您好，我正在使用qml库来创建UI。我正在尝试学习如何从UI(qml)传递信息，然后“做某事”。如果QML只是一个UI，它就可以工作。当我这样做时，我可以运行得很好:funcmain(){iflen(os.Args)!=2{fmt.Fprintf(os.Stderr,"usage:%s\n",os.Args[0])os.Exit(1)}iferr:=qml.Run(run);err!=nil{fmt.Fprintf(os.Stderr,"error:%v\n",err)os.Exit(1)}}funcrun()error{engine:=qml.NewEngine()engine.On

我能否将*[]string从Go传递给C，然后append到字符串slice，或者它是否违反了pointerpassingspec？GocodemaypassaGopointertoC,providedtheGomemorytowhichitpointsdoesnotcontainanyGopointers.示例代码:packagemain/*externvoidgo_callback(void*,char*);staticinlinevoidcallback(void*stringSliceGoPointer){go_callback(stringSliceGoPointer,"fo

在编写利用网络的程序时，您会发现CGO_ENABLED=0的编译速度明显变慢。例如最简单的HTTP服务器:packagemainimport("flag""fmt""log""net/http")funchandler(whttp.ResponseWriter,r*http.Request){fmt.Fprintf(w,"Hi!gladyourequested%s.\n",r.URL.Path[1:])}funcmain(){port:=flag.Int("port",9000,"")flag.Parse()http.HandleFunc("/",handler)err:=http.L

看完StaticallycompiledGoprograms,always,evenwithcgo,usingmusl我正在尝试使用描述的方法静态链接LuaJIT.使用https://github.com/aarzilli/golua去绑定(bind)假设musl和golua已经安装我尝试构建的Go代码:packagemainimport"github.com/aarzilli/golua/lua"import"fmt"functest(L*lua.State)int{fmt.Println("helloworld!fromgo!")return0}functest2(L*lua.St
