This project demonstrates how to create a Go (golang) package from a C++ class using SWIG.
This code was originally for a blog post here: http://zacg.github.io/blog/2013/06/06/calling-c-plus-plus-code-from-go-with-swig/, but the instructions refer to earlier versions of Go (before 1.5) and SWIG (before 3.0).
#####Getting Started
go get github.com/zacg/simplelib
cd $GOPATH/src/github.com/zacg/simplelib
go install
go test
#####Example Application Code
You an also look at the unit tests in simplelib_test.go.
package main
import (
"fmt"
"github.com/zacg/simplelib"
)
func main() {
simpleClass := simplelib.NewSimpleClass()
result := simpleClass.Hello()
fmt.Println(result)
strings := simplelib.NewStringVector()
simpleClass.HelloString(strings)
var i int64
for i = 0; i < strings.Size(); i++ {
fmt.Println(strings.Get(int(i)))
}
bytes := simplelib.NewByteVector()
simpleClass.HelloBytes(bytes)
for i = 0; i < bytes.Size(); i++ {
fmt.Printf("%c", bytes.Get(int(i)))
}
fmt.Println("")
}
