sample.cpp
#include <iostream>
#include "sample.h"
int compute(int a, int b){
int temp = (a+b)*(a-b);
return temp;
}
//sample.i
%module sample
%inline %{
#include "sample.h"
%}
int compute(int a,int b);
Now, I use this cmd to generate the wrap files:
swig -c++ -go -soname sample.dll -intgosize 64 sample.i
Then create an empty dll project in VS, add sample.h too Header Files, add sample.cpp and sample_wrap.cxx to Source Files, add sample.i to the project.
Build Solution, generates sample.dll
Use cmd as below to generate sample.a:
go tool 6g sample.go
go tool 6c -I C:\Go\pkg\windows_amd64 sample_gc.c
go tool pack grc sample.a sample.6 sample_gc.6
Next, install sample.a(to avoid some issue), then run the test.go:
package main
import (
"fmt"
"sample"
)
func main() {
fmt.Println(sample.Compute(3, 4))
}
The problem is here, when I run test.go, got the error:
adddynlib: unsupported binary format
How do I fix the problem(dll and test.go is in the same directory)? Thanks! If you need extra information that I missed, just ask.
