英文:
use swig -go on windows with Visual Studio
问题
我想在Windows上使用golang调用带有swig的C++ dll。（在Linux上使用gc编译器是成功的。）但是遇到了一些问题。这里是示例代码。
//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);
现在，我使用以下命令生成包装文件：
swig -c++ -go -soname sample.dll -intgosize 64 sample.i
然后在VS中创建一个空的dll项目，将sample.h添加到Header Files，将sample.cpp和sample_wrap.cxx添加到Source Files，将sample.i添加到项目中。
构建解决方案，生成sample.dll
使用以下命令生成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
接下来，安装sample.a（以避免某些问题），然后运行test.go：
package main
import (
"fmt"
"sample"
)
func main() {
fmt.Println(sample.Compute(3, 4))
}
问题出在这里，当我运行test.go时，出现了错误：
adddynlib: unsupported binary format
如何解决这个问题（dll和test.go在同一个目录中）？谢谢！如果你需要我遗漏的额外信息，请随时提问。

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.

根据SWIG教程和SWIG兼容性，它只适用于32位版本的Windows：
SWIG在所有已知的32位Windows版本中都能完美运行，包括95/98/NT/2000/XP。
英文:
According to SWIG Tutorial and SWIG Comparability, it works just with 32 bit versions of Windows:
SWIG also works perfectly well under all known 32 bit versions of Windows including 95/98/NT/2000/XP.
