Golang use C library

• cgo can compile C code
• cgo can not compile C++ code (see Swig for that)
• cgo supports both dynamic and static linking of compiled C code
• by default, cgo will dynamically link (more on this later)
• cgo does not support relative lookups of C files
• #cgo pkg-config

Example :

$ vi test.go

package main

import "fmt"

// #cgo CFLAGS: -I.
// #cgo LDFLAGS: -L. -lgb 
// #include 
import "C"

func main() {
    fmt.Printf("Invoking c library...\n")
    fmt.Println("Done ", C.x(10) )
}

$ go build test.go
